World Downloader

by KuudraLoremaster

World Downloader saves Minecraft worlds that a player explores on multiplayer servers to a local folder, so they can be opened later in single-player.

FabricClient required, server optionalMIT License1.21 – 1.21.10

What it does

The mod copies the parts of a multiplayer world a player has loaded into a folder on the client. Once saved, the copy can be found in the saves folder of the Minecraft directory and opened like any other world. Coordinates such as 0 0 -1000 can be visited in the copy to view the chunks that were saved. Entities, item containers such as chests and furnaces, and other container data are not saved. Only the client needs the mod, and the server can run without it. Fabric is the only loader, with a 1.0.0 file for 1.21.10 and builds covering 1.21 – 1.21.10, released under the MIT License and not open source.

Key features

  1. Saved server chunks

    Terrain the player has loaded on a multiplayer server is written to a local world copy.

  2. Local copy in saves

    The saved world appears in the saves folder and opens like any single-player world.

  3. Terrain only

    Entities, chests, furnaces and other container data are left out of the saved copy.
