let someone else's helmet and his helmet overlap

When online, Calling call other people to himself position, let someone else’s helmet and his helmet overlap, others helmet angle and his helmet angle. May I ask how to achieve?
I’ve already done it:
pawn BP:

GameMode BP:

This effect is client calling the server no problem, but server calling the client is wrong position. Excuse me, where is the problem?

I think you only achieve locomotion sickness. You see all those packets travel long distances and this will cause locomotion sickness for sure if you try to replicate helmet location. Even if it was not the case you basically move one players camera, it is just invitation for trolling (for rg. remove helmet and spin fast with it or drop fast to floor level etc.). This setup just begs for troll.
