I plan to do some more renders and I am trying to figure out how to correctly blend detail maps. It seems there are 2 detail maps blended together using a mask and this is then blended with base texture using roughness map (normal bump and diffuse channels). I dug around internet for some documentation, but had no luck. I am doing tests with different environments to see if the render matches ingame.
