The sunshine in Omsi may be very complicated and in depth. There are a number of
kinds of mild that may be set individually. Solely an
interaction of all variants leads to a harmonious total lighting.
This tutorial explains the person variants and potentialities, the
functions and implementation.


Fundamental details about mild

Mild is a really complicated and
elaborate topic in Omsi. Whereas in actuality a light-weight supply (level of
mild) causes a light-weight shine and thus illuminates or brightens up
objects and the identical objects additionally forged shadows, in Omsi these
connections should be created individually and adjusted precisely.
Which means that you can’t merely set a light-weight supply, however you need to
set the sunshine, shadows and the sunshine sources and shades belonging to
the article individually. Furthermore, there may be additionally the chance to
create mild textures. Each single variant has its benefits however
additionally its disadvantages.

The large benefit, with the sunshine in
Omsi, is the top quality of the lighting, which may be achieved in
Omsi. The drawback, nonetheless, is the appreciable effort. The
increased the standard you wish to obtain, the extra effort you need to
make investments. Solely the correct interplay of the person potentialities
leads to the correct and virtually actual lighting ambiance in and on
the automobile. A 100% implementation continues to be not doable. One can
solely attempt to modify the sunshine as actual as doable.

On this
tutorial, it needs to be primarily concerning the lighting potentialities in
automobiles. For the article lighting, there are once more completely different types.
Solely the fundamentals are the identical. A sure foundation for the scripts are
sadly indispensable for this tutorial. Additionally, the creation of
3D objects can’t be mentioned right here. Due to this fact, the dealing with of a 3D
program is assumed to be given. Due to this fact, this text is proscribed to
the sunshine sorts and the settings, in addition to the implementation of
the sunshine.

There are a number of potentialities to convey mild
in or on a automobile. All collectively lead to a comparatively authentic
mild habits. The entries for the sunshine may be discovered within the
respective mannequin.cfg of a automobile. The sunshine management, i.e. when a
mild ought to go on or off, may be discovered within the scripts. There it’s
outlined when a light-weight variable has the state zero (mild off) or the
state one (mild on). Moreover, you can even equip a light-weight sort
with a dimmer. For an adjustment of the sunshine, the usage of a 3D
program shouldn’t be necessary. Nevertheless, relying on the article
building, it could be crucial to alter the 3D objects if the
mild habits is to be tailored or modified.


Thedifferent kinds of mild

For the automobiles in Omsi there
are 5 other ways to implement mild. Intimately these are:

Mild textures – these are placed on or modified,

factors – these are the sunshine sources that don’t produce any shine
however are seen,

Mild shine – the sunshine generated
independently of sunshine factors and solely brings the sunshine shine, i.e.
solely the sunshine impact,

Highlight – This mild belongs to the
automobile, solely produces the sunshine beam, however can solely illuminate
overseas objects that don’t belong to the automobile (map objects, AI
automobiles, passers-by).

Object Illumination – That is used to
illuminate objects with their daytime textures whatever the
precise brightness of the sport setting, after which create the
look of being illuminated.

Each single variant is
applied individually and independently from others. Collectively,
they kind the entire automobile lighting. The trouble for one of many
potentialities continues to be manageable. The complexity will increase, nonetheless,
if the person lighting choices are to be tailored to one another.


Fundamentals ofthe particular person lighting variants

The person lighting
variants may be applied fairly simply. Nevertheless, there are limits
in Omsi, which imply that one mild variant alone can be utilized, however
solely an interaction of a number of variants can produce a passable
outcome. The straightforward implementation of the person variants, however does
not make the composition in a automobile simple. In actuality, there’s a
mild supply that emits a light-weight beam, straight and straight from the
mild supply. Nevertheless, these mild rays can’t penetrate objects if
they don’t seem to be clear or the sunshine rays can’t penetrate the
density of the objects correctly. Thus, objects create shadows.
Moreover, mild rays mirror from objects. The brighter the
floor of an object, the extra mild rays mirror from the objects
and illuminate different objects not directly. In Omsi all objects are
penetrated. Due to this fact, no actual shadows are created in Omsi and no
mild rays are mirrored. These shadows and lightweight reflections should
be applied by textures. Due to this fact an interplay of all
potentialities is important for the standard, which sadly additionally
makes the hassle appreciable. Since a number of mild sources from
completely different instructions additionally affect the shadows of the objects, there
are limits in Omsi that affect the shading. Additional disadvantages
are the allowed variety of assignments of sunshine sources to an object
or the distinctive spot mild.



Mild textures can
be present in and across the bus in lots of locations. On the bus, for
instance, they function indicator lights, or for mild sources akin to
inside lights or lights on the bus, akin to headlights or
taillights. Mild textures are often present in locations which are
meant to light up one or a small group of sunshine factors or
illuminated objects.

Right here, an object is
mapped with so-called day textures, which the article exhibits when it’s
switched off. By altering the related variable, an evening texture is
both utilized or changed. The conversion is similar for each, solely
the corresponding command modifications. The change of the command causes
an object to behave as if it will be illuminated straight or
not directly. Through the day all objects are illuminated by the
Omsi-Solar. At evening these objects are now not illuminated. With the
assist of the feel change, one other texture is positioned or exchanged on
an object. This texture shall be displayed so brightly that this
texture seems as shining. The brighter the evening texture is, the
brighter the article shines. A darkish mild texture gives the look
of oblique lighting.


Advantagesand disadvantages of sunshine textures

Mild textures are
the simplest to implement of all different lighting variants. As a result of
brightness of the altering texture, the brightness may be managed
very simply through the feel. As well as, the brightness will also be
made dimmable by script. This implementation is a little more troublesome,
however nonetheless possible. As well as, mild textures may be set in coloration
by the textures. And in addition textures may be displayed brightly.

The three largest
disadvantages of sunshine textures are on the one hand that mild
textures cannot be switched on and off slowly (afterglow of the sunshine
our bodies). There’s solely the state on or off. Moreover, mild
textures haven’t any mild impact, so they can not illuminate different
objects within the bus. The final drawback is the purpose of
overluminescence. Not at all times the luminous fields are shielded in such
a means that the sunshine beneath doesn’t mild up neighbouring mild
fields a bit. This isn’t doable with mild textures.

Additionally the
implementation of sunshine textures shouldn’t be very simple, as a result of mild and
shades can or ought to seem collectively. Right here, a clear work with an
acceptable picture processing program is vital. One should not
neglect that many of the illuminated objects, like management lamps, are
managed by a light-weight bulb or a diode. So there’s a vibrant middle
level that loses some brightness to the surface.



