If you mean, where is the plugin for it, you go to the downloads page...
MAX2GS (shareware - free trial version)
MAX2GS exports a MAX scene to Gamestudio with a click (or perhaps two). The MAX plugin exports level geometry with baked textures, sprites, terrains, lights and cameras, and places models and WMBs. It creates the scene file (.wmp), the material library (.wad) and the script file (.wdl) in only one step.
