Mark's VRML97/X3D Export Plug-in for 3d studio max replaces the original discreet VRML plug-in. It is vastly improved, with new features and key bug fixes. Finally your ISO VRML97 output will look like your max model with no hand tweaking. The objects will even be the same size in VRML space as they are in 3ds max. Best of all this plug-in does not crash 3ds max. It even has useful context sensitive help for all controls. Use this exporter to share your work in all its 3-dimensional glory with colleagues who do not have access to 3d studio max. Once exported as VRML97, they can view your work using one of the excellent free VRML97 players that are available on the web.
