Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

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:
user added image

But I want that:
user added image

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.
