Hey,
right now I try to create a landscape for my game. Everything is fine with normal materials BUT I tried using Substance materials with the plugin. I added the Substance material to the Layers section as u can see on the left of the screenshot.
But after painting with it, it loads some shaders, then it shows the material for a few seconds on the landscape. And after those few seconds the complete landscape just gets unpainted.
I really hope someone knows an answer, because I´d love to use the Substance material. They look really good.
