I have to port my work over from Maya 2012 to Max 2010 before handing it in to be checked over by the boss, and I'm having a ton of troubles with normals. Max seems to be randomly hardening edges, flipping vertex normals, things like that. I need to get this fixed so I can move on to the next project.

Right now my process is model it all, clean up the scene, name everything by the guidelines I have to follow, clean up the scene (freeze trandsforms, delete history, clean outliner, etc.), then export as FBX and import to Max. Should I be using a different export/import format or something? Anyone had these problems before?
