Lets say i want to show tooltips/information about objects in 3D world. The item is on the floor, ok so i attach a node to the item in 3D world that shows info about the item. But then this visual info node "tooltip" is going to be visible to every player instance, right?

One way i think is to have the visibility of the node mesh (if its even possible for Label3D) be set on some other layer than other players, for the Camera3D layers i mean.

But there were limited number of layers.. At some point you run out of them layers, right?

Another way would be, i assume, to use control nodes? Then do the meth calculations for displaying text in 3D space over a 2D plane in the control node or something?

Maybe use SubViewports but i dont know how they work in multiplayer scenario. Do they work on per Camera/player basis or are they visible to all 3D cameras/players?

I haven't built the test chamber so far to test the multiplayer capabilities, but thats not too far on my radar.
