Abstract:
We present our solution to simulate light refraction in deformable characters’ eye corneas in Autodesk® Maya®’s viewport, with a result close to the final render, significantly reducing iterations for facial animation workflow. Our approach is tightly integrated with our GPU-based deformation engine to minimize the impact on playback. The refraction is generated automatically from the scene’s geometries, and a simplified shading definition is exported by the LookDev department using Pixar® Universal Scene Description. It has proven to give reliable results, allowing for its adoption in production for all current and upcoming shows.
