Practical and Controllable Subsurface Scattering for Production-Path Tracing

Subsurface scattering rendered using brute-force volumetric path tracing looks more natural and is also more robust compared to popular diffusion-based approximations. This talk proposes a reparameterization formula that allows artists to use the production-proven intuitive controls, and it introduces a sampling scheme to make the formula practical for production rendering.
