  1. How could you dynamically reassign the materialW so that it rotates based on the main direction the worm is pointing, so that it if rotates/collides/changes direction for any reason it still keeps moving “forward”? I assume it would involve a geometry wrangle in the vellum solver somehow extracting a directional vector (end points grouped during the setup, one subtracted from the other) and reattributing W? (I also assume that this could work on, for instance, a per-tentacle basis for a tentacled object, where a dynamically assigned W could cause the other tentacles to “reach” towards the predominant direction?)
