I mean 1 minute as in “start the level tools, select the content, note the name, find it in the revision tracking software, have a talk with the person that submitted it”
It’s not like someone can sneak stuff into a game without trace. I have a hard time buying that a big studio is not using perforce or something simillar to make the games. It takes 1 minute to check revisions and give when those things were added and who added them.
