Speleogenesis Overhaul
Speleogenesis Overhaul completely reimagines the Overworld generation for Fabric (Minecraft 1.20.1). Instead of the fragmented vanilla caves, it introduces a single, fully interconnected subterranean world spanning an expanded vertical range from Y -512 to 511.
⛰️ Key Features
- Voronoi Highway Network: Cave systems follow the edges of a Voronoi diagram, ensuring complete connectivity by design.
- Mega-Caverns: Explorable massive spaces including spherical chambers (60–200 blocks wide) with flat floors for building, and long elongated galleries.
- Coastal Inlets: Tidal grottos along ocean coasts that allow players to sail or dive directly into the deep cave network from the surface.
- Vertical Rifts: Narrow, sheer canyons stretching hundreds of blocks vertically, seamlessly stitching underground layers together.
- Vanilla Integration: Retains vanilla block placement, biomes, and aquifers, optimized for performance and density.
