diffraction of light

[Francky]

I was just thinking that it might be cool to have this option.

I know that vray can't do this "normally". But there was a trick in 3dsmax, where we'd add 3 instances of a refraction shader, layered together. One Blue, One Green and One Red. All with a small variation in their IOR value. The resut was a normal refraction with light diffraction. I guess the mathematics of light diffraction are much more complex than this, but it was a cool cheat.

I was wondering, would the current level of access you guys have to the core of vray allow you to have 3 diverging values of IOR ? (for each color)

It could be cool to simply have a "diffraction" input box next to the IOR input. :D

Then again, if no such control exist, never mind :D

yes,
this will be available when we have the vray shaderes added to the c4d shaders. planned for 1.2

Vray Shaders ? Oh this could be really cool.

A thing vray was always missing on Max was shaders, especially when compared to final render. This could prove to be awesome ;)

Thanks

so far you can do that by rendering out 3 pics with slightly different IORs
and put them together in PS.

you normally merge 3 vray shaders with the vray blendmaterial to achive this effect. thats why i meant with vray shader you will be abale to do that.
