Minecraft:Single Biome

A single biome world set to forest or wooded hills generates an endless forest, even in oceans, mountains, or caves.

Single biome is a Minecraft:world type or a vanilla Minecraft:world preset in which the entire Minecraft:Overworld consists of one Minecraft:biome. It is simple to customize, albeit very limited.

The customization screen for single biome

Single biome can be enabled in the Minecraft:Create New World screen, on the "World Type" button. This reveals a menu where the player can select any existing biome to generate in the Overworld.

Minecraft:Server operators can set a single biome world type by setting level-type=minecraft:single_biome_surface in Minecraft:server.properties. This also allows custom biomes from Minecraft:data packs.

Additionally, players can override any dimension with the same fixed biome source generation like single biome using a Minecraft:custom dimension data pack.

Bedrock Edition

Code for the single biome world type exists in Bedrock Edition; however, it is inaccessible through the game's GUI. It can only be accessed by editing the world's level.dat file using external programs.<ref>Generate custom flat and single biome worlds on Bedrock!</ref> This code supports every biome in the game, including unused biomes and custom biomes if available in the world's Minecraft:behavior packs.

Servers cannot create single biome worlds, but placing a single biome-enabled world in a server or Realm generates regular single biome world.

Generation

Different biomes are placed on the same terrain.

Single biome uses a single fixed biome source for generating the Minecraft:Overworld with the default noise generator. Similar to the default world type, this configuration generates a world with a bedrock floor at the Y=-64 lower height limit, and the rest of the terrain is generated on top of it. However, in contrast to the default world type, the Overworld in a single biome world consists of only one biome.

Template:IN, using a biome from the Nether or the End to generate the Overworld results in a world with their structures and characteristics, albeit very incomplete. For example, Minecraft:warped forest does not generate any warped trees, but still generates partial fog, particles, and Minecraft:Nether fortresses. This is caused by a bug where the biome surface and terrain is different from their own dimension.<ref>Template:Bug</ref>

Template:IN, biomes from different dimensions generate properly with all features, including the Minecraft:lava sea.

The Nether and the EndTemplate:Only are unchanged from their Default world type counterpart. Template:IN, the End generates the same End terrain but applies the selected biome and generated Minecraft:features on top of it, resulting in glitched terrain.
