The official worldgen mod for Exosphere 2 and Exosphere 2 + Create! Now as a standalone mod.

Exosphere Worldgen adds sky island overworld generation and tweaks further vanilla features to create a unique experience. Inspired by Apothicon’s "Stratospherical Expansion," it recreates that distinctive world shape and modifies foliage decoration, structure placement, ore generation, and loot tables to refine your survival playthrough on sky islands.

Each part of the world looks like the perfect place for your next base.

Are you in need of prismarine, corals, or other ocean-related items and blocks? Explore the river biome mud ponds for kelp, sea pickles, and shipwrecks with a customized loot table containing all ocean-related loot. Even aspects like fishing have been tweaked to no longer require large open water bodies in a world without oceans.

Incompatibilites

Lithostitched, probably due to my datapack using NeoForge’s native biome modifiers, causing odd stuff
Other mods/datapacks that modify vanilla biomes and or features, sometimes a mod like Feature Recycler might help

Usage and distribution

Feel free to use the mod in your own modpacks using CurseForges default distribution

To get the full Exopshere worldgen experience I suggest my other new datapack adding the ore geodes: BM: More Geodes
