Confluence
by ReiMeyer
Confluence is a Fabric terrain mod that reshapes the overworld with rivers, mountains, lakes and 23 new biomes for fantasy-styled landscapes.
What it does
Rivers are generated from the way water flows across the world, and lakes form where a river settles, so the water layout follows the terrain rather than being placed at random. Rivers use Minecraft's own water states, which gives them visible flow, and waterfalls are part of the shaping. Mountains are reworked to look more natural. Confluence also adds 23 new biomes to the overworld.
The mod is set up as a custom world preset: a player creates a new world and selects the Confluence world type, and the terrain is then generated with that preset. Confluence runs on the client and on the server, so the server and every player need it. Builds exist for Fabric only, across 11 release versions 1.21.1 – 1.21.11, and the latest file, 0.4.0 for 1.21.11, was published on 2026-08-15 on the alpha channel. The mod is released under All rights reserved.
The developer aims for terrain that is realistic and attractive while keeping generation times short and frame rates steady. Work listed for later versions includes more fantasy elements, deeper features and bug fixes in the terrain generator.
Key features
Flowing rivers
Rivers are routed by how water moves across the terrain and use Minecraft's water states for their visuals.
Lakes from river flow
Lakes are created where a river's path ends up, based entirely on the flow computed during world creation.
Realistic mountains
Mountain ranges are reshaped to look more natural, with a fantasy-leaning style layered on top.
23 new biomes
The overworld gains 23 additional biomes that appear alongside the vanilla ones in generated worlds.
