Caves not Cliffs mod
(1.17 backport to 1.12.2)
This mod is backport of 1.17 "Caves & Cliffs" update to version 1.12.2
Key features:
Lush caves (procedure generation):
Dripstone caves (procedure generation):
Amethyst geodes (structures):
Cauldron can store lava:
Cauldron can be filled by pointed dripstone:
This mod is an addon to other Caves and Cliffs mode, all new blocks in my mode are taken from there. Supermj767's mod add new blocks, but they won't spawn in your world in 1.12.2 version, also it does not implement filling cauldron with lava.
Since this mode don't change cave's shape generation, it's also highly recommended to try together with YUNG's Better Caves mode for better 1.17 experience.
