Terralith Islands worldgen is an addon for Terralith, which add a dimension with Terralith floating islands. Travel between dimension by flying in the sky (require elytra, or any flying engine).

If you prefer to directly modify the overworld, instead of adding a dimension, look at Terralith Islands.

Installation

  • Download this datapack
  • Download the official Terralith.
  • Create a new world and drag the datapacks upon world’s creation.
  • Put the Terralith Islands on top (above Terralith).
  • Make sure the spawn is correct, or replace it with /setworldspawn and /spawnpoint .

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.
