This world contains all biomes in equal proportion, in an order that allows for the most natural climate transitions. Some really fun stuff happens when deep ocean biomes or cave biomes generate on the surface. The lush biome is especially gorgeous. There is also an ocean monument generating in an open cave, in its own bubble of water!

Using the teleporter at spawn, beam yourself up to Central Station, a light rail minecart network that connects points of interest. Along the way, you can view the gorgeous landscapes from above. [​Note: you may want to turn off biome blend, depending on your hardware.]

You can create a checkerboard world too! Import the settings below (as a .json file) at worldgen, or customize your settings using the World Settings Generator: https://misode.github.io/world/
