Inmis Multiplayer and worlds

Backpack contents are stored on the item itself, so they travel with the item: drop it, put it in a chest, or hand it to another player and the storage goes with it.

On a server the mod must be installed on both sides — the server owns the backpack inventory and the client draws the screen and the backpack on your back. Config values that affect gameplay, such as tier sizes and the blacklist, are read from the server's config file.

On death, inventory backpacks spill their contents by default so nothing is lost inside an item that might despawn; a worn backpack keeps its contents unless you turn that option on too.
