Hi,

I recently doing some test rendering volumetric caustics with MentalRay, and after that, I wanted to see if it was possible to recreate a prism of light.
Unfortunately, there is no option of dispersion in the Arch & Design Materials.

Master Zap explains a method with a script. But it multiplies by 3 the rendering time.

There is a plugin / mentalray shader that allows for that. Prism Photon 1.0.0 by Ralf Habel
It is here:
maxplugins.de/mentalray.php?range=Photon&sort=Author#top

After some test you can see the result.
