Copy Player moves, to possessed Pawn.

I can’t wrap my head about one thing. I want to copy Player moves, to possessed Pawn. And control 2 characters in the same time with one input. Best case, that I can recall - In blade runner 2049, there was a sex scene (nothing obscene). Real person + hologram sync their moves. Holographic Sex | Blade Runner 2049 [Open Matte] - YouTube Any direction on the right track of thinking will help me a lot.

By copy moves, do you mean animations?
If that’s the case, you can duplicate and retarget every animation asset to the skeleton of your pawn, then duplicate your character blueprint, together with it’s inputs and codes, then set it up as a new character that can be possessed

I can do it with no problem, but when i possess secondary (pawn) character - I control only one character. Is there a way to control both of them simultaneously?
