Hey John, that’s a good suggestion! We’ve got the exercise on painting an ax, which covers the basics, but a more in-depth course would be cool. I can’t make any promises, but I’ll put it on our list.
That said, we do have a wealth of courses that touch on texture painting – if you don’t want the other PBR maps, then don’t paint them. It just makes it easier while the technique is the same!
