Animation Retargeting In UE5 | New IK Rig Retargeting System (Tutorial)

Hey guys, in today's video I'm going to be showing you how to use the new animation retargeting system in Unreal Engine 5. This is using the IK rigs and retargeting. The example in this video is using a Mixamo character and animation, however this will work for any character, skeleton, and animation you want to use.

Thank you! I was so confused when i tried to retarget the UE4 way in UE5. This is definitely more complex so im greatful for this tutorial.

[@simi7272]

This worked! Way better than downloading a certain bloatware app for my PC. With this, everything will work just fine!

[@samohickey]

Awesome! I'm so used to the one in UE4. You made this a cake walk on UE5. Awesome tutorial! Thank you.

[@Ruebler1]

Excellent tutorial, your tip where you said smth about choosing the pelvis as root bone probably saved me hours of being confused!

[@GAMEBR0VIP2462]

Holy Smokes thats actually way powerful , just with the legs arms spine and head that youve done here . ive got the entire RPGV4 system to work with Custom Character Creation Man and Female . insane . Awesome Tutorial Thank you .

Awesome tutorial, straight to the point, good pace and very clear with the instructions. Thank you!

[@thestellarelite]

Thank you for this really clear tutorial I finally understand more what I'm doing because of this instead of blindly following I could actually go off on my own and do a Daz character to Mixamo. Thank you so much!! Although she looks a little janky in the arms I think it has to do with Daz's "twist" thing in the arms and legs will have to run off and troubleshoot that. So happy been at this for months honestly lol

[@swinny_]

Great tutorial on this new feature. IK Retargetting is eons ahead of the old system, Fantastic

[@pedroricojr]

Thank you!! Just spent 2 hours trying to figure out why my character was flying around instead of copying the animation. You pointed out that the pelvis had to be used as the root in the IK Rig and that fixed it! Thanks again!

[@MattAspland]

Happy to help! :)

[@TorQueMoD]

Great video! A faster way to do the chains is to select the bones in the Hierarchy and then click the Add New Chain Button and the retargeter will name the chain and detect the starting and ending bones automatically. Just make sure you don't select the Twist bones. For fingers it will create one chain per finger. Also, it will pause for a few seconds when you do longer chains. Don't worry, it's still working. Takes about 10 - 20 seconds tops.

[@PIPOXO]

I was watching another video on the basics of creating animation chains in Unreal as a beginner, until I wasn't able to retarget the old way and found your video, which has been very clear and easy to follow, so thanks. But now my mesh will not select to move for adjusting the pose using "edit pose". I'm super new to the engine and have no idea where to even start looking for troubleshooting.

[@myleneohara6623]

Hi. Exactly what I was looking to do ! Thanks !

[@TrojanLube69]

Quick tip, if you are using ue4 or ue5 skeleton structure: you can also duplicate the ik retargeter inside Third person template and use it on your skeleton. For mixamo, you have to create your own but you could still duplicate and use it just changing the bones names from mixamo. Makes it way faster and easier to do this way.

[@WesleyOverdijk]

I just did this and swapped out the target, good tip! Saves you from manually mapping everything and allows you to just follow the manny rig as closely as possible.

[@Cronosonic]

Just a quick tip to folks also learning how to use the IK Rig retargeting system - if the root motion is coming from the 'root' bone rather than the pelvis/hips, make sure there's a 'root' chain mapped out on both IK rigs, select it in the retargeter, and set the translation mode of the root target chain to "Globally Scaled" or "Absolute". If you don't do this, no root motion data will be actually be retargeted. This is vitally important if you plan to use root motion as part of a character's actual movements - make sure the animation's root motion will be retargeted properly before you start retargeting animations en-masse, it'll save you a lot of time and headaches. (Also, use the bulk property inspector to turn on root motion for all your animations at once.)

[@scarecrowhobo]

not to sound like an ass but can say this in unga bunga?

[@CaseyChevalier]

For the root chain, did you set root as the start and end bone?

[@sebastianbryant4216]

Thank You!!

[@edwardpm89]

@@CaseyChevalier Yes, just right click on the root bone on the skeleton tree and choose New Chain from bone and click Okay without changing the names

[@showreel2011]

Thanks

[@KEEKSPLAYS23]

Love the video. Can you make a video about saving and loading audio settings?

[@Madmonkeman]

The reason setting the pelvis in the Unreal mannequin works better than the "root" is because Mixamo doesn't have that extra "root." The root controls the overall position the skeleton is in, so if you set the root retarget on "root" for Unreal mannequin then the mannequin will move around the screen.

[@rocketpoweredchimpgamesphi7798]

Very useful, got almost all the way through, only to find the model I wanted to use to retarget TO was MISSING a whole right leg in the skeleton lol! Oh well! He must have been out the night before and came back legless! (bad joke, I'm here all day lol)...

