Biome composition
Shares are measured across the built map, and "not found" means not in the built map. Past its edge the world keeps generating normal vanilla Minecraft chunks, so those biomes can still be found out there.

Shares are of the cave volume, from the underground scan. See Caves for the full breakdown.
Caves
What this world's caves are made of, by volume, measured from the save in 4 block cells.
Measured under the built map, and "not found" means not under it. Past its edge the world keeps generating normal vanilla Minecraft chunks, so vanilla cave biomes missing here can still be found out there.
- Deep Dark 0.3%
- Dripstone Caves 0.5%
- Ice Caves Missing
- Lush Caves 12.5%
- Magma Caves 1.4%
- Normal Caves 85.4%
- Sulfur Caves Missing
- Normal Caves 85.4%
- Lush Caves 12.5%

- Ice Caves Missing
- Sulfur Caves Missing
Inferred. These have no biome of their own in Minecraft, so they are named from the blocks around the cave rather than read from the save.
Structure coverage

Loot tables
Which of the game's loot tables can turn up on this map, read from the world's own files. Included means the scan found the table itself; missing means neither it nor the structure carrying it was found in the built map.
Counted inside the built map. Past its edge the world keeps generating normal vanilla Minecraft chunks, so tables not seen here can still turn up out there.

Questions about Advent Map 12
- What is Advent Map 12?
-
Advent Map 12 is a hand-made survival world of 3,072 × 3,072 blocks, made with WorldPainter, World Machine, Gaea, Axiom and WorldEdit, built for Minecraft Java 1.21.5. You download the world folder and play it like any other save, in singleplayer or on your own server.
- How big is Advent Map 12?
-
3,072 × 3,072 blocks, so about 9 million blocks of surface. Walking from one edge to the other takes roughly 12 minutes at normal walking speed. The terrain runs from Y -64 to Y 320.
Outside that area the world keeps generating normal vanilla Minecraft chunks, so you never hit a wall, you just leave the built part behind.
- Which Minecraft version does Advent Map 12 need?
-
Advent Map 12 is made for Minecraft Java 1.21.5 and opens in 1.19 and later. Between the two, anything added after the release you load it in is removed or replaced (new biomes load as plains), so 1.21.5 or newer shows the world as built. Releases older than 1.19 cannot open it.
Bedrock players need a converted copy. See the Bedrock notes in the FAQ.
- Which biomes are in Advent Map 12?
-
23 in total. The land is mostly Plains (28.2%), Stony Peaks (17.8%), Beach (10.6%) and Taiga (5.8%), counted as shares of the land rather than of the whole map.
Water covers 44.3% of the map, and land 55.1%.
By volume this world's caves are Normal Caves (85.4%), Lush Caves (12.5%) and Magma Caves (1.4%). The cave breakdown has the rest.
The full breakdown is further up this page, with every biome and its share.
- Which structures are in Advent Map 12?
-
10 of the 20 structure types the scan checks are confirmed present: surface (2/8), underground (4/6), ocean (2/4), portal structures (1/1) and settlements (1/1).
Not confirmed: Abandoned camps (missing), Desert pyramids (missing), Igloos (missing), Pillager outposts (not checked), Swamp huts (missing) and Woodland mansions (missing). "Missing" means the scan looked and it is not in the built map; "loot only" means its chests are here but the structure is not; "possible" means only indirect evidence was found.
The structure list above names every one of them.
- Is Advent Map 12 ready to play in survival?
-
Yes. A scan of the world file confirms loot tables, structures, animals and ores, so the survival loop runs from the first night: chests hold the game's real loot tables, mobs spawn as they do anywhere else, and you can mine, farm and build without adding anything. It plays in vanilla Minecraft, with no mods, no datapacks and no creative mode.
The world contents report at the bottom of this page holds the item-by-item detail.
- Where do I download Advent Map 12?
-
From the download link on Google Drive, also on the button at the top of this page.
Also available: the PlanetMinecraft project page, which carries the release notes and the known issues for this particular build.
- What is new in Advent Map 12?
-
Every world is built on the one before it, and Advent Map 12 brought 2 logged changes into the line: new terrain, new assets and fixes to the generators that made it.
From its list:
- new meadow / plains type updated
The full list is on this page. These are the world's own additions, not patches released after it, so an older download is not missing them.
- Can I look at Advent Map 12 before downloading it?
-
Yes. Open it in the 3D explorer and fly the real terrain in your browser, with the biomes, the caves and the marked structures. Nothing to install.
How do I install Advent Map 12 on Java Edition?
- Unpack the archive you downloaded from Google Drive.
- Open your saves folder. On Windows press
Win+Rand enter%appdata%\.minecraft\saves. On macOS it is~/Library/Application Support/minecraft/saves, on Linux~/.minecraft/saves. - Move the unpacked folder in. It must be the folder that contains
level.dat, not a folder wrapping it. - Restart Minecraft on 1.21.5 or newer and pick the world in singleplayer.
Can I play it on Bedrock, or on a server?
Bedrock needs a converted .mcworld copy, and converted worlds carry their own
quirks around spawn, chests and villagers.
For a server, drop the world folder in as the server's world and start it.
