IS it possible to replicate DATA that does not exist on the client's side? PLEASE HELP!

Yes it would be streamed from motion builder into Unreal Engine in real time, it’s probably too big of an obstacle for me to take on, so I will end up having to go with an alternative method. I was just thinking it might be similar to how VR would replicate, but it must be easier replicating the handle orientations than just mocap data.
