Abstract:
Collisions are a key problem in generating complex crowds animation. The mudskippers in Walt Disney Animation Studios’ “Moana 2” presented a particularly challenging scenario where throngs of floppy amphibious fish pack tightly together to form a towering pile. Our solution introduces an additional simulation step to deform the skinned character meshes using Houdini’s Vellum solver to resolve body-to-body contact. This departure from our standard deferred mesh generation workflow enabled an effective solution to this problem, and opens new avenues for achieving character deformations beyond the capabilities of character rigging.
