aeScripts has a new plugin available that will let you take a UV or ST map (texture coordinate map) from your 3D Package of choice, and use it to retexture models in AfterEffects.
The process is simply enough, stretching and warping the texture to match the desired UV or ST coordinates, but opens up a lot of capabilities in the final stages of compositing. Things like rendering a blank car model with the UV map, then using AfterEffects to map multiple color schemes or paint jobs onto it.
