Caves Revamp: Underground biomes
by myxazaur
Caves Revamp: Underground biomes gives underground areas new Desert, Frozen and Jungle cave types with their own terrain, mobs and loot rooms.
What it does
Caves Revamp adds three underground biome types. Desert Caves hold sand, sandstone and quicksand that can trap a player who walks into it. Deeper in these caves, concealed rooms hold loot for players who search for them. Jungle Caves are thick with grass, hanging roots and glowing plants that give light.
The biomes use a custom noise generation, so their shape and structure differ from vanilla caves. The mod also adds new mobs. It supports ColoredLux for some of its blocks. Caves Revamp Compatibility List is the page the author points to for add-on support. Forge is the only loader, and the mod is released under the MIT License. It is not open source. Files exist for 1.12.2 only, and the latest Forge file, 0.3.1.1, is on the beta channel.
