that sounds like a texture error, try to figure out which model is causing it by removing 1 at a time, then when you've found it, import its texture in a different format, and before that, make sure you have all the textures you need named correctly.
The thing is all 3 objects only use 2 textures and they r all using the same 2 textures. I checked and everything is named correctly. the only thing i can think of is somehow the coordinates on 1 of the objects is somehow messing the texture up or something? 2 of the objects r exactly the same and 1 of them is different. the 2 that r the same r fine, but the 1 tht is different is not showing up.
edit:
it cld also b the animation file i added tht has all of their bones. This file has properties: FrameCount and Unknown1-3. I am not sure wat to put for these
