I'm trying to get a more interesting silhouette out of a viscous sim across a flat surface. Sim is nice and goopy, but very even around the edges, almost circular. I'm attempting to use a camera mapped texture to modify the friction of the static collision geometry, but I can't get any attributes out of my Collision Source volume and into my Static Object in my AutoDopNetwork. I've tried getting Cd data onto my Collision Source, and wrangling Cd to Density, but neither is letting me pull an attribute into the Friction parameter. Is there another way to do this that I'm missing?
