Wrapping Illusion

Okay, now Ive exported the cliffs from an arena in Halo 2, then converted it and its skins for wc3. All works well in max as well as the wc3 viewer...however when the model is later imported into the game, the skin is stretched accross some areas, while wrapped properly in others. Why, and how do I fix this?

I can attach screenshots if need be.

Tim u no who i am dont u its dan lol well maybe something is up with w.e or maybe the model hmmm ....... lol thats wat i think

Does the model have bones ? If so when you export from max the bones get kind of distorted and make the skin stretched across areas. The only way to fix this is no bones but then it wouldnt work properly. If there is a way to fix this I do not know.

There are no bones. This model is cliff walls and a ground terrain. No animations.
