Didn't someone make a utility that would take a GMAX file and change it into a .mod, by way of going through a couple of other formats and programs. It sounded at the time like it was more trouble than it was worth, but for those without access to any 3d modelling program it seems like the way. Isn't milkshape like 20 bucks or something? I'd say if you really have an interest give that a try.
