Large Biomes is a world type that generates Overworld worlds at a higher scale than in normal worlds. It is intentionally programmed to not affect Nether biomes at all.[1]

Large Biome worlds are generated as Default worlds, but have 16 times as much area (multiplied by 4 along the X and Z axis), causing the biomes of the Overworld to be expansive. A Default and Large Biome world sharing the same seed are geographically the same, overall. Rivers are not larger than they are in a default world.

The player can use a map to gain a visual representation of the scale of the biomes in their world.

Large Biomes offer a play experience different from regular sized worlds. If a player starts in an undesirable area, such as a desert, it can be difficult to survive. The generation system also leads to rare biomes being far more difficult to come by, but with more valuable resources when they are eventually found.

  • The scale of biomes can be altered through the firstOctave parameters in biome_source of Custom worlds. Decreasing each firstOctave by 2, roughly makes biomes have a similar size to Large Biomes. [needs testing]