Simple to implement

no sluggish switching on or off doable

Texture brightness determines the luminosity

Mild textures don’t produce any mild

Evening textures are utilized in another way

No transmission to adjoining objects

Objects may be made dimmable

Battery dependent brightness can solely be managed through scripts
(few ranges)

High quality determines look

no blasting doable

A number of the
disadvantages may be diminished by combining the opposite kinds of mild.
For instance, you should use the colors to simulate the distinction
between an incandescent lamp or an LED. The design of sunshine our bodies
additionally permits variations between easy incandescent lamps, halogen
lamps, LEDs or fluorescent tubes. The most important drawback is the
gradation of brightness. So you’ll be able to’t make mild textures dependent
on the capability of the battery. The much less battery capability there may be,
the darker the sunshine turns into. The utmost brightness is barely reached
when the engine and thus additionally the alternator is working and a most
on-board voltage of 26 volts (charging voltage) is utilized. With out
the engine working, the battery has solely a theoretical worth of
most 24 volts. In actual values the cost voltage is 26.8 volts and
the utmost battery voltage is 21.6 volts. This distinction can’t be
realized with mild textures in Omsi alone. The distinction between
working and stopped motor may be adjusted with the scripts. Right here,
too, the quantity of labor is decisive for the ultimate outcome.
Theoretically you should use many gradations, however no sluggish extinction of
the sunshine textures with lowering battery capability.


Applicationsin automobiles

Mild textures can
be present in automobiles in lots of locations. Amongst different issues, they’re
used to implement indicator lights within the dashboard, outer mild caps
and headlights, inside mild bulbs, show, matrix, roll tape or
goal signal lighting. Oblique lighting is in fact additionally doable,
such because the lighting of spherical devices, buttons and switches or
the lighting of the rear registration plates on the automobile. These
will also be used to light up the inside. For the reason that automobile mild
in Omsi can’t create shadows, you can even create shadow results
with acceptable shadow textures.

The extra mild
variations you create collectively, the higher the sunshine within the bus
turns into. However desdo additionally the required quantity of labor turns into larger.
And this will turn into appreciable. However there are additionally
limits. These limits may be seen finest within the shadow textures. If
a number of mild sources shine on an object from completely different instructions,
the shadows forged and the illumination of the areas below the article
change. Right here, a number of completely different shadows may be created utilizing
textures, however there are some disadvantages: Omsi works higher with
fewer textures than with many and the hassle to set the completely different
shadow textures is out of proportion to the ultimate outcome.


Implementation of sunshine textures

The implementation may be very easy. On the one hand you want not less than two textures. When constructing objects in a 3D program, every object is supplied with a switched off texture (the so-called day texture). This could not have pure black (coloration code 0, 0, 0). By utilizing pure black, the article can’t seem vibrant through the day. A gray scale is enough. The second texture might have black areas once more, in order that the issues that ought to not shine later don’t shine. For instance a small field in black or a vibrant cease request indicator. All areas on the evening texture that ought to not glow later, such because the housing of a light-weight field, should be made black on the evening texture. So later solely what ought to glow, whereas the article physique itself doesn’t glow.

To create evening textures, it’s useful to make use of the day texture. This texture is copied and made black, however solely the areas that ought to glow later won’t be black. These later glowing areas are then illuminated and transformed to look as if they might glow. The one vital factor is that the illuminated areas don’t change their place within the evening texture, however keep the place they’re on the day texture. In any other case the place modifications within the recreation shall be seen later, which makes the textures twitch. However on the identical time you’ll be able to for instance show symbols inverted or change characters.

Lastly each textures are copied into the feel folder. If the article was inserted within the mannequin folder, you create the mandatory entries within the mannequin.cfg.

Pattern picture:

On the left facet you can find the each day texture. That is how the indicator lights are displayed through the day when the indicator lights are switched off. Herewith you’ll be able to assign a texture to 10 completely different objects. The identical texture exists twice. The fitting facet exhibits the feel a second time. That is used as evening texture. If the respective variable is energetic to activate the feel change, Omsi switches and the feel cutout on the correct facet is positioned on the article. It does not matter whether it is mild or darkish in Omsi, the utilized evening texture at all times glows, as a result of it needs to be designed as a direct mild. In case you would set it as oblique mild, you’ll see the impact solely at evening.

Texture examples come from the add-on MAN metropolis bus households from Chrizzly92 and have been barely modifi


Entry of the sunshine texture within the mannequin.cfg

These entries are additionally made shortly. Listed here are the usual instructions that management the feel change and two instructions that can be utilized optionally, relying on the impact you wish to obtain:

Entry within the mannequin.cfgDeclaration of registrations[mesh]
Object identify.o3dCommand that provides an object
File identify and file extension of the mannequin file[matl_change]
Every day texture.jpg

Activation variableCommand to do one thing with the feel
Texture identify and file extension, the day texture with which the article was mapped
Texture layer to be modified
Variable to activate the feel change[matl_item]Command that the feel layer needs to be modified[matl_nightmap]


Evening texture.jpgCommand that and how one can use the next mild texture
File identify and file extension of the evening texture

The remaining is managed by the script. If the variable to activate is 1, then the feel is modified. The entered variable then decides when the implementation of the lighting impact is used. Right here the applying potentialities are manifold.

The entered variable “zero” corresponds to the chosen texture layer.

[errorbox]Vital! The entered texture identify below the command [matl_change] MUST be equivalent to the file identify of the mapped texture

had been in settlement. In any other case the feel change won’t work and Omsi will report this error within the log file. This error makes

is noticeable in Omsi by the truth that many script variables now not work.[/errorbox]


Direct or oblique mild

To make an object glow straight, use this command:


This makes the sunshine texture very vibrant, so to see the glow even at excessive brightness (through the day in daylight). So the sunshine has its personal luminosity, as a result of you’ll be able to see the sunshine physique in a sure means. This may be discovered with mild sources with semi-transparent mild caps, akin to management lights or flashing lights.

If you wish to illuminate an object, i.e. obtain the impact that the article is barely illuminated (oblique illumination), use the command


With the command [matl_lightmap] it doesn’t matter if the feel of the sunshine space is snow white or has a coloured evening texture. As a result of right here the feel shouldn’t be modified, however the day texture is overlaid by the evening texture and brightened. This variant is helpful for not directly illuminated objects, akin to license plate illumination, goal or curler strips or spherical devices that aren’t backlit and never partially clear.

The distinction between the 2 textures is hanging. Whereas the direct mild texture [matl_nightmap] illuminates at evening in addition to through the day, the sunshine impact of oblique illumination is barely seen at evening. Through the day the distinction is hardly noticeable. In sturdy daylight, there may be hardly any noticeable distinction. At evening there’s a distinction once more. In comparison with the [matl_nightmap] command, the place the feel may be very luminous, the luminosity is far decrease with oblique lighting, with the [matl_lightmap] command.


Mild factors

Mild factors simulate the presence of sunshine sources that may be seen straight. In actuality, this corresponds to what you see once you activate a light-weight bulb when you can see the bulb straight. In Omsi, this makes the presence of a light-weight supply seen. However mild factors haven’t any additional operate in Omsi. Whereas textures are solely mild, mild factors may have an optical mild impact for the participant. So that you can provide a light-weight supply a sure Beldeffekt, which creates a light-weight corona for the viewer.


Benefits and downsides of sunshine factors

This listing may be very quick. You may make mild sources seen and you’ll put a number of mild factors in the identical place to create them with completely different depth and / or coloration. The massive variety of setting choices means that you can make the sunshine level seen in a sure route, to shine out of objects and rather more. Other than that this mild variant has no different operate in Omsi. It doesn’t produce any mild shine and due to this fact has no mild impact on objects.


