Thanks so much, this fixed this problem on my Unreal 5.2 project. I found through trial and error that not all of the fixes were needed, at least in my case. I had to name the armature object and armature modifier as "Armature", and had to select only the root bone, mesh, and the animations, and export with the "Selected only" option. I didn't need to name the root bone "Root". In Unreal, the animations looked broken, the model was incredibly tiny. Ticking "Enable Root Motion" immediately solved this, and I found if I don't want root motion, I can tick "Force Root Lock" which will fix the broken animations but leave root motion off.

Big thanks to you, Sir! you are so cool

Thank you for making this video, it didn't fix my problem directly but it was a great help. For most people this should just work, but sometimes it can mess up the animation direction if you change the name.

best video to fix root motion animation from blender

realy the best its simple but most import thing to respect name thing glad u did that

"Imported Bone transform is different from original. Please check output Log to see detail of error" Henrique Sales 讲师 Hi all, Here's what worked for me (Working in Blender): a) Setting scales to centimeters in blender with unit 0.01 b) Applying transform (CTRL + A) in object mode for both Object and Armature. c) Changing name of armature from "Armature" to to any other name

Thank you man, you are so cool

Big thanks to you, Sir!

Another solution that worked for me is to rename the armature to "root", and animate the armature object. Importing it like that has UE4 recognize it as root motion.

That's a pain to have to animate the armature object separate from the bones. But indeed it is a solution, just not ideal as you'll need an armature animation track separate from the bone tracks.

Another Important Setting: a) Setting scales to centimeters in the Blender with unit 0.01 b) Applying transform (CTRL + A) in object mode for both Object and Armature.

And remember to "apply all tranforms on your amature and 3D model, before exporting. i had a issue where it bend my meshes and wasnt correct.

when i apply scale my model explodes. The amature or rig to be more precise.

Hi. When I do root animation, the character does not move along the Z axis. What could be the problem? The skeleton is custom. I do animation in blender 3.5. or UE5, the result is the same. The root movement is triggered on the X and Y axes, but not on the Z axis.

No , don't do that. you need add a new bone witch is parent of hip as rootbone , and the new bone is top level. if you just rename , your character will fall into ground

@@smcfadden1992 no，if you want get animation from mixamo，you have to use mixamo skeleton.there are two way add a root bone. 1、add a new root bone after download mixamo in blender，or you can find out a addon for blender which named“mixamo blender root motion addon” from Google，then export as this video 2、just import mixamo animation without root to unreal，then use “ik retarget”tool the tool in unreal， retarget this animation to any human skeleton whatever it has“root”，but dont forget make rootbones location copy data from hips. i prefer 2，but it is hard to explain，you can search “unreal ik retarget” in KZread.

“Multiple roots are found in the bone hierarchy” i can't named armature as "armature"

Rename "armature" is not the key point， the key point is “The entire object itself is its own root bone”

好明显的中国口音啊大佬哈哈

That's freakin bullshit , first off , I got my Root bone renamed Root, and I made root bone as it has to be or IDENK, so It doesnt work, dislkike , sorre
