One of the most popular modeling programs in game design, it is a very powerful toolbox. Discreet, a division of Autodesk, makes this program along with several others for creative professionals, in not only the entertainment software industry, but for motion pictures, visualization, architecture, and many other professions. 3ds Max comes with several options for modeling solids, including polygonal modeling, NURBS modeling, and patch modeling.
GMax, a free version of this program specifically designed for modding games has been discontinued.
