This is just a proof of concept of dispersion for cycles. It is not meant to replace bidirectional engines.
One frame took me about 40 minutes.
I love it, this is definitely my favourite glass shader for Blender so far!
so much love man this is amazing do you have a patreon ?
Thanks, I'm glad you like it. I don't have a patreon, but I'm planning it because some people have already asked me about it. Who knows, maybe in the future.
