WorldPainter source files for Jaratorm
Jaratorm 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 Jaratorm
- What is Jaratorm?
-
Jaratorm is a hand-made survival world of 4,608 × 4,608 blocks, made with WorldPainter, World Machine, Gaea, Axiom and WorldEdit, built for Minecraft Java 1.17.1. You download the world folder and play it like any other save, in singleplayer or on your own server.
- How big is Jaratorm?
-
4,608 × 4,608 blocks, so about 21 million blocks of surface. Walking from one edge to the other takes roughly 18 minutes at normal walking speed. The terrain runs from Y 0 to Y 255.
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 Jaratorm need?
-
Jaratorm is built for Minecraft Java 1.17.1. Newer releases normally open it fine. Opening it in an older release is not supported: blocks and structures added after that version cannot load, and the world can be damaged by the attempt.
Bedrock players need a converted copy. See the Bedrock notes in the FAQ.
- Which biomes are in Jaratorm?
-
14 in total. The land is mostly Plains (60.8%), Snowy Plains (14.4%), Forest (8.0%) and Savanna (5.5%), counted as shares of the land rather than of the whole map.
Water covers 32.5% of the map, and land 67.5%.
By volume this world's caves are Normal Caves (98.6%), Magma Caves (1.0%) and Ice Caves (0.4%). The cave breakdown has the rest.
The full breakdown is further up this page, with every biome and its share.
- Which structures are in Jaratorm?
-
4 of the 16 structure types the scan checks are confirmed present: surface (0/6), ocean (0/4), underground (4/4), portal structures (0/1) and settlements (0/1).
Not confirmed: Desert pyramids (not checked), Igloos (not checked), Jungle pyramids (not checked), Pillager outposts (not checked), Swamp huts (not checked) and Woodland mansions (not checked). "Searched, not found" means the scan looked and came up empty; "not checked" means it has not been looked for yet.
The structure list above names every one of them.
- Is Jaratorm 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 Jaratorm?
-
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.
- Can I look at Jaratorm 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 Jaratorm 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 1.17.1 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.
