Change material in dedicated server

Well, I set up a dedicated server and can use multiplayer, but if i made a change in one window (for example change the material of a mesh) I can’t see the change from another window. But actually I can see the player moving, jumping or hitting other players.

What do I need to change the enviroment and has de capability to see the change in another multiplayer window?

Well, it was easir than I though… There is a large topic called “replication” that we (as not developers) didn’t know that exists. That topic solve every problem talking about sync everything.
