Description
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.
