One of the great things about the Houdini community is that we’re always confronted with clever questions and with clever answers too. “How do I color strands using an image’s color palette?” was the comment on Vimeo that led to this setup. Yet when talking about coloring polylines we also need to discuss rendering them.

In this video we’ll go over setting up a basic point advection through a vector volume using purely Houdini standard tools. Also We’ll show you a way to hack the standard Mantra Material to behave like a hair material.
