GMax download at Turbosquid (Free)

Get this script: gMAX2OBJ.ms

• Put the .ms script into your Gmax/scripts folder
• Click the 'Utilities' button on the main control panel (looks like a hammer)
• Click 'MAXScript' button in utilities rollout.
• Click 'Run Script', navigate to gMAX2OBJ.ms and run it.
• Click 'Open Listener' in the utilities rollout.
• Copy the text window, save it as a .obj file.

It's convoluted because GMAX was specifically built to NOT export anything...
Works though...

Friends don't let friends use booleans.
