This mod is a expansion to vanilla cave system that able to generate huge and connective caves comparable to modern minecraft.
These giant caves usually only generates in the lower layers of the world, so they do not break your landscape on the surface.
Fully compatible with BOP and Et Futurum Requiem.
This is a fork of greggen, with the removal of unnecessary GT6 dependency.
