When modeling car optics do you have to make the glass thick or is it
enough to just have one sided polys that is seen from the outside?
Is this depending on application/renderer or is there any general rule?

Ive started modeling this headlight and as it is now I've thickened the glas pieces
(as seen in the two top pictures), is that good or bad?
I will then use a bump to mimic the glas structure stripes.

Please leave some C&C!

I would thicken it. Whenever I model glass or plastic of any type, I make it thick as it normally would be. But you could leave it flat and use a bitmap to just represent the light, but I think that lessen's the realism sometimes.

definitely thicken!
makes your life much easier for refraction, and the general rendering. fake thickness can work, but if you want realism, thicken it!

Thx guys :)
So i will go for thick glass then and probably uv map the inside to put a bumpmap on for the kind of stripes you see in headlights on most cars.
