Custom body mesh metahuman livelink error

Hello there. I have added a new body mesh to metahuman I imported it in UE and using control rig, everything works well. However when I am using livelink, the new body mesh fails to follow the face and it creates gaps between neck and the body. Same like in this tutorial: https://youtu.be/YNsNtpsCT4k?t=108

You can see the body doesn’t follow the head in livelink so there are gaps in the neck.

I didn’t change any name or hierarchy in the skeleton, so it’s all ue5 compatible. I think I only have to change my new skeletal mesh that I imported in Animations Blueprints settings, but can’t find any solution for now.

Does anyone know any solution to this?

Thanks in advance!
