Ok, so he got the bar fixed. Somewhat. Textures still load wrong in both programs but at least I can fix that. Now it's the ceiling that I just noticed does the same thing with exploding polys. I feel bad pointing it all out... but shouldn't these things have been noticed in the QA process...? And again, it does it on both programs. I completely understand when a vendor doesn't support certain programs, but that usually is just materials' wise, and like I said, that's something I can change and fix to my liking, but when the models themselves aren't right...? And I also understand that in the product page he put that P8 is recommended; but right before it it says that it works and P6 and above. 

A quick trip through PoseRay fixed the exploding poly in the ceiling but got completly rid of a particular face where the poly came from. What now?
