How to make your rotary lightbars glooow~~~ or spicing up your retro vehicles' visual appearance. See the attached video for direct comparison.
To achieve this beautiful effect, a couple of edits are done to the vehicle's sirensetting in carcols.meta. No model edits are needed. Works fine for vehicles that combine halogen/strobe and LED lights.
Per-siren settings:
intensity = 40-70
^ Ramping this up does all the magic. We usually set this to range of 0.5-2, but with these values there isn't enough power to induce that beautiful inner glow in glass shaders.
All sirens that don't belong to the rotary lightbar have to have their intensity increased as well!
spotLight = true
^ Can be set to false for a single siren to add static glow effect, works kinda well for lightbars with many rotators.
Coronas can also be made smaller so that they don't obstruct the glow. I like:
size - 0.2-0.5
intensity - 35
Global settings:
textureName - distant_light
^ This one works the best of all available vanilla textures, imo, giving a nice round cone of light with soft edges.
lightFalloffMax = 100
^ Higher than usual for rotary lightbars. Is that way because, with lightFalloffExponent being way up, light power drops with distance more quickly.
lightFalloffExponent = 150000
^ Has to be that high to compensate for insane brightness of individual sirens.
lightInnerConeAngle = 125
^ Barely noticeable, can be neglected. Adds slight soft light cone around the main one.
lightOuterConeAngle = >45
^ Decreasing this can move light cone out further from your car to minimise lighting up the ground under the car, but will also decrease the power of glass glow effect of every rotor.
