Can I use Rpc Calls and Commands on the same object?

Hello everyone,

I created a multiplayer application for designing room. I want to be able to move non-player objects in both instances and I'm desperateIy trying to avoid using sockets (cause I'm terrible at coding ).

I know that Rpc Calls are used to send data from server to client, and Commands send it from client to server. I spawned this non-player object using SpawnWithClientAuthority but now I have 3 the same objects in the scene (I have only one remote client) and if I move one of it the other 2 objects are staying where they were.

Is there any way I can make it work without sockets?
