Stratospherical Expansion NeoForge

by Kamilchik

Stratospherical Expansion reshapes the Overworld into a sky realm of floating landmasses, cliffs and island chains, replacing the familiar flat terrain for new worlds.

What it does

Terrain generation is the core of the mod. Floating landmasses, cliffs, gaps and vertical landforms replace the flat Overworld surface, while vanilla biomes stay recognizable through their height, shape and atmosphere. Custom biomes and custom worldgen features add trees, vegetation, rocks and other biome decoration to the new terrain.

The mod changes Overworld generation heavily, so it conflicts with other mods that replace Overworld noise settings, biome definitions or placed features. It uses TerraBlender for biome integration, which must be installed alongside it. Only newly generated chunks follow the modded generation, so the clean experience is a fresh world, and client and server must run the same mod list. The mod is released under the MIT License, and its source code is public. It was built for Minecraft 1.21.1 on NeoForge and has files for 1.21.1 and 26.1, with 0.4.6 as the latest NeoForge file for 1.21.1.

Key features

  1. Sky continents

    Broad floating landmasses and sky continents take the place of the flat Overworld surface.

  2. Island chains and cliffs

    Smaller islands, broken edges, valleys and hanging stone give exploration a vertical, uneven character.

  3. Custom biomes

    Custom biomes are added to the Overworld, with decoration such as tall forests and colorful biome-driven details.

  4. Recognizable vanilla biomes

    Existing vanilla biomes keep their identity while gaining new height, shape and atmosphere.
