Softimage 3D 3.8 Extreme boxed set – eBay
Complete boxed set of Softimage|3D 3.8 SP2 Extreme – includes installation discs for IRIX and Windows, manuals, pamphlets, and a working license file.
Soft|3D runs great on vintage SGI hardware because it is highly streamlined and memory-efficient. Even an Indy will run it perfectly. Requires IRIX 6.2. You can check my photo gallery for a screenshot and a description of the software.
This is the ultimate classic 3D animation package – along with PowerAnimator and Renderman, it was part of the trifecta of high-end 3D apps used by the major visual effects studios. The huge box looks awesome on a shelf, and the software is a joy to use.
