Dispersion fake

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...

They look great. The second image is my favourite.

Hi steveps3.
The first is direct from octane and the second is the same, but little bit fotoshoped.

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

it's a pity, maybe with a more tiny light source
thanks tomas for your tests

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