Use of sunshine factors

In automobiles, these mild factors may be discovered in lots of locations, however primarily exterior the bus. One space of software is on the entrance of the headlights. A standard headlight can produce as much as three completely different vibrant lights. Parking mild, low beam and the excessive beam. Whereas the parking mild is finest realized with one mild texture, the low beam and the excessive beam may be realized with completely different mild factors. Nevertheless, because of this these mild factors don’t forged any mild on the highway. These mild factors solely have the aim to characterize a light-weight level.

Moreover, mild factors will also be discovered on the extra lights, hind lights and place lights. Contained in the automobile, you should use these mild factors on the inside mild (halogen spots, door lights, inside lights or indicator lights.

As a result of excessive variety of doable settings, the usage of a light-weight level may be very variable and can be utilized in many various methods. Additional benefits may be defined within the part Registration of sunshine factors within the mannequin.cfg. When such a light-weight level turns into energetic is once more determined by the variable whose state is calculated within the script.

Conversion of sunshine factors

Mild factors may be applied very simply. For this goal you solely should enter the sunshine factors within the mannequin.cfg. With the assistance of the given variable to activate, you’ll be able to management the sunshine level particularly. For a light-weight level there’s a command, as soon as with out and as soon as with a prefix.



The distinction lies within the variety of strings to be learn below the command. With out the prefix _2, the scope is smaller.

Vital observe! Mainly it doesn’t matter the place the sunshine factors are entered within the mannequin.cfg. However the mild factors must not ever be entered below [mesh]-entries with animations, in the event that they shouldn’t be animated. Since you can’t give mild factors a separate animation, it’s doable to assign mild factors to an entered animation. For this goal the sunshine factors are entered beneath the animated object. If mild factors are erroneously entered below an animated object, though the sunshine factors are alleged to be motionless, then the sunshine factors will transfer with it. Within the following instance, the sunshine factors of the hind lights had been entered below the steering wheel.

As these mild factors are entered below the steering wheel, use the

the sunshine factors not solely animate the steering wheel, but additionally

the article origin of the steering wheel, for the animation origin In

on this instance image the animation is unintentional. At others

examples, an animation could also be desired, for instance if

the hind lights are positioned on an animated tailgate, akin to

may be seen within the second instance image.

In any other case, the sunshine factors are entered below a non-animated object. For the non-animated object, the [mesh] entry should not have an inherited animation task [animparent].


Coordinate system in Omsi

The coordinate system in Omsi, is defined intimately within the article Blender: Import/Export 3D fashions.


Entry of sunshine factors

This part shall be considerably in depth. As a result of there are two completely different instructions to enter mild factors. The chosen command decides the quantity of settings. For simplicity, the lengthy command is defined right here.

[light_enh] with 11 following strings (traces to learn).

[light_enh_2] with 25 following strings.


  1. Place on the X axis
  2. Place on the Y axis
  3. Place on the Z axis
  4. Route on the X axis
  5. Route on the Y-axis
  6. Route-on-the-Z-axis
  7. Vector of the sunshine cone on the X axis
  8. Vector of the sunshine cone on the Y axis
  9. Vector of the sunshine cone on the Z axis

The reasons of the person strings (traces) now observe.


Place on the X axis

This defines the place the sunshine level is positioned in relation to the X axis (lateral alignment), referred to the middle of the bus. The X-axis extends from the entrance of the bus to the again and divides the bus right into a left and proper facet. A optimistic worth, shifts the sunshine level to the correct (entrance view) and all values are set in meters.

With a automobile width of two.50 meters, there may be one mild level that needs to be on the correct facet, so at most 1.25. A unfavorable worth shifts the sunshine level to the left. For this goal, the place worth is barely preceded by a “minus”.


Place on the Y-axis

With the second string, the sunshine level is positioned on the longitudinal axis of the bus. The Y-axis is in the course of the bus and divides the bus right into a entrance and a rear half. A optimistic worth shifts the sunshine level ahead, whereas a unfavorable entry shifts the sunshine level backward.


Place on the Z axis

The third entry then corresponds to the alignment of the sunshine level in peak. Nevertheless, the Z-axis shouldn’t be on the horizontal peak of the bus, however on the lowest level of the whole bus, i.e. on the lowest level of the wheels. Due to this fact, the Z-position of an object or mild level can often solely have a optimistic worth. If the worth is unfavorable, the sunshine level is beneath the highway.


Route on the X axis

The route indication, controls the alignment of the sunshine level to the automobile. Nevertheless, no diploma values of an angle are entered right here, however the alignment is entered as a variable with a hard and fast most worth. For the X-axis, because of this a optimistic worth aligns the sunshine level to the correct and a unfavorable worth to the left. Right here applies:

0 = no alignment on the X-axis

1 = most alignment to the correct (corresponds to 90°)

-1= most alignment to the left

Values larger than one are due to this fact not crucial. Nevertheless, values between zero and one are doable. To align a light-weight level to the correct entrance, the worth should be matched with the subsequent two strings.


Route on the Y-axis

On the Y-axis, the sunshine level is directed ahead or backward, akin to the Y-axis in Omsi. Right here applies:

0 = no alignment on the Y axis

1 = most ahead orientation

-1= most alignment to the rear


Route on the Z axis

As within the earlier two sections, right here the sunshine is aligned on the Z-axis in Omsi. The Z-axis corresponds to the alignment up or down. The next applies right here:

0 = no alignment on the Z-axis

1 = most upward orientation

-1= downward orientation

A mix of the three values for the alignment causes a direct change of the alignment in two or three instructions. To align the sunshine to the correct entrance, the alignment worth is about to 1 on the X-axis and 1 on the Y-axis, aligning the sunshine level to the correct entrance with a direct line of sight. Half values (0.5) can be utilized to attenuate this alignment. All different values from 0.1 to 1 are additionally doable to restrict the alignment of the sunshine.

Please concentrate:

The values of the alignment, correspond to the share values of an angle. The utmost worth 1 corresponds to 100%,

which corresponds to a 180° angle. A discount by half, corresponds to a price of 0.5 and thus an angle of 90°.


Mild cone vector on the X axis

With the alignment of the sunshine cone, the seen foremost route of the sunshine spot is decided. With the vector, the seen angular width of the sunshine spot is now outlined. Sadly, additionally right here no angle values are entered in levels, however numerical values. Whereas zero doesn’t specify an angle dimension, the one stands for an angle of 90° (100%) and the 2 for a most angle of 180° (200%). The essential route is given with the earlier values. The angle width may be set exactly with decimal values.

  • 0 = smallest angle
  • 1 = angle of 90°
  • 2 = angle of 180


Mild cone vector on the Y axis

The angles for the angular width on the Y axis are entered right here. The identical values apply as for the vector alignment on the X axis.


Mild cone vector on the Z-axis

The values for the angular width on the Z-axis may be entered right here.

