Questions about McMeddons Advent Map 21
- What is McMeddons Advent Map 21?
-
McMeddons Advent Map 21 is a hand-made survival world of 2,048 × 2,048 blocks, made with WorldPainter, World Machine, Gaea, Axiom and WorldEdit, built for Minecraft Java 1.20.2. You download the world folder and play it like any other save, in singleplayer or on your own server.
- How big is McMeddons Advent Map 21?
-
2,048 × 2,048 blocks, so about 4 million blocks of surface. Walking from one edge to the other takes roughly 8 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 McMeddons Advent Map 21 need?
-
McMeddons Advent Map 21 is built for Minecraft Java 1.20.2. 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 McMeddons Advent Map 21?
-
19 in total. The land is mostly Plains (43.2%), Beach (22.2%), Jagged Peaks (9.4%) and Meadow (7.5%), counted as shares of the land rather than of the whole map.
Water covers 47.0% of the map, and land 52.8%.
The full breakdown is further up this page, with every biome and its share.
- Which structures are in McMeddons Advent Map 21?
-
5 of the 19 structure types the scan checks are confirmed present: surface (1/7), underground (2/6), ocean (1/4), portal structures (1/1) 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 McMeddons Advent Map 21 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.
- Can I look at McMeddons Advent Map 21 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 McMeddons Advent Map 21 on Java Edition?
- Unpack the archive you downloaded.
- 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 1.20.2 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?
