Details
Islands Overworld is a worldgen datapack that adds a new dimension based on a vanilla worldgen but with flying 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 Islands Overworld.
Installation
- Play Minecraft 1.20 or more recent.
- Make sure to download the exact corresponding datapacks's version (worldgen can mess up real quick)
- Create a new world and drag the datapack upon world’s creation.
- Grab an elytra and some fire rockets, then fly through the sky.
Traveling
- Fly high in the sky to reach the flying islands dimension
- Descend in altitude in the flying islands to return to the overworld
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.
