ABSTRACT
LightCraft is a system at Industrial Light and Magic that semi-automatically determines the parameters of digital light rigs using on-set imagery. It's a quick, simple, reliable, artist-friendly system that solves for the size and location of lights and creates ready-to-use emission maps and environment maps, for lighting in a variety of rendering packages.
The LightCraft system was originally developed at Industrial Light and Magic for the film version of Warcraft, but has since been used on Star Wars: The Force Awakens, Jurassic World, and Teenage Mutant Ninja Turtles: Out of the Shadows.
