How to play animation out of camera?

If a monster attack me, it will play a animation. But if it is behind me,out of my camera,the animation not really play. I attached a weapon to the hand of monster,at this condition,the position of the weapon will not change.I can’t get the BeginOverlap event. So how can I get the animation always play.

I got the method:GetMesh()->MeshComponentUpdateFlag = EMeshComponentUpdateFlag::AlwaysTickPoseAndRefreshBones;
