Patreon Tutorial #34 - Part #20 - Using OSL - Marble (Patreon)

In this tutorial I will be going over a Closure based OSL node. These nodes are entire materials unto themselves unlike many of the other OSL shaders which are inputs for a material like the rsMaterial which generate patterns. This material is great for generating marble materials with several parameters to adjust from the coating, roughness, the marble vein shapes and colors. This node in combination with some Maxon Noise's for inputs can give great results quickly and easily. I will be going over all the parameters and how we can use them to make a black marble material.
