i cant see that really well on phone, but you've added a character right ? if that's the case, its a bad idea you can replace existing characters in the texture name, but not use a longer/shorter name.
It would be nice if you could write a tutorial in the wiki for this. If you have some minutes.Reskinning WMOs.
Why am i saying all the time object and not m2 or doodad?Because you can use the exact! progress on any object of wow. You can even create your custom wmos with that!It always works the same way.
