Problem with AA Weapon Skins in SH
 

I have previously made a BAR skin for MOHAA. It still works in AA, as with all the other mods i have in there. Except, all my other mods work with SH, except this weapon skin. any ideas why this would be happening?
The thing that gets me is that the Character model skins all still work fine, it's just this BAR one that doesn't.

disable the "compress textures" in your advanced controls section
