Azure Seas Worldgen mod

by Digital Paradox

Azure Seas Worldgen replaces the terrain of a NeoForge 1.21.1 world with organic, tree-like formations built from 3D Voronoi noise.

NeoForgeServer-side onlyApache License 2.01.21.1

What it does

Generation uses 3D Voronoi noise to produce branching, web-like veins of stone, grass and other blocks that run through a layer of sand and water. The result looks organic, close to natural structures such as trees, rather than the usual terrain shapes. A single sand layer forms the floor of the world up to Y=63, and water fills the space above that layer.

The design keeps the world completable in normal survival mode. Resources needed for the endgame remain reachable, and nothing essential is permanently missing. The mod runs on the server only, so players join without installing it. It is released under the Apache License 2.0 and is not open source. Builds target 1.21.1 only, with 1.0.1 as the latest NeoForge file, published 2026-09-06.

The mod was developed specifically for the Azure Seas modpack, and no release date for a standalone version has been confirmed.

Key features

  1. Voronoi terrain shapes

    Three-dimensional Voronoi noise shapes the terrain into irregular, organic formations.

  2. Branching veins

    Veins of stone, grass and other common blocks wind through the sand and water layers.

  3. Sand and water base

    A single sand layer up to Y=63 with water above forms the lowest part of the world.

  4. Survival-safe generation

    Essential resources stay reachable, so a normal survival world can still be completed.
