Animation of RBD Packed Object informed by the simulation geometry it's affecting in Effects Posted November 19, 2019 Hey Pavel, Thanks so much for taking the time. This info will really help me a lot. I've never encountered the Empty Data and Enable Solver nodes before, but I think I understand. It seems like the Enable Solver tells Geometry Wrangles which objects to apply to by entering the names set by the Empty Data node.. And I'm not sure how the names will come into play, but hope to remember that tip when I get into constraints. Thanks a ton!!
