Summary
This stream covers importing MaterialX files into Solaris, how they can be modified and finally how to mix multiple surface shaders to produce gold flakes embedded in marble.
Reference images of gold flakes embedded in quartz and other rocks.
Example materials that ship with MaterialX and can be found in the Houdini install directory:
$HH/materialx/resources/Materials/Examples/StandardSurface/
Materials downloaded from Ambient CG contain .usd files which can be imported into Solaris using a reference LOP.
The blending of surface shaders is controlled by a spatial noise visualized below, this mask drives the mixing and blending between marble and gold.
