why rbd packed object doesnt work well with cloth collisions? i have a case where i need to collide a voronoi fracture with cloth, but it just doesnt work, very strange results.

ohhh i found the answer, the problem was something that houdini itself warns you about, you cant merge diferent solvers with packed primitives, it just goes wrong, but i bet that everybody wants the best of two worlds, fast simulations from packed primitives with diferent solvers working fine together, so… i think that sesi should work on that.

and I find out if we use RBD pack bullet solver, just unpack after first sim then it could collide with cloth objects at second sim.
