Houdini Tutorial: Procedurally Create Detroit Agate with a Karma Shader

Once you start to cut and polish these rocks all the individual color layers are revealed and create a color explosion. In this tutorial we’ll build a VEX based Karma shader to mimic this gemstone-like look porcedurally inside of Houdini.
