World Viewer
by Kalpe
World Viewer lets a player explore a Minecraft world from a map view, and saves the chunks the server sends into a normal world folder.
What it does
On a server, the mod takes the chunks the server streams to the client and builds a live 2D and 3D map from them. Areas that have not been visited stay as void at the edges, so the unexplored parts of the world are visible at a glance. Moving through an area fills in the map, and the count of collected chunks is shown on a small status indicator at the top of the screen.
Saved chunks are written with Minecraft's own serializer, including palettes, biomes, heightmaps and lighting, so the result is byte-exact and opens as an ordinary singleplayer world. Players can fly through the Nether and End portals and have them written into the same world. Builds are provided for each supported version 1.21.8 – 1.21.11 and 26.2, and the build matches the Minecraft version in use.
The mod requires Fabric Loader and Fabric API. It runs on the client alone, so only the player needs it installed. It is released under the MIT License and is not open source.
Key features
Live map view
The map shows the world from the collected chunks, in both 2D and 3D, and updates as new chunks arrive.
Two cameras
An orbit camera rotates with right-drag and pans with left-drag, while a free-fly drone moves with WASD, space and shift.
Area selection export
A selected area, or a clipped Anvil region, can be saved as an a.schem schematic from either view.
Automatic chunk collection
Joining a server starts collecting the chunks it sends, and saving everything loaded around the player can be done in one step.

What the author says
World Viewer is a client-side mod that saves the chunks a server streams to you into a normal Anvil world you can open in singleplayer, and shows you a live map of exactly which chunks you have downloaded, not just a count. As you move around, the area you have explored fills in. Places you never visited stay as…
