I finally made some progress in learning some more of Substance Painter, which was what I was after from the beginning.
(These images were screencap'd from within Substance Painter.)
I was already super impressed with the Substance software, but after a few hours of using them... I have to say, I am a fan for life!
I'm still focusing on texturing, I want to add a few more subtle scratches on the chess pieces and on some other areas of the chess board.
After exporting the new textures from Painter, I'll work on some final edits within photoshop, and then back to Unity for some lighting and material work.
