Hi Indranil,

Seems others have been down this path. Check out the following links which should help:

Opal Material

I found this video on vimeo. It purports to have been made using cycles, but there is no tutorial or node group for it. Was just wondering if perhaps the person who made it is a member here and could provide any insight? I have been trying to create such a material, but haven’t had a lot of luck with it.

OPAL material NODES here + tutorial on YOUTUBE

Thanks! Its nice for me to see that my work is making its way in the Blender community.

Cheers and stay safe!
