material problem

hi there, exporting from max to ogre using ofusion all the model shows a yellow material over the textures, and (that's really strange) at certain camera angle all model disappear. This happens just with a model of a room that i made, not with primitive or similar.. i'll soon post a video if someone already knows the solution i'll appreciate.

Could you provide more details, is this in your application?