Hey. your videos has helped me alot learning how to use UE4. And would like to ask, if possible to make a video on how to make a Wave based system, which is endless, but with different enemy types? So like all waves have a base enemy, but like from wave 20 a harder enemy appears along side the base,?

[@blackpara_music6346]

loveyou!

[@Leomerya12]

Thank you! The solutions on the UE Forum were terrible!

[@megtwin]

SOLVED: I have been trying to retarget Manny's basic anims to my own character. All of them work great with the exception of the Land animation. Its always 90 degrees off and when its used in game it gets really large when playing the land anim. Do you know how to fix this? Solution: If anyone runs into this issue, go to your characters land anim and in the Additive Settings set it to None.

[@Winterizes]

if people are still using this method today, you can mirror a chain when setting up the legs or arms for example and it will automatically map the chain using the L or R bones for you. Just right click on whichever chain you created (Such as Arm_R) and then mirror the chain (Will create the Arm_L for you)

[@PiterTraceurFA]

for some reason, while root motion works fine while using root bone, the pelvis only rotates, but doesn't move

[@CommanderColson]

Thank you as always for another great tutorial. Could you do a video on a simple train system? Example- you have a platform moving on a spline-circle. However, the platform comes to a full stop at the 12 o clock and 6 o clock points of the circle. After a short bit, it begins traveling again. Thank you!

cool video thanks but hey so just rotating the upper arms to a tpose only fixes the upper arms, the lower arms , hand and fingers are all at the half way point of their rotational range, surely you need to zero them all out to get a precise retarget, I can see the forearms are at incorrect angles.. Is there a quick way to get the target character to a proper tpose (like a metahuman for example?) thanks!

[@danico.8520]

Hello, quick note if you are having an error with the root motion. I was making a game on UE4 so I was basically retargeting UE4 character a little bit modified and I did everything perfect but the root motion wasn't workin... the thing is that you cannot add "pelvis" to a "chain" if it is the reference for root, leave your reference root not attached... now I understand why but it was annoying those 30mins trying to find my error without noticing that little mistake

[@RiverFox_YT]

i have the survival game kit V2 and im trying to retarget a character from marketplace to the ue4 mannequin built in to the game kit but i keep getting a weird problem where the arms keep stretching out like a monkey, any one have any ideas? i also seem to have some additional bones called upper arm twist and lower arm twist.

[@arnoldsoko]

🙌🏿🙌🏿

[@nikgiak2994]

Awesome ty Matt! Is it possible to make a very detailed video on how to optimize UE5 as much as possible, to perform better? Personally, I don't use UE5 yet since its so demanding (or problematic) that I lose 50+ FPS compared to UE4 on a clean project (viewport or packaged with all the fancy stuff disabled).

[@diliupg]

You can gain that 50FPS back again by simply switching LUMEN OFF and SHADOW MAPPING OFF. With these on if you want higher FPS on existing system you need more GPU power and RAM. UE5 is supposed to be for High end production so starts off on a higher spec requirement.

[@NuronAtren]

You say long winded but what is the alternative? This retargeting is pretty awesome.

[@visiochannel2]

If problem / set new root target .for one of the characters . in example quinn .

[@VisQo-Herold]

Thx M8 :)

[@nicolajesteban9211]

do you know if this would also work to increase the motion. like I have a rokoko suit and when live streaming to the characters the motions seem to be translating only a little. like when I do a full hip swing the character seems like he's only swinging the hips a tiny bit. would love to get your thoughts on this :D thank you!

[@AMobOGobos]

Great tutorial; this one helped a lot! I spent the time to retarget the fingers (I am going from UE4 mannequin to mixamo Y_Bot), and the target skeletal mesh doesn't curl its fingers like the source does. Any advice on how I could fix this?

I have the same issue. Did you solved it?

[@jeremyjquinn]

OK, I was able to get a downloaded character to create the animations in preview, but cant figure out how to then use that as my player character? Is there a final step to then set up the player character using the re-targeting that was created, or am I missing something?

My fingers are all messed up. Any idea how to fix them? I'm using 5.3 Thanks

[@Hato1992]

Not working in 5.3.1. Animation in retargeting is correct, but when I open exported animation arms are totally wrong animated. Tried with T-pose and A-pose, both are not exactly right. @Edit: After retargeting again it worked. But I had to create T-pose as "Pose" from animation, then set it for target skeleton in retargeter.

[@sirgwindortvinuel]

hey matt! i have question but it is not related to this video. The question is i wanted to add sliding to my game(which is my homework) i got the animations and all that and i started watching your video, I opened the animation and it was working perfectly. Then i had to make the animation in place so i opened root motion. BUT when i enabled it my animation looked like it was jumping instead of sliding. I even commented on that specific video and if somebody answers how cani do a in place aniamtion with out it turning fricking vertical.
