SilverwingVFX focuses on modeling brilliant cut diamond shapes in Maxon Cinema 4D.

A little while ago, a tutorial from SilverwingfVFX (Raphael Rau) showed some methods for best rendering diamonds with Cinema 4D and Octane Render. That tutorial showed how to work with Nested Dielectrics, and Clipping Materials for a mix of transparent (Diamonds) and opaque (Metal) objects to make it easier to visualize jewelry.

Shaders and ray tricks are only part of the workflow if you want to create a realistic look for gemstones. The other component is modeling. Here, Rau shows some methods for modeling brilliant cut diamonds.

Rau often takes specific rendering techniques and does a deep dive showing off things like working with nested dielectrics, ray switch nodes, and working with cryptomatte.
