View Full Version : Tail Lights- Vray

05 May 2008, 04:13 AM

I'm currently doing some tests for my car tail light, and

I'm using a sub object material and setting the front of the tail light glass as the color without a bump map, then the back has the color with a bump map.

However when I render it, I'm not getting any bump look at all.

If i set the entire thing to the "color with bump map" I get the effect I want.

So can anyone look at my file and see if I'm doing something wrong?

Thanks! (

in the file, you can go to the material editor and find the "tail light" materal, its a Sub object material.

heres a test render with just the bump material on the back (

and heres a test render with the bump material everywhere, not using the sub object material (

here's the method I'm trying to use (found on another fourm)

Does the material render both sides of the faces? If backface culling is on for this material, the polygons facing away from the camera would not be rendered.
