What it does

The data pack changes how the world generates: caves reach 128 blocks further down, cliffs stand taller, and mountains rise higher and steeper, while the world build limit is raised to 1024. Rivers, oceans and dry rivers are deeper and wider, with floors of mud, clay, gravel and packed mud. Geodes appear slightly more often, and diamonds are more common in jungles. Oasis deserts are generated as well. Only the server has to run it, while players may leave it out.

Key features

Deeper caves and taller cliffs
Caves generate 128 blocks lower, and cliffs rise higher, so vertical exploration covers more of the map.
Reshaped mountains and rivers
Mountains are taller and steeper, while rivers and oceans are deeper and wider with mud, clay and gravel floors.
Extended world height
The world build limit is raised to 1024, with an obsidian wall at y=0 marking the bottom of the generated area.
