In this video, I try to make the "Child Of" constraint a little easier to understand.

As noted in a comment by Sebastian Z, if you change the interpolation type of your child object's animation channels to 'constant' you remove the need for the extra keyframes to hold a position. Although then you will not be able to have a gradient control if you still want something like that.

@SlayerDUDE1993 Год назад

I hope blender devs will fix this "feature" soon, because after Maya's parent constraint it seems too complicated

@derpboi5526 Год назад

please I am dying in pain trying to make it work properly

Hi, Jhonny! Nice explanation, great to know more about this constraint! One thing I didn't see you mention is the little almost hidden "X" button, you will learn how to use it by reading it's tooltip. Basically, you need to insert a key before, and the keyframe after, using the "X" will zero the influence but momentarily keep the "visual transform" then you can key it normally.

@JohnnyMatthews 2 года назад

Great tip! I'd completely overlooked that button.

@pruttisman Год назад

Thank you so, so much! I've been looking for this answer for literal weeks, it's unbelieveable that no one else has mentioned it.

@brunosuraski5026 14 дней назад

Can you explain a bit more in detail how to use this feature and what will be replaced from the tutorial shown here? Although the instructions worked out well for me, I find it so overcomplex.

@WahranRai 3 месяца назад

It will be usefull to write down a step ba step script related to that

@fabbrobbaf 2 года назад

Thank you Johnny, sincerely, thank you! I must admit, I have never noticed those "visual keyframes"...Blender never stops to surprise me.

@JohnnyMatthews 2 года назад

Yeah I’ve only recently understood their value myself.

@PoMkAc27 3 месяца назад

Great tutorial, thank you. After 5 years in Blender now I understand what is the main purpose of visual transforms ))

Nice one thank you, solve my problem for now but I guess I will keep coming bck on this video till I fully understand it, bc around 5:52 my brain stop working

@illerhag 23 дня назад

My brain exploded. The child constraint is still as messy for my poor mind. Could they maybe implement a more straight forward solution?

@3d-illusions 2 года назад

Would it be nice to have an ‘apply child transform per frame’ option on the constraint to avoid this rigmarole? I can’t think of many situations where you’d want the child to use it’s original location during or after releasing the child. Or maybe the ability to key frame the interpolation mode between constant and linear etc.

@zaferec2354 2 года назад

I'm using an old method as this is too complex. I'm copying my object, and applying "parent" to one. The other maintainsing its fixed position. All I have to do is toggle the "visibility" between the two at the right time. For example, a hand holding a cup. Another method is to cook your animation. All you have to do is; delete keyframes where you want them to remain fixed.

@JohnnyMatthews 2 года назад

Sure! Do what works best for you!

@ryozun3041 Год назад

I am animating a guy who holds a Katana and when he is wielding while at it he then let go of the Katana then holds the Katana again, how do I do this? I have problems with the apply object method

@tirushone6446 Год назад

If you were to export the motion of the sphere as a fbx anim would it look like it does in blender or (due to the contrait on long applying unless you added it yourself in another external program) would it just teleport from the first location keyframe to the second (as per the dope sheet)?

@ShadowMakerSdR 2 года назад

This is - again - a very well thought out tutorial. Do you write these out in advance and then find the images to match them? You don't hear your mouse/keyboard etc but the footage and the voice-over match up really well.

@JohnnyMatthews 2 года назад

As far as keyboard noise goes, I use a close mic and RTX noise reduction. For the rest of it I have a rough idea what I’m going to record and do a lot of cutting out of bad takes in post production. But the voiceover is pretty much always recorded at the same time as the screen capture.

@ShadowMakerSdR 2 года назад

@@JohnnyMatthews even more impressive then. I can't go for two sentences without 4 or 5 uhms, so props to you!

@JohnnyMatthews 2 года назад

Oh, I edit so much, but I'm also getting better as I make more content. I actually have the Davinci Resolve editing hotkeys set up on my mouse to make editing faster.

@knerf999 8 месяцев назад

ok, so i would like the functionality of this modifier, but i need to be able to keyframe the target :( Any suggestions for a different solution? Like a hand on someone's wrist or an orbit around different objects in sequence.

@B-2-Z 2 года назад

I haven't tried it since I just stumbled upon your tutorial. But wouldn't changing the animation interpolation mode from linear to constant also make things easier? Meaning less effort on setting keyframes?

@JohnnyMatthews 2 года назад

That’s a great idea, I’ll try that

@zathuramon 10 месяцев назад

I tried you metod in a rig, but when i use the visual rotation & potition it messes up the potition, i dont know why it happens.

@adamszczesny2646 Месяц назад

Haha, cool.. Yet I still don't get why it goes bananaz if you "child of" constrain ik controller that has a root motion to an empty

@kaushalshelke5109 9 месяцев назад

still not working bruhh spent an hr on it , i also needed track object so i used it too will it have an effect

@marztecheque 11 месяцев назад

why does no one ever "apply:" the constraint? in the drop down beside the eyeball? when do you need to "apply" it? like a modifier, right? it wont' "take" maybe fully - until you "commit" it??? why is that drop down even there???

@cmto 5 месяцев назад

It definitely has its uses, but not really for this. More so for modifiers.

@ramilgr7467 2 года назад

Thanks! How did you zoom in on the interface in just one panel?

@JohnnyMatthews 2 года назад

Put your mouse in that area, hold CTRL and the middle mouse button. Then move your mouse up or down.

@jcrc1717 4 месяца назад

This is just too, too complicated for just a child of constrain. Blender devs will need to think seriously about usability some day. Artists need intuitive tools and do not want to thing about manual ui and the matrix math behind the tools at every key frame.
