You need something that will convert to .3ds format.. and then you need to get O2/Bulldozer.
Never used GMAX.. .so Im not sure if it outputs .3ds
once you have .3ds file you can get this program...
http://www.anim8or.com/main/index.htmlwhen it opens.. go to Objects>Import and then import your .3ds file...
find the debug option.... can't remember which menu it is off of... but it's one on the top of the window there....
make sure the "dummy 3ds KData" is checked off.. then export>object
now you can import to O2
hope this helps some..
