This is my current character workflow for games in unreal engine. By default, Mixamo animations do not have a root bone which makes the root-motion animations unusable in Unreal Engine.

Hello, Thanks for the video. Still, i am running into more errors. I am using external mesh, but i am using Mixamo animations. Everything seems good before running it through the Belnder plugin, but after that, my animation seems to be messed up in a few of them. I am not understanding what I did wrong.

Great tutorial. Thanks for it. I'm having an issue when retargetting the animation to another character : Thanks to the added root bone (from the Blender plugin) and Root Motion feature enabled, the original animation on the source rig works fine (characters runs and slides in place), and it works in the Retargetting menu as well, it shows the both the Source andTarget rig and character have Root Motion correctly applied. However, when you export the animation (from the Retargetting menu) and use it on the Target rig/character as stand alone, it seems the Root Motion feature doesn't work anymore, even when enabled. Using a Head/Arms/Spine/Legs IK chain. Including the Hips/Pelvis bone of both Source and Target as an additional IK chain during retargetting seems to fix the problem, however the animation gets very wonky as a result. This is a very annoying issue. Would you happen to know a work around?

Thank you! It seems like the root motion is not being correctly transferred. You can try using the "Additive" mode when retargeting the animation. Open the Retarget Manager by selecting Window > Animation Editors > Retarget Manager. Select the animation you want to retarget. In the Retarget Manager, select the "Additive" option from the "Mode" dropdown menu. In the "Additive Settings" section, select the "Enable Root Motion" checkbox. I think the issue is with the translation mode of the root target chain. Test out different options like "Globally Scaled" or "Absolute". I hope this helps.

nice and easy tut. thanks. I want to know like i found that UE mannequin have many different bones and i tried chain retargeting with mixamo animation to UE mannequin but it does not turn out to be working like its going weird. I a designer. so do you think that because mannequin have more bones than mixamo thats why it doesnt work? thanks.

@openreality0 Год назад

Thanks! When you retarget, make sure that they both have the same pose. Unreal mannequin has an A- pose which you will have to edit to match Mixamo pose. Also if you're doing this with the converted animations that have a root bone, you will have to make a root chain on both the ik rigs. Let me know if this helps or I can point you to few tutorials that could solve your issue.

@@openreality0 thanks for the reply. i will let you know.

After I turn on root motion, absolutely nothing happens, I already have the same bone heirarchy as UE5's one, also with a root bone. I can't get over this problem... My root bone is Hip bone, but the UE5 recognizes the whole character as the root bone which can't be animated, what a stupid thing Unreal Engine does, please someone help me!

Hello ! Nice tutorial but... I'm blocked to 3:07 of the tutorial, When I import mixamo animation, my Y BOT, stay in T-pose when I open the animation... How can I fix it ?

@openreality0 Год назад

Hey, first import only the skeleton like shown. Then when you import an animation, make sure you are selecting the Y-Bot skeleton in the import options. I think you're having an issue because of selecting the wrong skeleton during import. Let me know if you still have any issues.

@lemeilleu_ Год назад

@@openreality0 Yeah :) Really thanks it's work ! (I forgot to uncheck "import animation" when I want to import skeleton... I also needed to press the "Reset to default" button when I imported the animation and it worked!)
