Carnival Light Animation for Toy Story 4
The carnival scenes in Toy Story 4 featured over 14,000 animated light bulbs on rides and booths; animating this volume of lights with traditional lighting software like Katana was practically impossible. So, I developed procedural rigs in Houdini. Multiple animation variants were created for each ride and booth, providing options for scene lighting. In total, I created 127 unique procedural animation cycles for 12 rides, 7 booths, and the Toy Story logo used in the trailer.
