Lithunwrap is a FREE legal utility that assists in saving gmax 3D content  to more portable and usable formats.  Import formats include the 'Quake' .MD3 format saved from gmax 1.2. Mesh content  is easily exported to .OBJ, .3DS, .LWO, .X, .DXF, .COB, .MS3D, or .NOD.  formats. Performance is good with conversion taking a minute or two at most, depending on mesh density and hardware specifications.  The example above, comprising 1,037,570 faces was converted in 90 seconds or thereabouts.  This is a little slower than 3D Exploration 1.5 (which can still be located online) but is a great deal faster than script based methods.  A photo-tutorial detailing the process is available .
