Root bone fixed when retargeting

[romeo_juliet (로미오는줄리엣)]

Hello. I have some issue with animation re-targeting, especially moving root bone.

When I re-target animation, it looks like successful. But when I tried to using motion matching, the character motion not changed from idle. Then I found something strange. At walk animation, source skeleton’s root bone is moved. But my skeleton is not.

1. Pictures with re-targeting

(Target) Root bone not moved.

(Source) Root bone moved.

2. Some additional information

• My character model
  “Hayakwa Aoi” at booth (【オリジナル3Dモデル】早川葵 - WARPSTORE - BOOTH)
  The charactor targeting for Unity, espeically VRChat. But creator provide Blender file. So I export fbx file by using Blender.
  

  

• Reference video
  I watch https://youtu.be/YuIUrKNw52M?si=RMZTZqfiaRwpqs9M&t=622 10:22 to 21:48 and try also, but not works.

What should I do?

I solve this problem my self.

1. Make root bone in blender is not required. Just rename Armature object ‘root’
2. Change some details in root chain. Look at the video https://youtu.be/23q_mPx0dbQ?si=KDtNEFahLOwrWoho
