I often struggle with bumpmaps in rt gpu, especielly with refraction envolved.
Here I use a noise map to create som surface bumps in a window.
The GPU render however is very different from CPU and vray adv.
Noise map uses UVW mapping. Baking the noisemap doesn't help either.
What i don't understand is that bumpmaps often work great and sometimes they don't it seems.
