CD shader?

[Dschaga]

Hi, i found out that there is no map in max which can simulate the spectral colors of a CD.

any suggestion how to simulate such a surface?

there is a free map shader plugin in the web. Think it's called spectral or so.

The real effect is a combination of very tiny bump and a spectral light breaking that is currently not possible with Vray. Anyhow would take ages to render because of AA and split IOR.

How much time ya got to render?

could you give more detail on the free spectral shader? I could only find one that came with Cebas products....

digimation came up with something new called difrracter.

Maybe that will help.
but i dont know if it will work with vray.

so, is there any free solution or workaround?
You know, i don't want to buy for every problem of max a new plugin.

RErender, that image looks impressive, but this is an overkill for the job i have to do.

well, looks like this chap got some realistic looking spectrum working through a refractive material and a gradient fill (check bottom of the page)- perhaps you can do this by throwing a rainbow gradient map into a reflection chanel- uvw map of course to cylindrical. It's just an idea but it may work with some tweaking. I think this is just about the only other way to avoid long render times.

If you want to buy one- this may work:

And this is alot of work but it's just plain cool:

Ill let you know if I come across anything else. I can't seem to find the free plugin for it.
