I have some textures that I bought some time ago. If I want to sell it, should I inform the creator of the texture or do I need to ask permission from them?

As far as I know, you can sell them for as much or as little as you want. You paid good money for them and thus they become yours to own, use and sell. You do not need to report or ask permission off anyone.

selling questions confused PIEEE
