PBR Wood Roughness Texture
Hey guy,
Had a quick question about roughness maps for wood. I've tried using the Microsurface Value for wood from the material value chart on the marmoset site, but it always comes out too glossy/shiny. I lighten it up a bit and get a better look but still have a little trouble going about getting a good roughness map for a lot of my assets. Any good tips or ideas, or maybe good places to look for good information on roughness maps other than the marmoset site. Thanks for the help!

In Unreal Engine 4, a black value is actually full shiny and a white value is very hard/rough surface. Marmoset works in reverse.
Or, if you don't want to do this step, you can just use Dontnod's chart. The values are already UE4 compatible.
