PowerAnimator
PowerAnimator and Animator, also referred to simply as "Alias", the precursor to what is now Maya and StudioTools, was a highly integrated industrial 3D modeling, animation, and visual effects suite. It had a long track record, starting with Terminator 2: Judgment Day in 1991 and ending in Star Wars: Episode I – The Phantom Menace in 1999. PowerAnimator ran natively on MIPS-based SGI IRIX and IBM AIX systems.
