So in the early days, I thought I needed the Unreal Engine AND the UT Editor. Have since deleted the engine files since they took up such a huge amount of space. Anyway, I want to make sure my folders are intact for the editor and game. What made me think to check this is that "bug" where some community maps run without any materials on the Mac. I was thinking it might be because I have messed up the circle of life inside the UT world. I guess I could just delete everything and download fresh, but wanted to ask first.

Thanks for any info.
