Hi.
This is my try to achieve dispersion efect in octane.
One material has 5 different wavelengths and 5 different IOR.
Because the color efect direct from octane is low, I have added the color intensity in post production. Each submaterial must have reflection and difusion power more as 1, due this is this methode verry unefficient.
Regards...

Nice, I'm working on a shader like this, and already wrote about it in my second part of PDF manual I'm preparing.

Would it be possible to see the material setup? I'd be quite interested in replicating this sort of effect.
