Cave Tweaks

by Stardust Labs

Cave Tweaks changes how caves are generated in 1.18 and 1.18.1 worlds, with settings for almost every part of cave generation.

FabricForgeServer-side onlyCustom license1.18 – 1.18.1

What it does

The mod extends the cave overhaul that Minecraft added in 1.18. Cave biomes, underground biomes that are truly three-dimensional, and dripstone caves that can sit below lush caves, which vanilla never produces, are part of the set. Cave entrances can be rounded and layered, aquifers take much larger and more varied shapes, and partially flooded caves appear more often. Spaghetti tunnels are kept closed near the surface so they do not break the terrain, and pillars inside cave entrances are much less common to reduce clutter. Rare huge caverns and flat caverns that run across an entire map can also be generated, and spaghetti caves can be made thicker to form intricate systems.

The advanced configuration lets server owners edit almost every aspect of cave generation, including cave sizes, how often cave lakes form, and how often lush caves appear. With the default configuration the mod already changes caves, so no setup is required for a first run. The mod is published for Fabric and Forge, covering 1.18 and 1.18.1, and it runs on the server alone. The license is a custom one, so the code is not open source.

    Adds cave biomes and underground biomes whose shapes are three-dimensional, with dripstone caves below lush caves.
