AutoDesk, the company that now owns Gmax, a free 3D modelling utility used by many modders in the C&C community, had the following bad news for us, informing us of their
discontinuation of Gmax:
As of October 6, 2005, Autodesk will no longer offer Gmax© software as a stand-alone product. If you are interested in other 3D animation, modeling, and rendering applications from Autodesk please check out Autodesk© 3ds Max© software. You can download a free 30-day trial, view product demonstrations, read customer success stories, and get more information about this powerful, versatile product.
PlanetCNC has a nice post with more details on this.
