mattak posted a topic in Animation & RiggingHi all, I've run a ground while building a set-up for creating centroid points from surface prims, animating/deforming the points, then applying the animation back to the prims via a matching prim_id or prim group_id. The prims in question are separated via facet and partition sops, and all their numbers do match/correspond to the animated/deforming point numbers. The lookdev would be sections of a surface dissolving/evolving via the incoming point motion. Something roughly in this direction: I'm just not sure how best to go about copying the motion back to the prims. After some heavy googling, I've been looking at forEach and copy_stamping as an approach but no luck so far. Have a look at the attached hip. Any help would be appreciated. prim_id_or_group_id__to_follow_point_id_motion.hip
