Dynamic Parenting In Blender | Dynamically Change An Object's Parent Using Child-Of Constraint

In this tutorial, we have discussed how to change the object parenting dynamically in the middle of an animation in Blender. We can do this by using multiple Child-Of constraints. We have taken a suitable example and discussed the use of this constraint along with its challenges. Please watch the video for the complete tutorial. If you have any question on this tutorial, please leave your comment below.

𝐓𝐫𝐢𝐯𝐢𝐚: The demo at the beginning of this video was rendered in Eevee with HDRI lighting and we forgot to take care of the shadow part, so the cart's shadow is looking awfully bad in the demo. We noticed this only after uploading the tutorial 🙁 Although it is not related to this tutorial, we decided to create our next tutorial on HDRI Shadow in Eevee, this week itself. So stay tuned 👍

[@caryfitz]

Very nice video, thanks! I found myself recreating the dopesheet by hand based on your description. It would have been great if the video showed its evolution.

[@WolfofBelgium]

Really helpful, thanks !

[@5MinutesBlender]

Glad it helped!

[@dikeythedocta471]

I think I found the answer to my problem. Thank you good man

[@5MinutesBlender]

That sound great 👍 Cheers!

Interesting Tip And A Nice Usage Of Child Of Constraint

[@ahmadzuhri6190]

Thanks, but isn't it better to apply visual transform when releasing the ball? This works too I guess

[@5MinutesBlender]

We can do that if you render the scene in two parts. As soon as you apply the visual transformation, it will remove the first part of the animation. So if you render the first part, then apply the visual transformation and render the second part - then it can work. But you cannot edit the first part later.

[@nikolas4749]

Thanks for this great video
I have two questions
I wonder if the cart use a follow path constraint to move along the tracks ?
and if I want to have multiple carts do I have to repeat all the step or is there a way to duplicate the animation

[@5MinutesBlender]

Follow path constraint is perfectly ok, the cart can move along a path and the ball will stay with the cart as expected. For multiple carts, you can simply duplicate them - just take care to assign the right path and the right parent for the objects (since duplicating them may actually create duplicate parent/child etc).

[@nikolas4749]

@@5MinutesBlender Thank you
for the ball animation do i have to do it manually with child of constraint or is there a way to duplicate the animation ?

[@eserakar7743]

What if the ball suppose to be at the edge of the cart, not the center of it. Then Snap to selected doesn't work for me and it's really hard to relocate the objects where it supposed to be at the end of where cart goes. Let's say i have 10 balls inside that cart and not single of them placed in center...

[@5MinutesBlender]

What I'd do in this case is, I will first create 10 empties and place them as appropriate in one cart. They can be anywhere inside or outside the cart as per your requirement, need not be at the center. Now I will parent the cart for these empties (with keep transformation). Now wherever the cart goes, these empties will go there and will maintain their respective positions as well. Now come to the ball. I will use a Child Of constraint to make this ball a child of the EMPTY (not the cart), so it will take the place of the empty within the cart. By using two such sets of empties for two carts, and two child-of constraints, I can move the ball from one cart to another, and it need not be at the center. For 10 balls, we need 10 empties in cart-1 and 10 empties in cart-2.

Amazing❤️ Sir and Thank you ....but slowly slowly blender lessons are getting complicated🥺

[@5MinutesBlender]

Thank you for the appreciation 💝 I am sure things will become easy when you practice more and create your own compositions with various objects. All the best!

[@19CarlosGomez64]

​@@5MinutesBlender I'm sure one day Blender will surprise us with a more direct method of changing object's parent. Something like simply key-framing the target object within the "Child Of" constraint. As always, this tutorial is an excellent example of pedagogy.

[@5MinutesBlender]

@@19CarlosGomez64 Yeah, let's hope so. And thank you so much for the appreciation, it really means a lot 💝💝

[@nileshparmar08]

Sir Please make video on "depth of field" in blender it will help me and everyone.
can we blur background in blender from our subject??

[@5MinutesBlender]

Yes, we can blur. We'll come up with a tutorial on depth of field. Thanks for this suggestion 👍

[@nileshparmar08]

Where are you from
I respect your Hardwork

[@nileshparmar08]

I wish you have millions of subscribers 😊😊

[@Porkupine69]

I think I figured this out
But could never make it smooth enough

[@5MinutesBlender]

Ok, which part was not smooth in your case? The movement of the object during the switch-over? If you give me some more details, I can try to suggest some improvements. Thanks!

[@BennXdesign]

the tutorial is good, but the method (the only one possible at the time without addons!!!!!) is horribly complicated and difficult to do. furthermore, if the client want to change the animation of the carts just a little bit, or let say, the position of the ball inside the carts, you would have to redo EVERYTHING from scratch!! now, let's just imagine that you have a cascade of several carts like that.... what a hellscape! nightmare fuel.
if you are a mechanical animator, this is by far, the worst weakness of blender.
we really need a way of parenting on the fly, with baking of the child coordinates in world space (visual keyframes) in background. Doesn't even seem so difficult to implement code wise... IDK why the blender team don't do it.

[@5MinutesBlender]

Agree this is complicated and may not be suitable in a complex scenario. Hope we get more flexible methods in future 👍
