Description
Summary:
JJThunder to the max is a 1:1 world generation that completely changes the way the terrain is generated.
It focuses on adding massive mountains that stretch to almost 2000 blocks tall, while still having flat plains at the bottom.
It also terraforms caves to match the theme of the world generation.
Data pack Version:
v0.3.0 is out for 1.21 and only available for now as data pack version.
Don't worry, we'll release the mod version sooner or later!

Notes:
Allocate more RAM. By default, its 2GB, so depending on your usage and render distance, you might need more.
Do not use in existing worlds, or it will corrupt your existing buillds.
Not compatible with terralith, tectonic, and other world generation data packs.
Semi-Compatible with biome mods like Biomes O Plenty, however, I wont call it compatible.
Requires beefy computers, or optimization mods like sodium, etc.
