I was working on a baby project in which a toy trains takes a block (typically a cube).

So I parented the block to the train and it moves perfectly from starting point to the stopping point.

At the stoping point I want this block to be un parented and start moving along a curve.

enter image description here

If I try to un parent it using Alt + P its jumps around as shown below:

Parenting can't be disabled during timeline. If you want this, you must use Child Of constraint instead. It has influence value, that can be animated.

  • $\begingroup$ Thank you very much for your answer, so how can I set child to un parent on a certain frame and keep the location same ? $\endgroup$ Commented Oct 22, 2017 at 11:44
  • $\begingroup$ Use two Child Of constraints. One is referencing the moving object and the other is referencing the static one. Animate the influences to obtain the desired effect. $\endgroup$
