Yesterday, I imported a bunch of models into my map, and I tested them all before I created new ones, but today, almost all of them now appear as green/black boxes. Most of the heroes still show up, but some of them don't. I followed what the directions said, renamed the files to what they are supposed to be. I didn't change the main model name for any of them, because the tutorial. They worked fine yesterday, but now some of them don't show up. Absolutely no heroes are showing up.. not sure if that is the problem. Please help!
