UE5 preview 2 Retargeting with Full body IK solver

[@vickylin9600]

Thank you! This is exactly what is missing from countless UE5 redirection tutorials!

[@vickylin9600]

Can you make a detailed tutorial on IK Rig Solver?

[@vickylin9600]

Can you tell us why "root" need to be set for full body IK solver? Why not Pelvis?

[@user-kq6uz9qm5g]

This is the best tutorial on the new IK retargeter! Compared to other tutorials you went more in depth to cover the issues and solutions. Please look into the different IK solvers maybe a few limb solvers might be better than a full body IK.

[@GUMLIVES]

Sure, there is a lot of other solvers to explore. I bet there is a lot to automate with those.

[@TUSH4R451]

Agreed this is the best!

[@vickylin9600]

hear! hear!

[@mx-gamesdev8287]

By Far the best explanation for retargeting Thank You.

[@GUMLIVES]

You are welcome!

[@yearight1205]

I LOVE YOU!!!!!! MAN I LOVE YOU!!!!!!!!!!! I have been sitting here so incredibly angry for a LONG TIME, because I was setting up the ROOT for the movement of the character. I didn't know it was the Pelvis. I'm fairly new to Unreal Engine, and have been insanely frustrated because I am using it for short films and animation stuff, not for video games. PLEASE keep making videos!!!

[@GUMLIVES]

You are most welcome!

[@snowbeat936]

The only updated tutorial that works, +1 thanks bro.

[@GUMLIVES]

Thanks to you!

[@Thinksee3d]

This is so useful. Thanks for this! Couldn't find any of this in the UE documentation.

[@GUMLIVES]

You are welcome!

[@johnkopp-v8e]

It was very difficult because I didn't know about the blend to source function. it worked out thanks to you

[@GUMLIVES]

YEY!!

[@Desh681]

Can this work by, after you set this up, you can share skeletons and it'll keep all settings? Or do you export animation each time?

[@naza0777]

you are explaining so good really thank you for your effort..

[@GUMLIVES]

Ty so much!

[@DominoDevRandPrimeNum]

Great tutorial! thanks for sharing.

[@GUMLIVES]

You are welcome!!

[@FF-FAN9999]

Any reason you didn't include the twist bones in the targeting? Wouldn't it make the animations more accurate ? Would love to know

[@jubano3747]

Thanks for the video! How to set the new retarget character as playable character after that? I'm supposed to call the BP_Animation for the source? My retargeted character is not animated after all of this in the game!

Sir i have a question I have a single bone for my weapon to attach to in my rig. it has no ik or anything its just a bone floating.when i import my old rig and animations it works fine but when i retarget it, it doesnt work. it stays on the floor but rotates as the animation. how do i fix it?

[@deygus]

I am confused, can you help me understand your mentioned don't be fooled by the root at 4:10 roughly when setting the root to the pelvis and not the root bone? That's a little confusing as to why that's the mentioned case since that's labeled bone-wise as root.

This is getting a lil bit old, I should soon do a new one for 5.1

I have major issues with the spine no matter what I do. Whether I use the IK or not my character is bent in half with most animations.

[@michaeltello9619]

Please do a Metahuman one for preview 2. i cant figure out how to get the preview mesh to show completely. I only get the hands and feet. thank you!

[@GUMLIVES]

I will!

[@GBTC2011]

How do you retarget the fingers?

[@GUMLIVES]

Same, you create chains for each finger and toe.

[@tatevikavoyan7216]

amazing tutorial. Thanks a lot.

[@GUMLIVES]

You are most welcome!

[@MindOfBoomBoom]

As a beginner, this was a really helpful video. i've been struggling with feet movement, also didnt know about the root being an extra bone in the control rig. what was the name of the female figure? would you mind putting that as a link in you description? also for the MCO mannequins would be great!!

[@GUMLIVES]

She is the Belica Paragon Character, she is free in the Epic Unreal Marketplace

[@MindOfBoomBoom]

@@GUMLIVES thank you!!

[@MohdZuhair-Personal]

thank you for the tutorial

[@GUMLIVES]

Thank you! Hope to see you soon in next year live streams!

[@tuatec]

Thank you so much for explaining the IK solvers! Most tutorials don't cover this step ... How would you retarget the fingers?

[@GUMLIVES]

After you have your body moving correctly you can continue creating the rest of the bone chains for the fingers. Simply select the base bone of each finger and shits select the tip and create each chain. It really won´t take you too much time, once you do a couple you will get faster and faster. Cheers!

[@kingsleyadu9289]

Please can the hands be close as ue4 mannequin

[@qudratkhan6403]

make chain for each finger too on rigs.

[@GUMLIVES]

The answer to this can be a video on its own, i will respond as soon as possible.

[@abhimanyubundela2568]

Hey there, Really amazing tutorial but I have a Question regarding Importing Paragon Characters in UE5. Because when I'm importing the Belica or any other, the materials are not loading for most of the Skins. Maybe it's because of Material Function or something or I just need to recreate all the Materials using Textures? May I know how you did that plz. Thanks in advance

[@GUMLIVES]

That Belica I imported in UE4 and reused that project as a UE5, so i really didn't import her to UE5, let me take a look and ill get back if i see any issues, thank you for the heads up!

[@abhimanyubundela2568]

@@GUMLIVES Yeah plz, because for me none of the Materials of any paragon character is rendering. Getting grey material for every one of them.

[@qudratkhan6403]

Amazing tutorial, You explain alot in 18 minutes. But can you guide how to share ik retargeter asset with other skeletal meshes for example Belica has 4-5 skins how can I apply same Ik retargeter to all of them.

[@qudratkhan6403]

Never mind a stupid question :D, solved it .

[@GUMLIVES]

Hee, all skins use the same skeleton ;P

[@qudratkhan6403]

@@GUMLIVES thanks for reply, Still facing some issues retargeting ik bones. Foot ik and hands ik. I would really appreciate any help regarding this issue.

[@Tenchinu]

amazing tutorial! but I'm encountering a problem with the rig, since instead of using the UE avatar I imported it from Blender. Do both rigs need to have the same number of bones for it to work? It mimics the animation perfectly until I add the IK

[@GUMLIVES]

Nope, both can have diferent number of bones, what is important is to name your chains correctly.

[@FunnyFavor]

Fantastic video, just what I was looking for! (For a while, I might add) I did have a question about where you obtained all these animations from? Where they in a pack of sorts? Thank you!

Anyone asking about fingers just have to make chains for each finger also, index01 - index03, middle01 - middle03, ring 1-3, pinky 1-3 and thumb 1-3 for both hands

[@GUMLIVES]

Exactly!

[@McHornet7]

cause the root motion doesnt work?

[@GUMLIVES]

Sure does, the tool got much better with the last update. Gotta update this video in one Live.

[@dball913]

Every time I try to export the animations, it crashes. Any idea why this is happening?

[@GUMLIVES]

Any particular set of characters that i can test on my side?

[@dball913]

@@GUMLIVES Thanks for the reply! I am using the standard Y mixamo character and I am trying to retarget several of the mixamo animations to a Metahuman character. They look great in the preview. However, all of them cause the program to crash when exporting. I found that by NOT including the fingers, the export works fine. I am assuming that this is a bug.

[@GUMLIVES]

Have you tried this? kzbin.info/www/bejne/eYHGZpafg5d1qa8

[@ziocletouk]

I'm having the same exact issue, did anyone here manage to find a workaround?

[@VoidRose]

Fingers?)

[@GUMLIVES]

Same old, more chains. But now with 5.1 is a lot faster!
