I have multiple rigid bodies and I want some of them being glued together in initial state and behave as a single object. Is there a way to keep them glued together and break apart at a later stage of the simulation?

  • $\begingroup$ how should they "behave as a single object"? fall by gravity? roll down a slope? adding some more details will help to understand what you are trying to achieve... $\endgroup$

  • $\begingroup$ @m.ardito All the objects have the same physics parameters, and when 2 of them should be connected they should have same physics behavior as a single mesh. $\endgroup$

You can use Rigid Body Constraint and keyframe Enable checkbox or set it to be Breakable (they will disconnect after collision - use Threshold value to control how strong this collision should be).


Without Constraint:


With Constraint:
