But it doesn't work in game or in the editor, well it patially does but not 100%. The problem is many of the skins are "invisable" with the exception of the Necromancer and Medivh skins, is there a way so I can fix this and make the Necromancer skin invisable (I don't like the idea of a Nightmare wearing a necromancer's helm). Oh the skins DO show up in the spell casting animation for only a short while.
I have almost no idea what you are talking about because I have 0% experiance in model editing, but I guess, what your talking about sounds like MDL editing, I'll try it, but I have no idea what i'll be doing.
