It does it under street lights too?
What software are you using to edit the cars?
What shader are you using for the body?
It's only the car paint, the rest are fine?
So, maybe your custom shader doesn't support external lights correctly.
Are you sure that problem is caused by headlights nor by track night lights?
U're right.
Then please paste your headlight projector definition.
Projector=Headlight
{
Moveable=True Active=False Pos=(0.0, 0.10, -75.6) Dir=(0.0, -0.5, -1.0) Radius=(28.0) LODOut=(350.0) Blend=(InvDstColor, One) Dyn=True Texmap=HEADLIGHT_.tga
}
Looks good. I was afraid about Blend options.
YW, I think I found the problem with the upgrades, did you see the other thread?
