Here is my Audi DTM model. I have it set up correctly for the renderer cycles.
It took me some time to understand how it works in cycles-renderer
with the uv-maps, texture maps and alpha maps. This is my result. I hope one or the other, this helps
something in dealing with the new render engine Cycles.
