Abstract:
We introduce a new workflow for plant animation built for Avatar: The Way of Water. The workflow combines new solver features with a suite of procedural workflows to streamline the massive scope of setting the virtual world of Pandora in motion, while pushing the final quality beyond Wētā FX’s previous plant simulation capabilities. More physically principled plant simulations including codimensional simulations and coupling of multiple solvers, a production workflow for asset library motions, and procedural tools to help run and apply the high-fidelity solvers to scene plants are a few of the improvements introduced to bring Pandora to vivid life.
