Vlado, any change on the blend material supporting scripted ones?
Or does the support have to be done on a per-material basis?
hi vlado, yes i’ve seen it.
but now i suddenly understand it, after reading again.
my mistake was that i didn’t use the max density value, to stop the photons to be stored into memory!
first tests are looking promising…
i think this should be a standard option in the render settings, not a hidden maxscript line.
I just can’t remember how to start this material manually! Searched the forum and didn’t fin that tutorial, I know it’s somewhere. It’s about blend material, and making different colors of refraction based on the angle - falloff procedural. Can anyone send a link please!
Yes!!! That’s the one. Thanks!
Hello, any news about this shader ?
Best regards…
I was kind of wondering about this too!
We do have dispersion planned for the next major version of V-Ray.
Best regards,

which, of course, raises the question: when? 
Good to know…
