About this Mod
YUNG's Better Caves completely overhauls Minecraft's cave systems. Caves are small and unassuming at the surface, but the deeper you go, the crazier things get. You'll find lava caverns, underground lakes and rivers, flooded caverns, and more!
Better Caves is a powerful and customizable Minecraft cave mod, with dozens of options and support for dimension-specific configurability. For information on how to use the extensive configuration, see the wiki!
If you're looking for older versions of Better Caves (pre-1.20.1), check out the Forge and Fabric pages on CurseForge.
YUNG's Better Caves is intended to be fully compatible with as many worldgen mods as possible. The following are known compatibility issues:
- Set [threadedWorldGen].enabled to "false". Otherwise, you may have issues with pockets of lava spawning within water regions. Note that this applies to C2ME on 1.20.1 ONLY - it is not necessary to make this change on 1.21.1.
