Welp i'm not very good at this nor is photoshop the best 3d painting program there is, but there we go
I really didn't put any time into it, just took a few grunge brushes and slew them about, which means that things got kind of shaite as it's just projecting, but hey, the concept works, although you'd want to find a better 3d painter than photoshop, since it seems to be a malformed feature stuck on for the sake of marketing
