by Apothicon

Stratospherical Expansion reshapes Overworld generation, with sky island terrain and custom biomes that replace the vanilla ones.

ForgeClient and serverMIT LicenseOpen source1.18.2 – 1.20.1

What it does

The mod rebuilds Overworld generation around floating sky islands and a set of custom biomes. Its vanilla biomes are reworked rather than kept as they are. TerraBlender is required, and the mod is published for Forge only, in three release versions covering 1.18.2 – 1.20.1, with 0.3.1 for 1.20.1 as the latest file.

Key features

  1. Sky island terrain

    Floating islands are generated across the Overworld in place of the usual continental layout.

  2. Custom biomes

    New biomes are added and shaped to suit the sky island terrain.

  3. Reworked vanilla biomes

    Existing vanilla biomes are redesigned with new features and terrain.
