It was rambly, but here are the questions I see: Where do you get your textures? *confusing sentence about handpainted textures he... didn't handpaint?* Is there a known legal stock texture that I could use for a piece?
I think he means he took a handpainted texture and applied it to a mesh. Something like this maybe something he didn't paint and applied it to a sword he built. which is not cool unless it was painted specifically for that purpose.
