Profundis: Nine New Quality Cave Biomes
by firenh
Profundis adds nine new cave biomes to the underground of Fabric and Quilt worlds, so caves differ from one another more than they do in vanilla.
What it does
The biomes generate underground and use vanilla-styled terrain. Mushroom Caves appear beneath humid biomes with mycelium patches, small red and brown mushrooms, huge mushrooms and shelf growths that sometimes glow. The caves with amethyst sit under hillier land and hold amethyst veins, calcite and smooth basalt in their walls. Black Caves use Tuff, Deepslate and Blackstone walls and can generate in almost any environment.
The mod runs on the server alone, so players join without installing it. Single-player worlds can also run it on the client. Profundis requires Fabric API on Fabric and Quilted Fabric API or Quilt Standard Libraries on Quilt; both are optional dependencies that the mod uses. Files cover game versions 1.18.1 – 1.21.4 across 13 releases, and the code is open source under the GNU Lesser General Public License v3.0 only.
