Cascades

The datapack changes the terrain that the 1.18 generator produces. It draws on features of older Minecraft Beta releases, such as towering cliffs, floating islands and steep overhangs, and places them into the cascading landscape of the newer generator. The result is a rougher surface with more unpredictable cliffs, aimed at a split of about 55:45 between crazier and flatter terrain. Large-scale placement of mountains, rivers and oceans stays close to vanilla 1.18 and later, so familiar seed layouts still show their overall shape.

Land-to-water transitions are smoother, and sand and gravel beaches return. Rivers can run fully through the world, including underground, which makes travel by boat easier. The datapack adds no new structures and only a few changed biomes, with almost every vanilla biome kept. Server owners install it on the server, and players may add it too. Cascades Cool Biomes and Monolithic Modernity both require Cascades. Cascades is published for Fabric, Forge, NeoForge and Quilt across 27 release versions, 1.18.2 – 26.3, and the code is not open source, released under the Creative Commons Attribution Non Commercial No Derivatives 4.0 license.
