I noticed your sketchfab asset has normal, roughness, and metalness maps. I am curious how this is usually done in the game pipeline. Did you somehow generate them from your color map? Did you hand paint them like in the tower defense course? I see lots of hand painted stuff on sketchfab with fancy normal maps and I am not sure the best way to go about generating those maps. Thanks!
Hey John,
For this I used Substance Painter, which is a pretty common texturing tool. If you want to check it out in a game pipeline, I'd recommend these two courses:
