Well I had this problem one time when I was making a map, something in the Endor world file made the texture black. Well i am now making a side mod for my map and it says ScriptMunge.exe has stopped working. I have tried to do just a few things at a time but I did go out on a few limbs with this batch. I don't know what would cause that though. If anyone could atleast narrow the scope of the search down I'd appreciate it. (Skins, models, etc.?)

im guessing that means that something in your lua is messed up.
