Description

The official Datapack for BM: Exosphere 2!
Exosphere Worldgen is a standalone datapack that brings sky-island world generation and fully customized overworld features to modern Minecraft versions. Built as an evolution of the original mod "Stratospherical Expansion" by Apothicon, it preserves the stunning visuals, lush foliage, and signature atmosphere of its predecessor while pushing the concept with new elements even further.
This version introduces a variety of enhancements, including per biome sky-island ceilings (cave vines and leaf/block columns), improved vegetation, and numerous gameplay-beneficial tweaks designed to make this unique world type more immersive and enjoyable.
Currently requires Neoforge modloader for the foliage decorators.

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