按颜色分隔物体Isolate objects by color in Houdini

Learn how to isolate any kind of geometry using color, we will learn a few different technics on transferring color from one geometry to the next or utilizing the color attribute on the geometry to split it. We are going to cover a few methods, including wrangles and group expressions. The following tips will will benefit simulation sources and control over geometry that needs to be split in art directable ways.
