A property replicates if its actor replicates and the property is set to replicate.
It sounds to me like what’s actually going on, is that the same code is run on all the clients, and they then end up each rendering the same thing. If you want them to see different things, make sure the camera they each render from is in different positions for each client.
alternatively you’re using a single render target asset, and running multiple clients in the same process, and they all use the same global object, which is a drawback of the “play in editor” way of testing multiple clients.