Please concentrate:

The numbers right here characterize a proportion worth, the place one corresponds to 100% and two to the utmost

Alignment of 200%. Thus, the 0.5 represents an angle of 45° and the 1.5, akin to 150%, units the angle

to 135 levels.


Alignment of the sunshine spot

The above values decide the visibility of the sunshine spot from sure instructions. Nevertheless, if a light-weight spot needs to be equally seen in all instructions, the values entered above are all set to zero. The omnivector is then set to 1. This might make the sunshine level seen from all instructions that aren’t obscured by non-transparent objects. Right here, nonetheless, the rendering order of the bus personal objects should even be taken under consideration. If a light-weight spot ought to stay seen by means of a glass pane as a result of the sunshine spot is behind it, the sunshine spot should be entered in Mannequin.cfg below the corresponding glass pane. If, for instance, a door strikes over a light-weight level when it’s swung open, the glass, which is an Omsieigenes object, would cowl the sunshine level behind it. This limits the visibility. This has the benefit that the sunshine spot may be significantly diminished if the pane has a robust tint or the colour worth of the glass makes the sunshine spot virtually invisible or modifications the colour worth. For this goal, a primary mild spot is positioned above the mesh entry of the pane. To do that, you create a second mild level which is weaker and will get the corresponding change values. That is entered in mannequin.cfg below the goal. So with out the disc you’ll solely see the brilliant mild level that covers the darkish one and thru the disc you’ll solely see the darkish, modified mild level as a result of the disc filters the brilliant mild level. There are solely two values that may be entered right here. With the worth one, the entries for the sunshine cone route and the vector orientation are neutralized.

0 = Directed mild by the values entered above

1 = Mild in all instructions.


Rotation alignment

The rotation alignment is straight associated to the set values for the alignment of the sunshine level and particularly the vector dimension. Once more, there are three variables that management the habits of the sunshine spot in the direction of the digital camera (participant view).

  • 0 = The sunshine cone factors solely within the instructions of the set vectors
  • 1 = The sunshine cone rotates across the set vector axis within the route of the digital camera
  • 2 = The sunshine cone at all times seems within the route of the digital camera (sight view of the participant).


Coloration worth crimson

With the colour values it’s doable to pick the colour of the sunshine level. There are 16,581,375 colors to select from, starting from white throughout the whole color spectrum to the invisible color black. Nevertheless, solely the color of the sunshine spot is about, not the luminosity. That is additionally known as the color temperature. Thus, with the color values, one can emit heat white or additionally chilly white mild.

The primary coloration worth controls the colour depth of the crimson coloration, from 0 for no crimson to 255 for max crimson.


Inexperienced color worth

The second coloration worth controls the colour depth of the inexperienced coloration, from 0 for no inexperienced to 255 for max inexperienced.


Blue coloration worth

The third coloration worth controls the colour depth of the blue coloration, from 0 for no blue to 255 for max blue.

Collectively the three coloration values lead to a collection of over 16 million colours. So as to have the ability to set an acceptable color shortly, it’s advisable to set and skim out the RGB color worth with a picture processing program. Instance packages with hyperlink, may be discovered below file codecs used for Omsi.


Measurement of the sunshine spot

This doesn’t modify the sunshine depth, however solely the dimensions of the sunshine spot. The worth refers back to the dimension of the sunshine spot in meters. A worth of some millimetres corresponds to a single mild emitting diode (0.003, 0.005 and so forth.) or a transparent bulb. Values of about 5 centimetres correspond to a matt bulb. Nevertheless, it’s not doable to simulate fluorescent tubes or traces of sunshine with this, as a result of the sunshine spot at all times has just one spherical supply, whereas with a fluorescent tube the sunshine supply is at all times elongated.


Angle of the internal mild cone

Ranging from the sunshine level, you’ll be able to specify an internal angle for the sunshine cone. In an incandescent lamp, the sunshine level corresponds to the tungsten filament. The internal mild cone corresponds to the glass physique of the bulb. The set worth is reached at full mild depth. The angles are entered in levels.


Angle of the outer mild cone

The outer angle of the sunshine cone then determines the vary of the corona generated by the sunshine spot. The corona is an impact of atmospheric optics. The corona turns into notably seen when the eyes are very humid. For the reason that mild depth on a monitor is simply too low, a barely actual mild impact may be achieved and the sunshine appears to have a glare impact. Along with the adjusted mild cone vectors, the simulated mild depth may be prolonged to different surrounding objects. This angle can be indicated in levels.


Variable to activate the sunshine level

The variable refers right here to the script variable from the bus scripts. If the variable reaches the worth one, the sunshine spot is activated. If the worth is zero, the sunshine spot stays inactive. The right variable is decided from the scripts and entered right here.


Brightness variable

Right here the energy of the sunshine spot, i.e. the brightness, is adjusted. That is vital if a number of mild factors are on high of one another. This manner you’ll be able to simulate step-dimmed mild. The brightness is once more directed right into a proportion kind. So right here, zero corresponds to a particularly darkish mild (for instance that of a black mild lamp) as much as two, which corresponds to twice the luminosity, as for instance of a halogen highlight. Thus, values from 0% to greater than 200% are additionally doable.

0 = strongly attenuated brightness variable

0.5 = half luminosity

1 = regular luminosity

2 = double luminosity

*If half a light-weight depth is invalid as a result of the variable modifications too quick (stroboscope mild), then the fixed worth 1 is robotically assumed. Values above two, however, make much less and fewer distinction, as a result of 200% is definitely a most worth. With massive headlights, nonetheless, it could be crucial to extend the brightness barely. Values of greater than 3 are now not seen and due to this fact don’t present any distinction. The monitor shouldn’t be an energetic mild supply like a lamp. It’s due to this fact solely oblique mild.


Multiplication issue

With the intention to make a vibrant mild seem even stronger and extra radiant (high-pressure lamps or massive halogen lamps), a multiplication issue may be set right here. The upper the multiplication issue, the decrease the impact, as a monitor can solely produce oblique mild.


Offset worth to the participant

The offset worth of a light-weight level to the participant’s view (digital camera view) is the worth when the sunshine level is in an object, however the impact of the sunshine level ought to exit the article. If the sunshine level is inside a strong object (e.g. the sunshine bulb below a light-weight cap), this parameter can be utilized to make the sunshine level and the sunshine cones seen. If the radius is doubled, the sunshine spot will shine out of the cap. The sunshine cap doesn’t should be made clear. The route from which the sunshine spot is seen is about within the higher parameters. You possibly can, for instance, double the radius of the sunshine spot to the dimensions of the article utilizing a two. The decisive issue shouldn’t be the precise dimension of the article, however the ratio of the sunshine spot, how far the sunshine spot ought to shine out of the article.


Mild impact

Each mild produces a sure impact, the corona, which is often influenced by the attention moisture and a light-weight cap. This parameter creates the form of the sunshine impact (corona). There are 4 values that add as much as get each results.

  • 0 = no impact
  • 1 = Star impact
  • 2 = No fog impact (round corona)
  • 4 = each results collectively

The final parameter creates a round impact, barely overlaid by a star-like impact.


