UNET - Sync [ClientRPC] with new players

Hello,
i use a ClientRPC to hide the player and parent it to the car, if he gets into a car, this works to everyone which is already connected.
But if a new player joins, the “hidden” player is still parented to the car but not invisible

So how can i make it that the actual states are synced too (meshRenderer disabled)

Sincerely,
Global Hive

Solved myself, im just syncing a variable and if this is true then make the player invisible in the start method
