I've always wondered if this was possible to do but never looked into it myself. Never heard of the program Substance Painter until now. I wonder if there's an alternative program out there that's free or cheaper? I've never been skilled at working with 3d programs but i'd be bound to try to learn if I could paint on presets like this.
Anyway, thanks for bringing this to my attention. This greatly ups the preset making game xD. This could save me a lot of time if I ever looked into using it or finding an alternative.
