Hello,

I want to fracture my object consecutively, say, I have 2 sets of constraints, first break “concrete_fracture_1” then break “concrete_fracture_2”. My purpose is when pieces from first breakage fall onto the ground they break further. RBD Material Fracture node gives these 2 sets of constraint groups but I don't know how to effectively delete them to achieve my purpose. I tried Delete node on constraints only, but it seemed RBD Bullet Solver didn't like animated bounding box.