Mild cone

Each mild creates a cone impact if this impact shouldn’t be filtered below a matt mild cap. The cone impact depends upon fog and ambient brightness and provided that it’s not omnidirectional mild (see Alignment of the sunshine level in all instructions). So right here solely the values zero and one are doable.


Time fixed

If a light-weight level ought to slowly attain full mild depth, a time worth in seconds may be set right here. Particularly with older automobiles, the electronics turn into slightly sluggish. In case you set a price of 5 seconds, for instance, the sunshine spot wants 5 seconds to achieve an depth of 63%. The complete 100% is then solely reached with 7 to eight seconds. This corresponds to a light-weight that’s managed by a capacitor in order that the sunshine doesn’t out of the blue turn into vibrant like an LED. Thus, sluggish mild bulbs and even energy-saving lamps may be simulated. When switching off, it takes one other 5 seconds till the sunshine reaches an depth of solely 27%. The rise in luminosity is fixed.

The various older automobiles you’ll be able to see this impact very effectively with the flashing mild. The sunshine doesn’t exit fully, however solely turns into weaker and stronger once more.


Impact texture

With regards to the sunshine level, a texture (with file extension) will also be entered right here. This texture ought to have the form of the sunshine cap. So it’s spherical or sq.. Thus the entire mild physique seems illuminated. With a easy mild texture, which is illuminated by altering the instructions [matl_nightmap] or [matl_lightmap], there aren’t any mild results or sluggish switching on and off. There’s solely the operate on or off. Right here a easy mild texture is used which adapts to the settings of the sunshine level. All different mild level parameters are retained and are usually not misplaced when the feel is modified.


rotating beacons

Rotating beacons are an intensified mild impact. Which means that this mild shouldn’t be fully restricted by the restrictions of alignment, but additionally that it shouldn’t be seen from all instructions concurrently always. The viewing route of this mild ought to rotate round a hard and fast axis. To realize this impact, there are a number of potentialities, which can now be described.


Rotating level of sunshine

In all probability essentially the most troublesome variant is to offer the sunshine spot with a contradictory setting.

Below the purpose Alignment of the sunshine level the worth one is about, which signifies that the sunshine level may be seen from all instructions. On the identical time, the next level Rotational alignment of the sunshine level is about to the worth 2. The contradiction now could be {that a} rotating mild that may be seen from all instructions at any time doesn’t have to rotate, as a result of this rotation wouldn’t be seen. To stop the sunshine from being seen from all instructions on the identical time, the route that serves because the axis of rotation should be set to zero, as should the vector angles for the sunshine level.

  • X-axis = Alignment to the left or to the correct
  • Y-axis = alignment to the entrance or to the again
  • Z-axis = alignment to the highest or backside

Automobile rotating beacons are often positioned on the roof and rotate round a vetical axis to be seen in all horizontal instructions. So the alignment of the sunshine level on the Z-axis is about to zero, as are the sunshine cone vectors of the X- and Y-axes.


Flashing mild spot

If the above process appears too sophisticated, the sunshine level can alternatively be set in all instructions with parameter 1 below Mild level alignment. Within the script, the sunshine is then set to blink (for instance at one-second intervals) and the time fixed is about to half a second (worth 0.5). That is the way it was executed for the ambulances on the Spandau map. Even fashionable sign bridges of emergency automobiles work this manner. The stroboscope impact is created by a quick flashing. In case you decelerate this speedy flashing and management the sunshine in order that it shortly turns into brighter and darker, it seems as if the sunshine is popping.


Rotating object

The final risk is in fact the position mannequin. In a clear mild cap a vibrant spot of sunshine is positioned centrally. This could shine in all instructions concurrently. As well as, you create a mesh that rotates round this mild level (on the Z axis). The seen rotation impact may be intensified slightly bit when you give the facet of the article going through the sunshine a really vibrant texture. Along with an alpha channel, this floor can then be mirrored (just like a chrome impact). How this works precisely is defined intimately within the automobile SDK within the part Reflection Textures. The mirror impact is small, nevertheless it seems to be good.


Mild Shine

Since a light-weight level has no impact in Omsi, the sunshine should be adjusted individually. This separation of sunshine level and lightweight is because of the truth that Omsi separates bus personal objects and non bus personal objects. This separation is important in order that sure objects are solely illuminated by sure mild sources. In actuality there aren’t any variations. A light-weight supply illuminates all objects that the sunshine can attain. Both straight from the sunshine supply or not directly by means of reflections. In Omsi, nonetheless, this separation is important as a result of the sunshine in Omsi doesn’t take note of the form of the sunshine supply or the housing of the sunshine supply, or different objects. Mainly there are two kinds of mild. The sunshine for non-bus objects is named highlight. This highlight can solely shine in a single route and Omsi can solely entertain a single highlight. The spot mild is barely mentioned within the following part (part 1.5). This part offers with the sunshine for the bus personal objects, i.e. all objects which are on the bus and which are additionally entered within the bus personal mannequin file (mannequin.cfg).

This part, which offers with the interior mild sources, may be very in depth, as a result of there are dependencies in another recordsdata. As a result of the sunshine within the bus mustn’t solely illuminate some bus personal objects, but additionally tickets, cash and naturally the passengers. Omsi distinguishes between sitting and standing passengers who’re travelling with the bus, and working passengers who’re strolling by means of the bus or ready to get off. Meaning passengers who’ve reached a sure level and passengers who nonetheless wish to attain a sure level.


property and disadvantages

The sunshine can solely be energetic within the automobile that’s utilized by the participant. AI automobiles that ought to have a vibrant inside should be created with a LOD texture or a LOD mesh. The most important drawback of the sunshine is the interplay with different objects. A light-weight shines and thereby illuminates all object surfaces which are going through the sunshine. The brighter the feel of the article surfaces, the brighter the article seems. Sadly, that is the case for all objects that had been put in on the bus. It doesn’t matter if the sunshine hits the article straight or if it passes by means of different non-transparent objects. Which means that for instance the wheels may be illuminated by the inside mild, though the ground truly prevents this. An additional drawback is the shadows within the automobile that this causes. Whereas an object within the bus is illuminated, like a seat that’s illuminated straight, the world straight below the seat is illuminated with the identical brightness as the space to the sunshine supply. So the seat doesn’t create a shadow. In the identical means the backrest doesn’t create a shadow on the seat floor if the sunshine supply is in the back of the backrest. The driving force’s space, for instance, is illuminated by the inside mild, even when a non-transparent partition wall ought to truly forestall this. In fact, it’s also doable to separate objects from sure mild sources and to create oblique mild and shadows. On this case, you need to take note of how the sunshine ought to behave in a while, already throughout automobile building. This contradicts slightly bit what was described within the part automobile SDK below the tip about automobile building (exterior mannequin).

This massive drawback, nonetheless, is opposed by a particular benefit. The brightness of the objects decreases with the space to the sunshine supply. From a sure distance on the article is in shadow as a result of the vary of the sunshine supply is proscribed. This benefit can create very nice results in a bus. For instance, the door mild seems stronger close to the supply and weakens with growing distance. As well as, you do not have to create further textures to make this impact clear or seen. So you should use the sunshine to create shadow results. This may be achieved by working with completely different mild ranges.

Within the left image the floor of the money register, the money register mild and the door mild is illuminated. The stronger door mild, creates a slight shadow on the higher fringe of the money desk. The floor of the money desk is totally and evenly illuminated. In the correct image, the door mild is inactive and solely the money register mild illuminates the floor of the money register. The weak mild, decreases quickly with growing distance on the checkout counter. The door space is illuminated too weakly on this instance. If it had been actually darkish within the screenshot, the door space would solely be illuminated very barely.

One other drawback is the small variety of mild sources that may be assigned to an object. There are solely a most of 4 mild sources that may be assigned to an object. For some objects it’s simpler, for others this can be very troublesome, if there are 5 mild sources in actual distance to the article, however these 5 mild sources may be switched in another way.

One other level is the behaviour of the sunshine sources in the direction of the passengers in or in entrance of the bus. On the one hand, you’ll be able to set a variety of mild sources within the bus, which may have a very nice impact on the objects. As a result of you’ll be able to’t set the sunshine sources to the passers-by who’re shifting within the bus or ready to get off, too many mild sources can have a really unfavorable mild impact on these passengers. Passengers who’re sitting within the bus or have taken a standing seat for the journey may be assigned these mild sources once more. Since you’ll be able to’t assign these mild sources to the opposite passengers, ingame sadly additionally has some very disagreeable and unfavorable results, which may be particularly noticeable at evening. In case you cease a bus at a bus cease the place a passenger desires to get on, he instantly goes to the subsequent doable level of boarding. So long as the longer term passenger is in entrance of a glass door, he isn’t illuminated by the inside mild. If the door is opened and the door mild is switched on, the passenger shouldn’t be illuminated by this mild both. Solely when the passenger enters the primary path level of the doorway within the bus, he shall be detected by the 4 approaching mild sources and shall be positioned within the mild accordingly. This impact may be seen with a gaggle of boarding passengers in addition to with the group of disembarking passengers who’re instantly standing at midnight as quickly as they’ve left the final path level of the exit. If there are too many mild factors within the bus, passengers shall be partially mislit after they stroll by means of the bus. That is notably noticeable if there are path lights in a coach on the backside of the aisle. Since these could also be nearer to the folks than the ceiling mild, the legs of the passers-by are illuminated, however their heads stay within the shade, even when they stroll straight below a vibrant ceiling mild. However as a bus often has greater than 4 mild sources, that are additionally switched in another way, some difficulties come up. However these may be diminished by different means, which in flip means extra work. There are additionally some methods that can be utilized to scale back this drawback.

The sunshine sources that produce a light-weight beam are invisible. That is each a bonus and a drawback. Due to the invisible mild sources you at all times should set a light-weight level or a light-weight texture as supply. You must take care to regulate the brightness of the feel or the energy of the sunshine spot precisely, which isn’t simple. However, you’ll be able to mix a number of small mild factors and place the origin of the sunshine over the bus. This mild supply shouldn’t be seen, however the mild shines on the objects that needs to be illuminated by it. So you’ll be able to mix mild sources which are shut to one another, so to modify a number of mild sources to things.


Use in automobiles

In automobiles, mild sources that produce a light-weight beam are used wherever a light-weight supply is to light up objects and passengers. The interplay of the positions of the person mild sources, completely different brightness and the place in relation to different objects, can create a wonderful mild impact within the automobile. For instance, all ceiling lights in a bus should be supplied with a light-weight beam. Different objects may be supplied with mild factors as a supply of sunshine, which makes the sunshine impact higher than with a light-weight texture. So you will have the selection to offer the rear license plates with a light-weight and shadow texture or with mild factors as mild sources and with a light-weight shine on the license plate. There are a lot of examples the place mild shine can be utilized, akin to matrix lighting. These mild results are typically higher than mild textures. The creation of high-quality mild and shadow textures, however, may be very labor-intensive and requires good use of a picture enhancing program.


Conversion of the sunshine

The vary of strings (traces) to be set may be very clear and fairly easy. However please don’t be fooled. For a use you want one thing extra. However first it is just about creating the sunshine as a supply. Once more you begin with the command. The construction has a totally completely different order than all different mild factors. Instantly after the command, first the variable for switching follows and on the finish the place is entered:


  1. Variable
  2. Vary in meters
  3. Color worth crimson
  4. Inexperienced color worth
  5. Color worth blue
  6. Place on the X axis
  7. Place on the Y axis
  8. Place on the Z axis
  • The variable corresponds to the variable from the script when the sunshine supply needs to be activated.
  • The vary of the sunshine, signifies how far the sunshine depth reaches as much as 63%. The vary can’t be outlined precisely, as a result of the luminosity decreases constantly. So you’ll be able to attain white objects in 6 meters if the sunshine vary is about to 2 meters. However, objects with darkish textures don’t seem very vibrant when the vary is about to three meters. However these objects don’t seem black. Colored mild, has a distinct vary. So blue mild has a decrease vary than inexperienced or crimson mild, with the identical mild depth.
  • The colour values are to be set precisely the identical as with the earlier mild sorts
  • The place additionally corresponds to the settings of the opposite lights.

As already talked about, you’ll be able to set as many mild sources as you want. However what number of mild sources make sense, you’ll solely see on the finish, when the passengers stroll by means of the bus and the way the objects had been divided. This shall be mentioned in a later part. However the order of the entries is vital. You possibly can enter these mild sources within the mannequin.cfg the place you need. however the order is essential later. Like many different objects within the bus, the order is zero primarily based. So the primary mild supply entry has the sequence quantity zero, the second entry has the #1. When adjusting the sunshine sources it is best to observe the sequence. For a extremely good outcome, later within the automobile, you also needs to make a sketch. This makes the work simpler later, once you assign the correct mild sources to the objects within the bus.


Assigning the sunshine sources to things

To assign a number of mild sources to an object, there is just one command.


This command seems not solely within the mannequin.cfg, but additionally within the Passangercabin.cfg. For extra particulars, please seek advice from the article Passenger Routes in part 3.1.10 Mild Project.

That is adopted by a most of 4 mild sources from which the article is to be illuminated. These mild sources are then entered one beneath the opposite, whereby the task of the sequence signifies the numbering numbers of the sunshine sources. To make clear the entire thing I clarify it with an instance.

For example we take a easy automobile physique with two doorways, the place the doorway door is within the entrance and the exit doorways within the again. The sunshine above the doorways, which solely swap on when the doorways are open, is entered first. In order that they have the numbers zero and one. One other mild supply is positioned above the driving force’s seat and has as third entry the quantity 2. Lastly there shall be 3 extra mild sources, that are positioned as ceiling lights within the first third of the physique, within the center and within the final third of the physique. As these mild sources are in fourth, fifth and sixth place within the order, these mild sources have the quantity 3 for the entrance, 4 for the center and 5 for the rear.

Moreover we take the seats for the sunshine task. On this instance we assume there are 9 rows of seats within the bus and the driving force’s seat. Objects which needs to be illuminated by the identical lights may be mixed as one object. Within the instance, every row of seats is stored individually as a single object.

