If I’m reading this right I can’t use this in a game I intend on selling if I buy or get them for free from the market place? My main area is gametextures.com, but a question in case I do actually get something else (paid - ex: weapons) would be nice to get an answer on as well. I have intended on using gametextures for a while now, but I’m not at the point where I feel the need to have correct textures. If I used any of those textures in my game rather than going through gametextures directly it won’t work?
Just trying to clarify this (free and paid content) as I’m not a legal expert on this subject.
