Point Deform lets us transfer animation to any mesh (within reason) with just a buncha points. Lets create this contrived example, using this static mesh: And this animated “point cloud”: Wiring them up: For the second input, we use a TimeShift to hold the first frame of the point cloud animation, which gives us the “rest lattice” that matches the static mesh’s topology (ideally). All this essentially animates the mesh:

We can modify constraints and geos while a simulation runs by plugging in SOP Solvers inside a DOP. The wirings go like this: [Above] The blue SOP Solver messes with the incoming RBD Packed Object (after the Bullet Solver is done with it), and the red SOP Solver messes with the constraint network. The various solvers plugged into the Multi Solver (green) are evaluated left-to-right. In this case, the Bullet Solver does its thing to the packed object, moves shit around, then passes it to the blue SOP Solver.
