Psyop: Open Sourced Arnold Shader “JF Nested Dielectric”
Plugins linking to this thread: (hide)
JF Nested Dielectric Psyop and Psyop's Head of Lighting (NY) Jonah Friedman proudly present JF Nested Dielectric,
an open sourced nested dielectric shader for Solid Angle's Arnold Renderer (Psyop
blog entry).
In large part, this initiative is an implementation of the 2002 paper »Simple Nested Dielectrics in Ray-traced Images«
nested_dielectrics.pdf by Charles M. Schmidt and Brian Budge and is meant to solve one problem: efficient,
physically-plausible rendering of nested dielectric surfaces in production. It's also
capable of spectral dispersion, direct refraction of light sources, production-feasible
ray traced blurry caustics. It has a few different optimization techniques built in
to improve render times, including Russian Roulette and energy tracking and clamping
throughout the ray tree.
Demo video: JF Nested Dielectric Demos. Illustrated documentation: jf_nested_dielectric_manual.pdf.
Testimonial by user AlexanderM in the si-community thread: Amazing shader. Arnold is now able to render ANYTHING.

Glossy Speculars still take lots of samples in arnold though 
Re: Psyop: Open Sourced Arnold Shader “JF Nested Dielectric”
Softimage 2014, Arnold 4.1 - works! (in Arnold dropdown menu got new DLL SHADERS sub menu, where i can find jf_dielectric shader)
but in Softimage 2013, Arnold 4.0 - doesn't work, maybe, somebody got success with it?
P.S. Installation instructions used:
https://support.solidangle.com/display/ ... om+shaders
[UPDATE] Damn, thing was in copying SPDL file, which was inside sources folder
NOW WORKS!:)
