MPM Post-Fracture fractures the renderable geometry represented in an MPM simulation using the final frame of the simulation. It attempts to fracture the geometry exactly where things are breaking or bending so that the renderable geometry can accurately capture the dynamics of the MPM simulation while preserving all of its original attributes.
MPM Deform Pieces will throw an error and complain about the geometry not being fractured.
