I made the Dinosaur-Rigs for a Documentary for ARTE Deutschland. My Job was also to setup the Crowd animation-Workflow. We had to animate dozens of Dinosaurs in a very short Timeframe and we where only two Animators. My Idea was to use the Animation-Layer system of CINEMA 4D which allowed us to mix different animations and use the same animations on several Dinos. That way we where able to quickly animate so many Animals.
