I got really bored at history class today and I started to design a sword which I could perhaps model into wow, but I am not sure if it is still possible cause last time I tried it kept complaining about skin file being corrupted --_--
So is modeling a weapon with 3ds max possible and then adding it to wow possible? And if yes what format should I save the file to make it able to be edited into .M2 and .Skin?
