I am looking to color elements without having to renumber them individually. I have tried different approaches to no success. The place that has gotten me the closest is https://answers.arnoldrenderer.com/questions/4677/drive-aiswitch-index-via-objectid.html, but I still cannot find a way to break things down into elements. I know that there is multitexture and mutliid but that is too slow on a tree and uses too much memory. Any suggestions would be greatly appreciated.
