- 🚀 Our 'Blender Animation Course Kickstarter' was super duper successful with over 440 students! 🎉 Next time we open spots is mid 2022. If you'd like to stay in the loop with course updates and free animation tips, join our newsletter! :) 🔵 www.toanimate.ca/
Description: Constraints can be very complicated and not so easy to grasp, especially if you're new to animation. I've already made a 3 part series talking about constraints in Autodesk Maya, and well.. it's about time I do the same for Blender! In this video we take a look at how I used the "CHILD OF" constraint to create a cool little animation in Blender!

the way you positioned the gun at the beginning so that it just slides into his hand so conveniently :D i wish it was always that simple
😎😎
Thanks so much! I was so frustrated as a beginner looking for ways to attach a sword to a hand, it seemed so simple, yet I couldn't find any good tutorials on it. Thanks for saving my night!
I've definitely been there. Happy to help!
Outstanding, clear information. Many thanks!
Watching now. Love the professionalism in the video. I'm currently on the hunt for a tutorial on keeping both hands (primary and secondary grip) on a gun, but having a hard time finding anything
Blender needs to work on this feature, something as old as SFM can do this with little to no problem whatsoever.
You do not know how much did you help me. You are absolutely legend🤩🤩
you are amazing !!! thanks!!!!
thank you for the this i always struggle with constraints alot
😭 Don't we all... lol
you are saving lives with this video
i have been looking for this Man thanks a lot bro
Nice!
I love how a lot of tutorials and course are coming for blender animation. I remember the time when blender animation tutorials were so hard to find
Same 😂.. decided to do something about it.
@@BrianKouhi I'm glad!
Nice content! But you don't have to apply the visual transformation... you can skip that anoying process by clicking on the X right at the end of influence slider. Hover the mouse over the X and see the tooltip. ;)
Noted! That would definitely save some time, I'll test it out.
Holy shit.. I didn't know about the "child of".. I always tried to use "copy transform" which is just completely random.. Thank you!!!
Haha It's always the little things that are helpful and easy to miss
You are a life saver
Glad it helped!
Thank you for this, I need it desperately.
Like the
Now, Gunzo is Gonzo
😂😂
Usefull, thanks!
😁😁
Have you tried the addon "dinamic parenting"? I thinks Is free and saves you alot of head pain
👀 I'll have to look into it, I've never used it. Thanks Christian.
before this i used to render the part where the object was parented and then changed it and rendered the part where the object is not parented after :D I realize this works a tad better
Hello, nice!
How do I pick and drop the object multiple times? Do I need to create other 'child of' constraints? Or can you use the same one?
I want to constrain a weapon to the hand. I followed your steps except I don't want to let the weapon go. When I move the arm the weapon floats away from the hand. Is there something different about Blender 4.0 as apposed to the version you are using? I am constraining by using the ctrls of the hand and the ctrl of the weapon. Do I need to use the bones for the character instead?
ohh nice but ,how to bake that constrains as keyframes to export to unreal engine ,i am begginer for blender ,can you tell me bro
I've never worked with Unreal, but one thing you can do to bake is to select your constrained object or rig, go to "Object or "Pose" depending on what you're constraining, you can find this usually on the top of your viewports. In this case with Gunzo, it would be Object -> Animation -> Bake Action . In the Bake Action menu check 'visual keying', and once the bake is done, delete the constraint and your object should pop into the right place & keyed in the timeline. Hope this helps.
@@BrianKouhi Wow Very Thanks You brother 💜 Love all your Tutorial ❣️
@@RunorDieyt Glad you're enjoying the content!
Simple fast helpful ,just how
hey there, this is useful for one weapon or prop? I mean , I am searching a universal pipeline to export my animations to unity, I do not need the same weapon, I need certains animations , such as Holding Xweapon (where X is whatever weapon) , I need fist-trigger weapon, (some kind of fist motion to shoot) ... I need different weapon but same principle... I do not use any constraint because In unity you can do not export blender's contraints.
This is awesome stuff!! I love Gunzo's sense of humor =p.
