Caves and Canyons Mod Guide

What the Mod Changes

Caves and Canyons Mod reworks how underground terrain generates, focusing on two things: canyons and caves.

Traditional canyons are replaced by rift valleys. Instead of small gaps in the surface, these are vast, immersive canyons that reach all the way down to y:-20. Because they cut so deep, they double as a fast route between underground levels — you can descend through a rift rather than mining a staircase. They are rare, so finding one is a notable event rather than a routine sight.

Cave entrances are also adjusted. On the surface they appear narrower, which keeps the landscape above ground more intact and reduces the disruption caused by open holes. Below that, the cave systems open up: large, expansive caverns are pushed into deeper underground layers, so the rewarding exploration happens further down.

In short, the mod trades surface clutter for deeper, more dramatic underground terrain.
