When in unity frame lifecycle are rigidbodies moved to depenetrate?

    We have a kinematic rigidbody w/ a 3D collider in the scene. Then we instantiate another one on top of it. At some point after instantiation one of the bodies will be moved so they no longer depenetrate. When in the unity event cycle does this occur?

    Thanks

    During the simulation step where everything is done physics related. When does the physics step happen? By default, immediately after all the FixedUpdate script callbacks. You can though, turn-off auto-simulation and manually simulate it yourself whenever you like so it'd happen then.

    In short, as part of the the simulation step (solver stage) alongside things like physics callbacks etc.
