Vehicle lights uses use a second RGBA mask texture where from which each channel from RGBA color space defines a luminance mask for a particular type of the light:
* R - left blinker, right blinker
* A - positional
Second The second requirement for vehicle lights to work properly correctly is to use a separate UV layer for the lamp mask texture and proper tile offset of the mappings. Tilling Tiling is applied on the right side of the texture in the following order:
# <ol start="0"><li>original texture - front left side of vehicle</li># <li>first texture tile - front right side of vehicle</li># <li>second texture tile - rear left side of vehicle</li># <li>third texture tile - rear right side of vehicle</li># <li>fourth texture tile - middle of vehicle and DRL</li></ol>
== Auxiliary lights ==
There is also possible to use two different colors for auxiliary lights with offsetting UV mappings for second mask texture. Tile offset here is also done on the right side of the texture:
# <ol start="0"><li>original texture - white color</li># <li>first texture tile - orange color</li></ol>
== Traffic lights ==
Traffic lights don't use extra second mask texture as they are using alpha channel of base texture for proper lit of traffic lights. But they still use tile offset on UV mappings to properly lit up different color in traffic light. Tile offset here is done on right up side of the texture in the following order:
# <ol start="0"><li>first texture tile - red color of traffic light</li># <li>second texture tile - yellow color of traffic light</li># <li>third texture tile - green color of traffic light</li></ol>
