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.

WorldPainter source files for Almorterra
Almorterra is published twice: the finished world you drop into your saves folder, and the project source files it was built from. Depending on the world that means the WorldPainter project, with the terrain, the biomes and the structures still on separate layers, or the black and white height and colour maps behind it, or both.
- Switch the structure layers off and export a clean terrain-only version.
- Re-export at a different Minecraft version instead of waiting for an updated build.
- Reshape the terrain, move a biome or fix something yourself, on the original layers.
- Use the terrain as the base for your own map, on your own server or project.
Opening them needs WorldPainter, which is free. See the FAQ for the terrain-only case in full.
These files are for you, not for passing on
The project source files are licensed to you personally, and they are the one part of a world that is not under Creative Commons. Everything above is yours to do. What is not:
- Share, pass on or publish the project source files
- Sell the source files, or sell a world exported from them
- Redistribute a world exported from them, modified or not

Questions about Almorterra
- What is Almorterra?
-
Almorterra is a hand-made survival world of 4,096 × 4,096 blocks, made with WorldPainter, World Machine, Gaea, Axiom and WorldEdit, built for Minecraft Java 1.18.1. You download the world folder and play it like any other save, in singleplayer or on your own server.
- How big is Almorterra?
-
4,096 × 4,096 blocks, so about 17 million blocks of surface. Walking from one edge to the other takes roughly 16 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 Almorterra need?
-
Almorterra is made for Minecraft Java 1.18.1 and opens in 1.18 and later. Between the two, anything added after the release you load it in is removed or replaced (new biomes load as plains), so 1.18.1 or newer shows the world as built. Releases older than 1.18 cannot open it.
Bedrock players need a converted copy. See the Bedrock notes in the FAQ.
- Which biomes are in Almorterra?
-
20 in total. The land is mostly Plains (41.7%), Windswept Hills (22.7%), Snowy Plains (11.2%) and Desert (9.4%), counted as shares of the land rather than of the whole map.
Water covers 59.5% of the map, and land 40.5%.
The full breakdown is further up this page, with every biome and its share.
- Which structures are in Almorterra?
-
7 of the 20 structure types the scan checks are confirmed present: surface (1/8), underground (4/6), ocean (1/4), portal structures (0/1) and settlements (1/1).
Not confirmed: Abandoned camps (missing), Desert pyramids (missing), Igloos (missing), Pillager outposts (not checked), Swamp huts (missing) and Trail ruins (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 Almorterra 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 Almorterra?
-
From the download link on Patreon, also on the button at the top of this page.
Also available: the source files on Patreon and the PlanetMinecraft project page, which carries the release notes and the known issues for this particular build.
- What is new in Almorterra?
-
Every world is built on the one before it, and Almorterra brought 8 logged changes into the line: new terrain, new assets and fixes to the generators that made it.
From its list:
- added desert oases (Gen1)
- added desert dynamic dunes
- improved ocean ice
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 Almorterra 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 Almorterra on Java Edition?
- Unpack the archive you downloaded from Patreon.
- 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 1.18.1 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.
What may I do with it?
