JF Nested Dielectric is released as a Psyop open source initiative! It’s a shader for Solid Angle’s Arnold Renderer. It has one purpose – efficient, physically-plausible rendering of nested dielectric surfaces in production. Licensing info, source, and DCC helper files are available in the Git Repo linked below.
In large part, this is an implementation of the 2002 paper: Simple Nested Dielectrics in Ray-traced Images by Charles M. Schmidt and Brian Budge
- Full documentation (PDF with lots of images)
- Git repo for source code, builds, and licensing info

Update: I have released a video of a unreleased photon mapper for JF Nested Dielectric, JF Photon. This was unfortunately never finished into a product suitable for artists, but code is available on Github.
