when you mirror an object or adjust and axis, apply a Reset Xform (utilities panel) Then if you see the polys inversed, apply a Normal modifier, flip and then collapse the stack. This should then export nicely.
Max does alot of things internally so as not to bog down the artist with some things. When exporting, its a different matter, so some preparation needs to be done. eg Reset Xform, collapsing some stacks, etc.
- havent looked at your model yet.
