Substance painter to Marmoset Toolbag 3

OccultMonk

I can't seem to find the best export preset for Marmoset toolbag 3. There is a Toolbag 2 export guide, but not for toolbag 3. Is there a certain existing preset, or best export settings described somewhere?

The only significant difference for Toolbag 2 to Toolbag 3, in terms of the material system, is that Toolbag 3 uses the GGX Reflection model by default. I'm not sure what sort of options you have in Substance Painter, so it might be better to ask this question in the Substance forum.
