World Viewer

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 void, so the edge of your download is obvious at a glance.

Features

  • Automatic download. On by default. Join a server, start moving, and every chunk the server sends is saved as you load it. A small status indicator shows at the top of the screen.
  • Live download map. Press M to open it. A 3D voxel view of your downloaded world plus a flat 2D top-down map (toggle with V). Brightly coloured chunks are saved to disk; dimmed chunks are loaded but not yet saved.
  • Two cameras. Orbit (right-drag to rotate, left-drag to pan, scroll to zoom) and a free-fly "drone" (WASD to move, space/shift for up/down, drag to look, scroll to change speed).
  • Area selection and export. Pick a box in either view, then save it as a clipped Anvil region or a .schem schematic. You can also save everything currently loaded around you.
  • Real, version-correct saves. Chunk data is written with Minecraft's own serializer, so palettes, biomes, heightmaps and lighting are byte-exact and the world opens normally in singleplayer.
  • Multi-dimensional. Fly through a portal and the Nether and End are written into the same world.
  • Configurable. Auto-download, 3D detail capture, anti-aliasing, detail range, field of view, look sensitivity, a rebindable open-map key, and the save folder. All saved to config/wdl.json.

Commands

Command / key What it does
Press M Open the map (rebindable in the settings panel or Controls).
/wdl save Force-save every chunk currently loaded around you.
/wdl auto on / off Toggle automatic downloading.
/wdl detail on / off Toggle full 3D voxel capture.
/wdl output <folder> Set where worlds are saved (blank = .minecraft/saves).
/wdl settings Open the settings panel.
/wdl status Show state, saved/loaded counts, and the output folder.

Requirements

  • Fabric Loader and Fabric API
  • Use the download that matches your Minecraft version. Builds are provided per version (currently 1.21.8 and 1.21.11).

Good to know

These are inherent to any client-side downloader, not bugs:

  • You can only save what the server sends you, i.e. chunks within your render distance. To download an area, go there. A higher render distance loads more at once.
  • Container contents are usually empty. Servers do not send chest/barrel inventories until you open them, so most containers download empty. Signs, banners, and similar block data are saved.
  • No entities yet (mobs, item frames, paintings). Blocks, block entities, biomes, and lighting are saved.
  • Respect server rules. Many servers forbid world-ripping. Use this on your own servers, in singleplayer, or where you have permission.
