Opal - revisited

I tried to create an Opal like effect a while back - with mixed results. I had an idea this morning on how to make it more realistic using volumetric materials. Basically I use the wave texture plus colour ramp to create thin inclusion layers throughout the volume. I then mix this with a noise texture to give small island inclusions. I then use the result to key the density of a volume scatter node. By setting the anisotropy of the volume scatter negative - I can make the inclusions retro-r…
