Updates to my projects continue on CurseForge as usual, I just dont like Modrinth
Exosphere Worldgen adds sky island overworld generation and tweaks further vanilla features to create a unique but balanced experience. Inspired by Apothicon’s "Stratospherical Expansion," it recreates that distinctive world noise and modifies foliage decoration, structure placement, ore generation, and loot tables to refine your survival playthrough on sky islands.
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.
To get the full Exopshere worldgen experience I suggest my other new datapack adding the ore geodes: BM: More Geodes

Unique sky island world generation, now on 1.21+!
