Summary

Building a shader from scratch in Solaris with MaterialX. The color values are retrieved from the geometry "Cd" attribute and the displacement pattern is generated using MaterialX math nodes to remap the surface position to a waffle grid-like bumpy pattern.

Below is the MaterialX shading network.
