    I am creating an animation where stuff is falling into a blender. I am using the built in Veroni fracturing to make the pieces fracture and spin around the bottom of the blender as they hit the blade, but I want to try a version where everything falls intro the blender (without breaking apart) and then turn on the blade and things break up. Is there a way to do this in C4D? I have been through every dynamic setting and cant seen to make this work. Any suggestions would be appreciated.

    What I would do is keyframe the dynamics tag on the voronoi object. Specifically, in the Collision tab, set Individual Elements to None and then keyframe it to ALL (or Top Level) before the blades start up. You’ll also probably need to keyframe the Trigger paramter in the Dynamics tab at the same time, changing it from immediately to “on collision.”

    Thanks, that should work a charm! Truly appreciate it.

    I’m working on a variation of this same problem, Adam. I need to delay the fracturing of several hundred objects. So, it doesn’t seem like keyframing the enabled switch is the best way to do it.

    It seems like the solution lies somewhere in the realm of xpresso, . Checking for collisions via a collision node and flipping a switch, but my knowledge of xpresso is limited at best.

    Any thoughts on how to delay the fracturing of several hundred objects, dependent on when each of them intersects with a second collider body?

    Here’s my original post asking for help with this, more details.
