First, are there any free texture packs out there? I can find texture sites of course (although most of them seem to ask for “credits”), but is there any decent pack with preferably seamless textures?
Second, is there a free tool that creates PBR materials? Or non-free at least. I know that there are 1 or 2 online sites that do this for normal maps and bump maps, but I don’t know if there is a simple offline solution, I suppose that Substance painter (or the other one?) does this, but I haven’t looked much into it yet.
