MetaHuman Retargeting Issues in Unreal Engine 5.8

I’m currently facing an issue with MetaHuman animation retargeting in Unreal Engine 5.8.

When I retarget animation to a MetaHuman, the body animation is working, but the finger/hand movements and facial animation are not being transferred correctly.

The main issues are:

  • Finger animations are not retargeting properly.

  • Hand and finger poses become incorrect after retargeting.

  • Facial animation/data is not transferring correctly to the MetaHuman.

  • The same workflow appears to behave differently compared with previous Unreal Engine versions.

Has anyone successfully retargeted full-body + finger + facial animation to a MetaHuman in UE 5.8? If so, could you please share the correct workflow or any required IK Rig, IK Retargeter, MetaHuman, or Control Rig settings?

Any help or working setup would be greatly appreciated.
