Thoretical Copyright Question

[skirtboy]

If I were to use screenshots of a commercial game such as The Sims 2, using only third-party textures and objects, which I have authorization from the creators to use, to make (for example) an RMXP tileset, would that be a copyright violation?

Probably, although I'm by no means an expert on the subject.

Probably, but no one's gonna care unless you try selling it for money.