For the task of the sunshine to the driving force’s seat, there are already some restrictions. If there may be an opaque partition wall behind the driving force’s seat, the driving force’s seat will solely be illuminated by 2 to a most of three mild sources. Within the order by which the sunshine sources are listed, these are the primary door lamp and the driving force lamp. The primary ceiling lamp could also be added. Accordingly, the sunshine sources are assigned to the driver³s seat object:





Instance image, for the entrance ceiling mild within the Ikarus 250.59 coach.

Right here you’ll be able to see the distinction when the entrance ceiling mild is switched on and off. The hind lights stay on. The distinction is especially noticeable within the driver’s seat. The primary mild hangs proper subsequent to the curtain, with the facet of the driving force’s seat illuminated. And the entrance rows of seats are additionally illuminated.

The entrance door is illuminated by the sunshine sources of the primary door mild, driver’s seat and the 2 ceiling mild sources, as a result of there is no such thing as a opaque wall right here. So the task is:







Pattern picture of the sunshine separation:

For the rear door now you can take the rear door mild and the three ceiling lights







There are numerous potentialities for the rows of seats, relying on the structural circumstances. Whereas the primary two rows of seats are illuminated by the door mild and the ceiling lights (following instance on the left), the driving force’s mild can illuminate the rows of seats on the door facet, however not the rows of seats behind the driving force’s seat (following instance on the correct), if an opaque wall has been put in. For this goal, the primary two rows of seats also needs to be separated for the respective sides.

For the row of seats on the door facet, the sunshine sources 0, 2, 3 and 4 can be utilized; for the doorless facet behind the driving force’s seat, the sunshine supply (2) for the driving force’s seat (0, 3, 4, -1) shouldn’t be used.


Right here you’ll be able to see the distinction when switching the entrance ceiling mild and the driving force’s mild. The impact is intensified by the truth that the remaining lighting is inactive. This instance finest illustrates the distinction between accurately divided rows of seats. Whereas the entrance ceiling mild illuminates the primary rows of seats behind the driving place, the seats stay at midnight when the entrance mild is lacking and solely the driving mild is energetic. The primary row of seats on the door facet, can be illuminated, however is barely barely lit by the space.

The rows of seats on the doorless facet are illuminated solely by the entrance door mild, the primary ceiling mild and the entrance mild circuit. So there are solely 3 mild assignments for these seats. The fourth mild task is excluded by -1.

As a alternative, you should use the second mild circuit, which may have a unfavorable impact as a result of it’s distant and the backs of the seats on the doorless facet may seem brighter than the seats on the door facet that aren’t illuminated by the rear mild circuit.

For the third and fourth row of seats the three ceiling lamps are typically used. Optionally, the primary door mild may be added right here (0, 3, 4, 5). For the seat rows 5 to 9, as an alternative of the entrance door lamp, solely the rear one is assigned (1, 3, 4, 5).

Instance for the center and rear mild circle. Each mild circuits are switched alternately right here. With the right allocation of sunshine, there’s a clearly seen interplay on the seats.

Nevertheless, the task doesn’t should be rewritten for every row of seats, as a result of the command [illumination_interior] stays legitimate for all following objects till it’s modified by a brand new task.




















Alles anzeigen

On this instance sequence, objects A, B and C are illuminated by the sunshine sources on the primary door, the driving force’s seat and the entrance and center ceiling lamps. The article D and all following ones are detected by the second door mild and the three ceiling lights.

If an object is to be detected by lower than 4 mild sources, the remaining digits may be written with -1, or the above numbers may be repeated. Nevertheless, this doesn’t change the sunshine behaviour on the objects.

Instance of entrance and rear door mild.

For the reason that mild shines by means of objects, the wheels, for instance, would even be illuminated. To exclude this, a light-weight task with out mild supply quantity is created.









Nevertheless, if an object is to be illuminated by greater than 4 luminaires, this isn’t doable. For instance, the ground can’t be illuminated by all mild sources if the whole ground is used as a single object within the bus. That is the place it is best to minimize the ground. The identical applies to the whole inside of the physique.

Pattern picture for full illumination. Right here the completely different mild circuits are switched by means of one after the opposite.

Allocation of the sunshine to passengers

These mild sources want solely be assigned for sitting and standing positions. For this goal the identical command [illumination_interior] is written below the locations within the passengercabin.cfg No assignments should be set for passengers strolling by means of the bus or ready on the bus (for instance, ready for a free ticket workplace, free canceller or for getting off). Driving prospects deal with the 4 activated mild sources which are closest to them. A extra detailed description may be discovered within the article Passenger Routes.


Allocation of the sunshine to cash and tickets

A particular means of sunshine allocation is the cash given by passengers, tickets and alter. These objects are usually not entered within the mannequin.cfg. The article recordsdata and textures are positioned in separate folders and the positions are entered in different recordsdata. The positions for the issued tickets, in addition to the passengers’ cash and the given change, are entered within the file Passengercabin.cfg. The sunshine task instructions don’t apply to those objects. The positions of the tear-off blocks (for giving tickets) are written to the bus file. However there a light-weight task shouldn’t be acknowledged.

For this OMSI takes over the sunshine task of the final object from the mannequin.cfg. Accordingly, the final object needs to be an object that’s positioned on the identical place. You possibly can enter the money register final or one other object that’s illuminated by the identical mild supply. Alternatively, you’ll be able to select an unlit object that’s positioned so removed from the sunshine sources that it’s not illuminated, or whose object surfaces are averted from the sunshine. This object is entered final and will get the sunshine allocation for the cash and the tickets.



The highlight is a light-weight that produces even a single beam of sunshine. However in distinction to the sunshine for bus objects, the highlight is just for non-bus objects and illuminates all surroundings objects akin to streets, homes and different map objects which have been put in, but additionally the passers-by and all AI automobiles in circulation. Nevertheless, there may be additionally a serious drawback. Omsi can solely create one single highlight within the recreation. In actual life, headlights produce a light-weight beam, not solely from your personal automobile, but additionally from all different automobiles. In the identical means, tail lights, brake lights, indicators or reversing lights additionally produce a light-weight beam. Solely the automobile you drive your self may be outfitted with a spot mild. Moreover, you’ll be able to solely specify one route and one coloration. In case you would give the hind lights a spot mild, you would need to do with out the entrance spot mild. However because of this the highway in entrance of the automobile is now not illuminated.

However within the mannequin.cfg a number of spotlights are set. For instance, there’s a spot mild for the low beam with a decrease brightness and vary. The excessive beam will get one other level for the spot mild, is then brighter and has an elevated vary. Additionally it is doable to set further spotlights within the entrance. This permits the usage of further spotlights that combine auxiliary and fog lights. These should then be adjusted to incorporate the person or mixed switching choices. These particular person spotlights shall be defined in additional element in a second.

