This belongs in the Marmoset section rather than Technical Talk, moving it for you.

marmoset 2 uses blinn-phong as its default reflection model. I belive painter uses GGX.
also Painter uses roughness map while marmoset uses gloss, which is basically an inverted version of the roughness map.

Hope that helps!
