Java mod listed for Minecraft 1.19–1.21. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
This is an independent data pack for epic underground cave terrain, optimizing the original cave terrain and adding large underground cave features.
💡Features:
- Better caves, where there will be more flat ground, reducing vertical drop caves (the aim is to descend layer by layer like in a dungeon).
- Reduce the generation of large caves in low elevation and flat terrain, mainly generating on mountains.
- Add randomly generated underground caverns below y0 and generate magma rivers.