Once more, the order by which Mannequin.cfg is entered is decisive. Afterwards the corresponding spot mild may be activated.


property and disadvantages

As already talked about, you’ll be able to solely create one spot mild in Omsi at a time. That is the largest drawback of spotlighting. You possibly can once more set a number of variants. In Omsi you’ll be able to swap by means of these completely different spotlights one after the opposite, so the entrance mild may be designed in another way, relying on whether or not you turn low beam, excessive beam, with or with out auxiliary headlights. The order is outlined within the mdoel.cfg and set within the script. How precisely this works shall be defined intimately in a second.

AdvantageDisadvantagesMany setting optionsOnly a single spot mild may be usedDifferent spotlights may be switched by means of one after the otherOnly seen on the present participant vehicleindependent of different lights and objects.Highlight doesn’t create shadows.


Changing the highlight

The settings are very simple and shortly defined. First the command follows once more, adopted by 12 strings (traces) which obtain the corresponding values.


  1. Place on the X axis
  2. Place on the Y axis
  3. Place on the Z axis
  4. Alignment on the X axis
  5. Alignment on the Y axis
  6. Alignment on the Z axis
  7. Color worth crimson
  8. Inexperienced coloration worth
  9. Color worth blue
  10. Vary of the sunshine
  11. beam of sunshine inside
  12. outer cone of sunshine

Right here too, the person strings are easy and clear. The primary three traces outline the positions within the bus. Since there is just one spot mild, it’s not doable to create it for 2 entrance lights individually. So a spot mild in the course of the bus is outlined and set (X = 0). The Y worth needs to be on the entrance of the bus. This shouldn’t be too far in entrance of the bus, but additionally not too far contained in the bus. If it’s not positioned far sufficient ahead, the highlight illuminates the shadow of the bus, below the automobile and exits along with the bus. Set too far ahead, the sunshine will seem flawed. The identical applies to the peak. Set too low, it doesn’t illuminate the road correctly and the sunshine falls off polygon by polygon. If set too excessive, the highlight seems to be faux once more. It ought to due to this fact be about 50 cm to 1 meter above the headlamp degree.

The alignment is easy. For the reason that mild mustn’t shine sideways, the X-value for the alignment is at all times zero. For the ahead route, the Y worth is at all times set to 1. The Z worth may be adjusted in accordance with the switched mild. For the reason that dipped beam mild mustn’t shine too excessive, the Z-value of the alignment is about barely downwards. A unfavorable worth between zero and one is about. Zero signifies that the spot mild is shining straight ahead, the worth -1 signifies that the sunshine is tilted downwards. A worth of about -0.3 is finest for this. This worth can nonetheless be adjusted slightly bit. For the reason that foremost beam shouldn’t be restricted, the angle on the Z-axis needs to be smaller right here than on the dipped beam, or set to zero.

The color values are once more set in color in accordance with the opposite lighting choices. Halogen lights shine barely yellowish, xenon lights shine white and LED lights shine barely blue.

The vary of the spotlights once more depends upon the kind of mild switched. Dipped beam alone has the smallest vary. The data shall be entered in metres. A worth of 200 meters needs to be enough. Dipped beam with auxiliary headlights, such because the entrance fog lights, however, will get a barely increased worth. About 300 to 350 meters needs to be sufficient. And the excessive beam will get the longest vary, with 500 meters being real looking. Right here it doesn’t matter whether or not the fog lamps are switched on or not, as these are often beneath or on the identical peak as the principle beam headlamps. However the illumination modifications.

The final two values are the illumination of the spotlights. There’s an internal circle that illuminates the principle a part of the highlight. This worth needs to be decrease than the exterior illumination. It means how far the highlight falls out to the facet. Decrease values are acceptable for the low beam and excessive beam, and better lateral illumination is acceptable for the spot mild with auxiliary headlights. These are then entered in angular levels.

These had been already the settings for the highlight. Since these entries do not need a switching variable, the variable (S.L.Spot_select) is assigned a numerical worth within the script. If the numerical worth is beneath zero, i.e. the worth is -1, then no highlight is switched. Since Omsi begins the numbering order with zero, the primary entry of a spot mild, the spot mild, is 0, and all additional entries improve by one digit. With additional variables the worth can then be additional elevated till all spotlights may be switched. The variable Spot_select shouldn’t be mounted on the Omsiside, however continues to be one of many mounted Omsi variables. The [Spotlight] command is unchangeable and solely one among these command sequences may be learn out at a time.

The implementation of the person entrance lighting can be easy. Within the Mannequin.cfg the spotlights are entered one beneath the opposite. In most buses, the primary entry is for top beam and the second for low beam. For this goal, the variable (spot_select) is about to the worth zero – for the primary entry, or to the worth one, which stands for the second entry.

The next applies to the excessive beam: most vary, common lateral illumination and direct ahead beam. For the dipped beam mild, these values are barely adjusted: lowest vary, not so vibrant, directed barely downwards and smallest lateral illumination. After that you could enter the spotlights for the entrance lighting with the extra headlights. The next applies to foremost beam with auxiliary lamps: most vary, highest lateral illumination, directed straight forwards and most brightness. For dipped beam with auxiliary headlamp, the next then applies: medium vary, medium to excessive lateral illumination, not so straight ahead and medium brightness. In order for you, you can even add the auxiliary headlamp, a separate highlight entry, which then works with out dipped or foremost beam and is barely switched with the parking mild or with out parking mild.

Object illumination

Since Omsi, alone solely the participant automobile accurately in mild, the sunshine is ineffective for AI automobiles. With the variables, you’ll be able to activate the sunshine objects, however all objects stay at midnight. If a participant sits down as a passenger in a automobile with inside lights, the inside lights are reactivated, which additionally makes the lights work. Now you will have the chance to light up the inside partitions and seats with mild textures, however provided that the textures weren’t tiled onto the objects. The quantity of labor concerned may be very massive. However this makes the lighting within the bus look actual and appears very real looking.

The opposite choice is the article illumination. The objects within the bus obtain the command [matl_allcolor] with 14 strings. Thus the objects within the bus seem illuminated, however have the drawback that the objects are typically illuminated and are usually not aligned to the sunshine positions. The sunshine vary can be ignored right here. Nevertheless, the drawback shouldn’t be vital right here, for the reason that lighting impact can’t be exactly acknowledged in AI automobiles anyway. With out this entry within the mannequin.cfg, the inside stays darkish, regardless that the AI bus has activated the inside mild.


property and disadvantages

The article illumination takes no account of the particular place of the inside lights. The objects are solely illuminated generally, in order that they solely make sense in AI automobiles, or if there are extra mild factors than may be assigned to the objects. In participant automobiles the article illumination can be utilized when you’ve got a big circle of sunshine and the inside needs to be fully illuminated. This makes the lighting habits within the automobiles look very unrealistic. Solely by working along with the sunshine sources and assigning the sunshine to them can a suitable mild behaviour be achieved.

– tabelle fehlt/folgt


Lightening operate

In Omsi, when the pure mild is lacking within the recreation (sundown or solar is obscured by a thick cloud cowl), objects are now not illuminated. These seem darkish on the bus. With the command [matl_allcolor] the colours are restored. Other than that, you may make objects in different colours glow or shine.
