Hello!
I've been using Substance Painter since I picked it up on Steam a few years ago with Substance Painter 2. I love this program so much! Thanks to the team for basically bringing together what I like about procedural creation and Photoshop and basically making it into one comprehensive program.
However - Substance Source doesn't ever load. When I open it in Painter, I just get the S with the animated dots, but it never actually loads or does anything.
It sounds like a cool thing, I'd really like to try it out.
