Your video helped me solve a problem i had, very concise and well explained! Thank you!

[@hotcher2]

This is the clearest and simplest explanation I've seen. Thank you!

[@gugacolman]

awesome video bro

[@yasharmosaffayetabrizi7055]

Can I use this for real-time VR body-tracking?

[@bestplayern1ytrox321]

Thank you so much! But do you know how can i make that a IK in attache to a 3d Objekt ( for example a cube ) so that if a move the 3d Objekt i also move the IK. 🧐

So if you create a recoil animation for a pistol and put that pistol in a socket in Manny's hand, his body will react to the recoil animation?

But how to implement this in sequencer animation. there is no tutorials

[@thegamedevcave]

for that you'll want to use control Rig, it's a bit more involved of a process to set up but it allows you to animate your skeletal meshes quite nicely. I've got a tutorial on that coming up pretty soon but you should also be able to find some go do stuff out there on KZbin already!

hi, can i use this in real time ik?

[@TheSynan]

Weird, it won't let me select a skeleton when I ad an IK rig. My version must be different?

[@hiQer]

Same here and I fidn this issue on the forum on reddit etc. But no one knows why this happens. It seems that when you add a preview it work good enough. But it does not ASSIGN the skeleton to the rig..So this is an issue I believe.. The problem is there sinds many months.

How can I integrate this with ctrl rig? I have a ctrl rig set up but the rig moves all bones, which isn’t what I want, whereas IK ctrl has the set up structure I need but I have to animate the rig

[@thegamedevcave]

this IK rigging is mostly what is used to retarget (or at least, it was before auto retargeting become a lot more powerful in recent updates) this is separate from control rigs. here's a video about control rigs ": kzbin.info/www/bejne/rqO9noB_Zsyelac and a video about the new modular control rigs in unreal 5.4 : kzbin.info/www/bejne/gKSqY5WofNGYrNE

Please please help me. I want to use Unreal 5 to animate with and render because its amazing. BUT my rig was in FK so I followed this tutorial to make it an IK, and I came to a huge problem. How do I actually use the IK rig? I see no option in the "IK rig blueprint" to animate or keyframe, so I assume to animate with it you would need to go to the Level Sequncer, but I can't figure out how to get the IK rig into the Level Sequencer. Can you please help me?

[@thegamedevcave]

you're looking at the wrong thing for that, you need to setup a control rig for that, this IK rig is for retargeting and i believe it also helps with real time IK. for anothion you need to set up a different kind of rig, which I also have a video on kzbin.info/www/bejne/rqO9noB_Zsyelac

[@zorgandfroggo]

@@thegamedevcave Thank you so much, you are the only person who has answered my problem. I will take a look, thanks.

[@nucleusart528]

OOh thank you so much! i been all over internet trying to find a solution to this. allot of loong unprofessional misleading video's out there BTW *IK rig* is moved under animation / Retargeting now

[@scislianlongshadow]

Dude im with you up till the point where you say "see you can move the arm" and I CANT the control just moves around no arm movement

[@DieGo-yt9zt]

What can I use IK Rig for?

[@thegamedevcave]

These rigs are mostly used if you want to take animations from 1 skeleton and apply them to another skeleton.

[@ATomCzech]

This looks easy, but I still don't understand the relation between this IK Rig and Control Rig. Control rig looks very similar too me, you have a visual marker and then you need to create own logic to change the pose based od visual markers. IK rigs presented in the video looks like simplified version, you jus set some predefined solver, but how thy now how exactly is possible to move for real human to look it natural? When I should use IK rig and where Control rig?

[@thegamedevcave]

they do overlap a lot, personally I am also more familiar with control Rig. Setting up a full IK rig is also needed for retargeting animations between different skeletons though, and from what I gather, it's more meant for real time IK on runtime (although control rig can also do that with animationBPs I believe) In general, this is a nice quick option but in most cases you are probably best off setting up a control rig instead.

[@ATomCzech]

For example for pusgh button animaitons, where character need to move hand to exact position, IK rig is always used.

[@coolorphans]

I don't think the unreal dev community respects my time. I see there are solutions on videos already but no packages I can import? I mean great, the creators want to get some money by advertising their patreons. But come on, just show the video, have the package, and advertise your patreon. I'm not trying to reinvent the wheel.

[@thegamedevcave]

I only link to my patreon with project files when a video contains something that was actually created, in videos like this i am just showing off a feature so there isnt any project files to share.. i am not going to make people pay for what is essentially an empty project
