What it does

Underground biomes are added to a world through this library, which gives other mods a common way to place cave biomes beneath the surface. Its generation approach draws on the layout of the SimpleCaveBiomes mod by Lymia, and the author states that it was rebuilt on a new system.

Required dependencies are Fabric API and Platform. The library runs on client and server, so both the server and every player need it, and it is released under the GNU Lesser General Public License v3.0 only. The code is open source, and public links to the source, issue tracker and wiki are available. Builds exist for 1.16.5 only, with 2.0.0 as the latest file for both Fabric and Forge, dated 2025-01-09.
