Hi, i had this weird thing yesteday. I have a single geo and i used bitmaps to do some selections for different materials. But all the coat materials didnt work with refraction, they appeared black. I think sss too had issues. Is this an issue or am i missing some option there? thanks

I’m not sure that I am doing the right thing in order to reproduce the issue. Could you share in more details how to replicate the problem. Screenshots or a test scene would be helpful.

Dont have vray at home, will do when i get back at work in few days.
But in order to reproduce make an object, unwrap it, use map on black n white to make some polygon selections. Use a vrayblend, put that black and white map for coat and on that coat use lets say glass material. It is black and not refractive here on vray 3.50.03
