Better Single Biome
by e3l3rno
Better Single Biome changes how the single biome world type generates terrain, lowering the sea level and geode level and adding underwater vegetation.
What it does
The mod improves the Single Biome world mode. It lowers the sea level and the geode level, adds vegetation under water, and lets several generated structures spawn in more biomes than they normally would. A bundled datapack carries the same changes for players who prefer a datapack over a mod.
Most biomes are supported, with the mangrove swamp and the water biomes left out. The mod is published for Fabric, Forge and NeoForge for 1.21 – 1.21.4, and the server needs it while players may add it. The code is open source under the GNU Affero General Public License v3.0 only, and the source and issue tracker are public.
Key features
Lower sea level
The sea level in single biome worlds is set lower than in a standard world, leaving more land above the water.
Lower geode level
Geodes generate at a lower depth in single biome worlds than they normally would.
Underwater vegetation
Plants are placed under the water surface, so the seafloor is not bare in a single biome world.
More structure biomes
Several generated structures can spawn in additional biomes, so single biome worlds contain more of them.

Use cases
Single biome survival
Players who start a world limited to one biome get a terrain that places geodes, plants and structures differently from the vanilla settings.
Datapack-only servers
Server owners who cannot add a Java mod can use the bundled datapack to get the same single biome changes.
Who it’s for: Players and server owners who run the single biome world type and want its terrain and structure placement adjusted.
How it compares
Calamity Biomes adds new biomes and is published for Fabric, Forge, NeoForge and Quilt for 1.21 – 1.21.4, with the server needing it and clients optional, under All rights reserved, so its code is not open source. Water World is published for 1.20 – 1.21.4 on the same four loaders, also server required and client optional, and it is open source under the MIT License. Better Single Biome covers only Fabric, Forge and NeoForge.
