Completely black or white roughness/albedo/metalness in texture bake

Cirmius

So I tried to bake textures using MT3. I've used it for baking normal maps, but I want for now to bake metalness, roughness and albedo.

Marmoset bake the normal map perfectly, but the other textures are completely black or white. I have no idea why. I tried with different samples, format (.tga/.jpg/.psd) and the result is always the same.

Ok, I coped with that. It seems like when you have plugged metalness map, Marmoset has the same issue as Blender in baking texture maps. You just need to unplug metalness and the program bakes everything perfectly.

I believe this was a bug that has been fixed in Toolbag 4.