I just had one question. What if you wanted to constrain one character's hand to another character's hand. I tried doing that a couple of times but it always ends up snapping the entire rig's attributes back to default. Does that ever happen to you or is it just me and I'm doing something wrong? 😅
😅 Gunzo gets out of hand with Dad jokes sometimes..
I think that's a great topic for a video! May's wrapping up rigging, so I can use Max and May as an example 😁
Super helpful, thank you. I subscribed! Just curios, how did you learn to use this constraint properly? I can't imagine trying to figure this out on my own.
By being thrown into a Netflix production and having to "figure it out" for almost 2 years 😂
lost for 2 days, you saved me!
Thanks a lot for the tuto.
But what if max wants to pick it up with his right hand next ? Can the gun have a list of multiple parents during the animation like in 3dsmax ? Can i repeat the same process ?
I'll be making a tutorial on just that! It's hard to make 1 video on constraint since there's so many different scenarios where it'll be used different 🥲
@@BrianKouhi thanks a lot and good luck
I tried to do this before and got stuck in the last part (0 the influence). I won't talk about my workaround 😂. You can't imagine how this video is useful for me, thanks!
Haha I can only imagine! happy to help 😁
nice tutorial however when i animate the hand then it only moves slightly and doesnt move to the position i wanted it to be its weird
🧡🧡💖💖
6:35
i used ctrl shift C instead of the modifiers tab and now i can’t get rid of the child of modifier…. help
More and more
I followed the steps all the way to object apply, visual transform, but the object keeps popping back away from its position. anyone knows whats happening?
I have the same problem :(
So, has anyone tried the actual course yet? How is it?
The true pain is when you have 3+ child of constraints and then one of them breaks c:
hey how come when i try to child of constraint a gun to characters hand when i click set inverse it locks into position, but when i scroll on the timeline the gun moves to a random spot and isn't locked onto the hand. what am i doing wrong ?
Did you set keys on location, rotation, scale before constraining?
@@BrianKouhi nope, so once u set inverse and it goes to the right position, that’s when u set the positions or do u set the post ion before adding constraint ?
@@xomeep Make sure to set the position before setting the constrain, so Blender knows the actual position of your object.
Let me know if this fixes your issue.
@@BrianKouhi will do thank u !!
@@BrianKouhi it worked ! i appreciate u, ive been trying this for 3 days
Uh, how do you do this, but backwards?
this tutorial allow me to maintain the same object on different targets.thank you young man
😅
i love you
I love you too random citizen!
GONEZO IS GONE-Z-O 😃😃😃
When I reduce the effect to zero, I want the gun to stay where it fell, and that doesn't seem possible. this is so annoying i want to punch my computer. and after this video i will try again. this must be easier to find how we can solve the problem before watching this video it's so stupid in terms of blender creators.
Yeah it's not the smartest way to do constraints. There's also the dynamic constraint addon you could consider. I made a video on It recently. Makes constraining very easy.
@@BrianKouhi thank you i will check it out
Can the Blender foundation fix their child of constraints
The child of constraints are genuinely dogshit and makes me want to move to 3ds max
Constraints in Blender is a breeze compared to Maya... there was ALWAYS something going wrong with Maya constraints.
Ain't that the truth 😂
> "We have to tell the child who its parent is."
Is that joke adopted?
😁😁
walking with a hat on the head.then pick this hand with the hand and walk with it in this hand.after put this hand on the head again and walk with it on the head.finaly remove this hat on the head and kkep it in the hand.
imo this is poorly designed. this probably gives the maximum flexibility and addresses all possible edge cases. but they really need to make a version of the tool that will do what users want 99% of the time - STICK HERE, RELEASE THERE (!) - and just automatically do all those other steps. ugh... was soooo hoping this would be faster and easier than maya always having to have a separate constraint to bind to on space-switching hand-offs but noooooooo.... just as complex and arguably harder to understand and more convoluted.
This is totally wrong way. U should do it with copy location and copy rotation. No need to parent reparent.
But wouldn't you run into the exact same 'issue' with copy location and rotation when you want to unconstraint the gun from the hand for a section of the animation?
How blender is allowing this terrible object constraint stuff is beyond me.
It’s crazy how good your tutorials are 🥲
Thanks Mario!
