[Tanakov]

So Im working on this thing now with corona, my job is to make

Effect that I have (Only White lights for the test)

My question is is there a way to add dispersion?

http://forum.corona-renderer.com/index.php/topic,1127.msg22739.html#msg22739 Is this the only way so far?

The only way I could think of, other than the one from the thread you mentioned, would be changing reflection colour of some random faces. But I'm not sure what it would look like.

I would add my humble aproach. XD.
Until Keymaster implement a way.

Yes, Tanakov mentioned it in the first post and I mentioned it in my post. :P

the only way to achieve that effect in a procedural kind of thing is to shift 3 shaders with a slightly different fresnel IO for each and set them with the 3 main color you want to see through your effect. Plays with a fallof you tweak and you will approach something good enough to fake. But NOT the right thing though. Was on air for a while before Vray got a decent disp effect available.

Your method isnt bad, but when we dont have "Render Selected" option it seems to that its not very efficient. (but works)

yeah as we said, not the ideal solution. But in a positive perspective, it is quite cheap in processing ;)
