Unfortunately there just doesn’t seem to be a lot of love for Linux when it comes to some of these texturing packages.
The only real two I’ve been able to scope out are Substance Painter on Steam, which can be somewhat expensive.
Another option is ArmorPaint, which is a simpler texture painting app that could potentially work. I think tutorials on this software are fairly sparse, but from what I’ve seen there have been some cool textures created using it!
