Sorry, I’m new to Unreal so the terminology is a little different. When I said the server owns the object I meant it is owned by the Actor that is controlled by the person who is running the server on their computer. Thanks for the definition tips.

That would imply this only works on a listen server, not a dedicated server. With 2 players max.

I believe your replication problem is because your object is set up incorrectly. Even Unreal’s replication doesn’t work with your set up. I think it’s because you are trying to replicate something else’s position and not the cube’s. Drag the cube into the level first and then put a blueprint on that and it will replicate the cube’s movement. Check out this post with relevant Unreal Stack Overflow explanation and a screenshot.

The object is setup as per the instructions in the provided documentation and does indeed work with unreal’s replication system.

I do not understand how you can call RPCs from objects you don’t own anyway. I don’t think anyone can just call an RPC on any object that they want without ownership.

That’s why you don’t use RPCs. An item in the world should not be owned. That goes against unreal’s design.
