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!

Who here hates constraints as much as me? 😂 🔥 On another note, our Blender Basics course is now LIVE! ⏩ If you're an Animator who's been wanting to learn Blender, we've made this comprehensive course for you www.toanimate.ca/

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

@reeanimationgaming1034 10 месяцев назад

Holy shit.. I didn't know about the "child of".. I always tried to use "copy transform" which is just completely random.. Thank you!!!

@BrianKouhi 10 месяцев назад

Haha It's always the little things that are helpful and easy to miss

@EvertonSchneiderS 2 года назад

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. ;)

@BrianKouhi 2 года назад

Noted! That would definitely save some time, I'll test it out.

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?

@leatherandpoemscharmyman5774 2 года назад

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.

@AdrianLignos3D Год назад

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.

@RunorDieyt 2 года назад

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

@BrianKouhi 2 года назад

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.

@ramezmahdi1818 2 года назад

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? 😅

@BrianKouhi 2 года назад

😅 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 😁

@BrianKouhi 2 года назад

Haha I can only imagine! happy to help 😁

@zecle 2 года назад

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 ?

@BrianKouhi 2 года назад

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 🥲

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 ?

@BrianKouhi 2 года назад

Did you set keys on location, rotation, scale before constraining?

@xomeep 2 года назад

@@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 ?

@BrianKouhi 2 года назад

@@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.

@rexwinz 2 года назад

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.

@BrianKouhi 2 года назад

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.

Constraints in Blender is a breeze compared to Maya... there was ALWAYS something going wrong with Maya constraints.

@BrianKouhi 2 года назад

Ain't that the truth 😂

@jinchoung 3 месяца назад

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.

@drguerrou417 2 года назад

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.

@nashk935 Год назад

This is totally wrong way. U should do it with copy location and copy rotation. No need to parent reparent.

@BrianKouhi Год назад

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?
