Hi!
What settings can I use to render the ring shown in the picture like this?
Thanks!
Rhino render currently does not have dispersion for transparent materials. Also in order to get correct refractions/reflections, for Rhino render you will need to make sure the stone doesn’t intersect with the ring.
that being said: maybe the model I created for Shrinkwrap helps: Rhino - ShrinkWrap
Check out the Rendering tutorials here There’s one of a ring I did a while ago, no caustics unfortunately through the gem but may help otherwise.
