this was done for a very certain task...
i'm working with team mates who work in maya platform while most of the work is done by 3ds max and it plugins..and i work on both but better at 3ds max..
If you ever tried to export an FBX file from maya to max you will suffer from two or three basic things,
1: all materials are phong with high specular
2: some maps were defined in maya in som way that max understands them as maps with map channel != 1,then the need a uvw mapping
3: some faces problems
fixing these in a very big scene could be very painful
