Export Morph Animation from Maya and Blending it with Unreal Sequencer not working.

I have added morph targets in maya using ARKit and it is working fine. I imported it in unreal engine and it is working fine in UE too.

I want to do a sequencer animation for cut scene rendering now when I add my avatar in sequencer and add an animation of talking it is working fine but when I add another animation of morph targets it is blending bones too. I just want face morphs work and don’t want body bones animations.

I am new please help … stuck on this for 3 days now.

Any Expert?
