View Full Version : How to Model Headlight / Turn Signal Lens Geometry?

09-11-2013, 02:37 PM
Does anyone have any good ideas or shortcuts for how to model a car's turn signals and headlights? I'm guessing the best approach is to model the actual geometry and then use radiosity, but that makes for some really long render times and I'd like to animate the car that I'm making.

Are there any shortcuts or ways to fake the lens geometry to make it look close enough to what you'd get with actual geometry? (or at least good enough that it wouldn't be noticed in an animation) How does everyone else deal with this problem?

For your purposes, cheating might be a better option. Check out some of the free models that this member has provided.


He has sometimes mapped photo textures to these kinds of lights and for moving animations it would be acceptable I think.

His free models have appeared here and might also be found at Lightwiki or Benelux, or on his blog.

Otherwise it's as you say, modeling the geometry, combined with normal maps.

EDIT-some of the ideas I illustrated in that other thread I no longer do that way, I tend to keep it like the real thing now.
