Subsurface

by EMD123

Subsurface, a world generation mod, adds eleven new cave biomes that generate in the overworld and the nether.

FabricForgeNeoForgeQuiltServer required, client optionalApache License 2.0Open source1.20 – 26.2

What it does

Eleven cave biomes are added underground and in the nether, and they generate inside existing vanilla cave biomes so the two blend into hybrid caves. The biomes coexist with other datapacks and mods, which keeps the change to cave generation rather than to the rest of the world.

Key features

  1. Eleven cave biomes

    Eleven new underground biomes are added across the overworld and the nether, each with its own cave layout.

  2. Hybrid caves

    New biomes generate inside vanilla cave biomes, so a single cave can mix vanilla and Subsurface terrain.

  3. Compatible biome layout

    The biomes sit alongside other datapacks and mods that change caves or biomes without conflicting with them.

Questions

Does Subsurface need a loader-specific API?

Subsurface is published for Fabric, Forge, NeoForge and Quilt, and the latest file for each loader is 1.0.5+mod for 26.2.

Does Subsurface have to be installed on the client?

No. The server must run it, but players may leave it out, so a player who does not install it can still join.
