Naturallith

by viralhysteria

Naturallith places Naturalist mobs inside Terralith biomes by adjusting their spawn weighting, so wildlife appears across custom terrain.

What it does

Naturallith is a compatibility extension for Naturalist mobs and Terralith biomes. Naturalist creatures are redistributed across Terralith terrain, and vanilla spawn tables that would otherwise dominate those biomes are reduced where needed. The result is that grasslands, forests, wetlands and mountains receive fauna suited to their climate and terrain profile.

Client and server both need the mod, so the server and every player run it. Naturallith requires NeoForge and is released for 1.21.1 only, with the latest file at 1.0.3, published 2026-06-22. It is licensed under the GNU General Public License v3.0 or later and is not open source. Naturalist and Terralith are the two mods it connects, and vanilla mobs continue to spawn as before where no change is needed.

Key features

  1. Naturalist spawns in Terralith

    Naturalist mobs can spawn inside Terralith biomes that lack proper coverage in the default setup.

  2. Biome-aware spawn weighting

    Spawn weights follow the ecosystem type of each biome, so fauna matches the surrounding environment.

  3. Reduced vanilla competition

    Vanilla spawn entries are lowered only where they crowd out the new creatures.

  4. Fewer low-priority ambient mobs

    Minor ambient mobs are kept from appearing in overrepresented numbers across custom terrain.

Questions

Does Naturallith need Naturalist and Terralith?

Yes. The mod is a compatibility extension, so the Naturalist mob pack and the Terralith biome pack must both be installed alongside it.

Can Naturallith run on a single-player world without a server?

Yes. Client and server means the mod is installed on the client for single-player play, and on the server for multiplayer.

Which game version does Naturallith support?

Naturallith is built for 1.21.1 only, on NeoForge, and its latest file is 1.0.3 for that version.
