Islands Overworld is a worldgen datapack that changes the generation of the vanilla world to flying islands.

If you prefer to add a new dimension instead of replacing the overworld, look at Islands Overworld Dimension.

Installation

  • Double check the compatibility between Minecraft's version and datapack's version (worldgen can mess up real quick).
  • Create a new world and drag the datapack upon world’s creation.
  • Make sure the spawn is correct.

Islands intensities (Patreon feature)

You can chose islands intensity between 5 values: tiny, small, medium, large and massive.
A different datapack can be downloaded for each intensity.

Is it compatible with mods adding new structures (like Valhesia) or new biomes (like Biome You'll Go) ? Will they generate in/as skylands ?

No idea :/ Might be, as it overrides the noise_settings, and not the dimension itself.
