About this project
What does Better Underground Caves add?
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.
