Hi, Is it possible for a guy who know nothing about PBR can make some contribution. I mean I really to help but I don't know where to start.

can you try brutal doom 21. It contains dynamic light sources and its own brightmaps.pk3 and lights.pk3, so it will be easier to see the effect. You should also use doom 1 or ultimate doom as this mod doesn't cover doom 2 texture. And how did you create the pk3 file? Did you compress the whole folder "materials" or its subfolders?
