Upon exporting a .dae of a building, I noticed that it exported with double the amount of faces. I'm using maya 2013. I checked the mesh before exporting - cleaned it up, made it sure it had clean geo, and all the normals were face the right way. I deleted history and then exported. Opened the .dae in separate maya window, and it had twice the amount of faces. If you looked at it, it didn't appear so, but when you delete a face, you see that there is another face in the exact some spot. Almost as if it was duplicated on top of itself. Has anyone run into this problem? thanks
