Made this so we wouldn't have to spend time in class pointing out who did what.
There's probably several faster ways to do it, like having everyone put something in their own materials or renaming all of their files to work with some code*, but this was all I could make without editing other people's stuff.
*Tried this. Unreal keeps a reference to the old name, and for some reason uses that when playing, so the code only works with meshes placed after the name was changed. As far as I can tell there's no way to delete the history of names.
