Diffraction shader help
 

Hello, I try to create the texture of a compact disk with the diffraction shader of Maya. It's a specialised shader that can be used to create realistic diffraction effects like the rainbow reflections created by a CD. But when I apply this shader on my disk all the "rainbow" go in the same direction.

I have this:

But I want that:

I don't know how to proceed! If somebody knows this plugin and could explain to me...

If you want to test this plugin I put it here (for Maya 4.5).
For Maya 5 you can find the diffraction shader in the bonus tools 5
on the web sit of alias

Thanks a lot

Maybe some of this will help you. Unfortunately, no screenshots are available anymore as they were purged a long time ago but any zip files including a short animation I did using the diffraction shaderare still there...

Thanks a lot Nitro it's ok now!
But I have another question!
When I applied the diffraction shader on my cd all the objects in my scene are not reflected on my cd. I activated the raytracing but it doesn't work!! Only the lights and the environnement are reflected!
What's the problem?

Not sure. If there's a read me with the diffraction shader, it might give some tips as far as reflections are concerned.
