tl;dr: An oral history with ILM veterans on the pioneering CG tools built for Terminator 2's T-1000, including "Body Sock" (for stitching b-spline patches across animated joints), "Make Sticky" (an early UV-mapping technique for texture adherence), and a custom "poly alloy" RenderMan shader that faked ray-traced reflections using placed reflection planes. The team of ~12-15 people used Alias and SGI hardware, rotoscoped Robert Patrick from dual VistaVision cameras to build the digital character, and largely invented modern VFX workflows on the fly—including overnight rendering, match-move edge detection, and procedural displacement for shots like the head-through-bars.
HN Discussion:
  • Appreciation for practical effects like custom squibs alongside the CG work
  • ~Article overlooks that Softimage was also used in production
  • Awe at how much VFX foundation was invented from scratch for T2
  • Recommendations for related documentaries and behind-the-scenes context
  • T2's cultural significance and technical achievement remains unmatched today
