Hi guys, I need some help for texturing a car headlight for a game model using PBR shader, I dont know how to do that, I just have the color that I want a "guessing" roughness value and an emissive color. What kind of texture should I put on it on basecolor and roughness ??? does the emissive color have to be just a flat color or can I work with some variations and/or blend a cavity map ??? for transparency, as far as I know U4 doesnt support roughness input with opacity masks, so do i do a opacity mask or not ?? sorry for so many questions.
