I am trying to render diamonds in Rhino 7. I built the geometry of the stone in Rhino.
But when I apply the “gem” material and try to render, I’m not getting any kind of light refraction
or the program picking up the facets of the stone. I’m rendering on a sold color, white background…
using the “Gem Studio” environment for the reflections and the lighting.
Note that if you move the camera, things will quickly get out of focus, since I enabled focal blur in Object Properties for the new (named) views.
To show the difference made by swapping the diamond and doing the boolean difference, here is the original setup, but with those changes (I apparently also made the gold a bit less matte, to make it pop a bit):
