JJThunder To The Max Data Pack introduces a whole new world generation experience based on JJThunder King of the Hills. It adds mountains that are 1800 blocks tall as well as flat plains, deep oceans, and smooth transitions.
This data pack also introduces new noise caves that replaces old ones. They start out small and claustrophobic, while growing with depth to reach a whole new world generation (The Underlands). Only the Underlands are endless while the other types of caves are not. Enjoy playing this data pack!
