vikola Posted yesterday at 06:29 AM Share Posted yesterday at 06:29 AM (edited) Hi houdini expert! I'm in Houdini 20.5. I’ve got a pre-fractured sphere made with rbdmaterialfracture → rbdpack. Using copytopoints, I duplicate it on some points that i had previously cached. The spheres are emitted over time with emitRBD, so they don’t all exist from frame 1. What I want is for each sphere to explode the moment it’s emitted, with the force starting from that sphere’s center and affecting the individual fragments, not the sphere as a single packed piece. After copytopoints I’ve got an rbdunpack connected to an rbdbulletsolver. With only the gravity each sphere, when enter in the simulation, start falling on the ground and the breaks. How can I make each emitted RBD sphere explode outward from its own center, with the force applied to its fractured pieces instead of the packed object as a whole? The explosion should start in the first frame each ball enter in the simulation. Thank you!!
