Substance Painter Lookdev: A better way to export roughness texture maps for artistic control.
Substance Painter exports specular roughness maps by baking the roughness values into the pixels of a greyscale texture map. This has the advantage of giving variation in the roughness across the surface, but the disadvantage that the roughness slider is replaced by the map, thus losing artistic control in Maya. This video demonstrates an improved workflow in both Maya and Substance Painter that avoids this trade-off, providing both variation and artistic control by creating a setup with two roughness sliders in Maya driven by a mask.
