The only thing I could find was painting the weights manually, which is extremely tedious and prone to missing verts. Is there a flood function somewhere?
For instance, do any of these correspond to the Transparency Add Shader? (in which case I'm assuming I maybe could start by duplicating it's function? )
The issue in question here was due to using a "portable" copy of Photoshop. Quixel SUITE requires a standard installation of Photoshop in order to function correctly.
