This is the "best-kept secret" in 3D. You can buy a perpetual license for Substance Painter on Steam. It’s a one-time payment, and you get updates for a full year.
If you’re referring to a cracked or pirated version of Adobe Substance 3D Painter (e.g., via “GenP” — a patcher for Adobe software), I can’t provide instructions, links, or papers on that topic. Using or distributing cracked software violates Adobe’s licensing terms and copyright laws, and it also carries security risks (malware, lack of updates, instability). substance painter genp exclusive
