About this Mod

Aetherial Islands: Clusters Edit

This is a simple data pack that modifies the terrain functions for the island placement in Aetherial Islands, Skylands Over The Sea, and Angel Islands to be in clusters, rather than uniformly distributed throughout the world.

Make sure this is above the other datapack when using, otherwise it will not work!!

Check the Gallery for instructions on modifying the cluster size and spread! You can also upload it to Misode and edit there.

If you are as annoyed with the Trial Chambers taking up the sky as I am, you can reduce them by modifying their structure_set.json file separation/spacing fields. I'll maybe add that in the future.
