I started making a game and decided that the game would look much better using custom model files instead of the supplied WE model files. So I imported the models and textures and everything works fine and looks good in the editor, but when I run the game the item/character/whatever becomes invisible. This is really weird since I'm using the correct paths and when I try to view the models inside the editor they appear and act fine but only when I run the game do they become invisible. I am using Mac OSX if that makes a difference.
