Thanks Eiffie for sharing the code.

Yes, many thanks Eiffie!  That is such a brilliant shader to experiment with and build on.

Awesome stuff, Eiffie

I made a few small corrections to the code in my last post since I had gloss working backwards. Also added the fresnel equations for refraction/reflection which sped up the convergence. I still need to fix the fog (no fog in reflections yet).
I put the code in the last post just to be confusing

Even fast enough now for some short 720p videos.

Finally corrected a problem with the script that applied the diffuse color even to specular light. The updated script is on the previous page - named eiffieGI2.zip
