IK Rig Retartgeting First Person Animation do work

Hi There, I just getting start with UE 5 Animation Rig. I am trying to retarget some animation to Lyra UE4 Skeleton. So, Created animation rig for other animation skeleton mesh. Then use IK retarget to convert the Animation.



It works very well with third person model.

however, no matter what I do to change the rig. It do not convert the first person animation. The hand and arm are not in place.

Is there any thing I did wrong? Thank you!
