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
Mto open it. A 3D voxel view of your downloaded world plus a flat 2D top-down map (toggle withV). 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" (
WASDto 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
.schemschematic. 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.

## World Viewer 0.3.0 - Saving update
Three separate bugs could each make a save look like it had failed when the data was actually fine.
If you have a download that opened as empty void, or a `.schem` a server rejected, it was probably
correct all along.
**Fixed**
- **Downloads from servers with custom dimensions opened as empty void.** Most creative-plot and
minigame networks run you outside the normal overworld, and those chunks landed in a folder the
saved world could never load. Your session's dimension is now always saved as the overworld.
- **You could open a download and be nowhere near it.** Minecraft hunts for a "safe" spawn near the
stored point and gives up over void, dumping you at 0,0. Saved worlds now put you exactly on your
download, flying.
- **WorldEdit rejected `.schem` files as corrupt.** One missing byte of header. The blocks inside
were always fine. Schematics now import cleanly into WorldEdit, FAWE and Litematica.
- **"Too big for schematic" on normal-sized selections.** The exporter is roughly 20x faster and the
limit now scales with your allocated RAM. A 333x163x315 area exports in under half a second.
**New**
- **Signs, banners, heads and beds survive a schematic export.** (Chests still come out empty:
servers never send container contents to your client.)
- **Sponge v3 schematics**, switchable in settings. Default stays v2 for the widest support.
- **Saves tell you what they captured**: where the world will open, and how many chunks were too far
away to save.
- Downloaded worlds freeze random ticks, so captured builds do not decay: no leaf decay, no melting
snow, no spreading grass.
**Changed**
- The HUD is now drawn by [kUI](https://modrinth.com/project/kui), so it matches your other KALPE
mods and can be moved in kUI's layout editor. kUI is optional: without it everything still works
and only the HUD is off.
**Install:** drop the jar matching your Minecraft version (`+mc1.21.8` or `+mc1.21.11`) plus Fabric
API into `.minecraft/mods/`. Add [kUI](https://modrinth.com/project/kui) 1.1.0+ if you want the HUD.
