Thank you . So about that roughness map thing, I use Awesomebump to generate the roughness maps form my texture, the problems are, Awesomebump gives me three different roughness maps: Color filter, none and noise filter, here is a screenshot
. I’m not sure which one should I use. Also in UE4 editor, do I just simply plug one of them in the roughness node? I see each map makes the rock very shiny and polished in the result.
