Terralith is a Minecraft data pack that rebuilds Overworld generation with over 95 new biomes and reworks almost every vanilla biome, using only vanilla blocks. The newest data pack release is 2.6.5+26.3 (2026-09-27), covering 1.19 to 26.3 with no dependencies. The same project also ships as a mod for Fabric, Forge, NeoForge and Quilt.
What changes in-game
Realistic biomes include Yellowstone, Yosemite Cliffs, Shield and Desert Oases. Fantasy biomes include Moonlight Grove, Amethyst Rainforest, Scarlet Mountains, Mirage Isles and the Alpha Islands. New terrain types add canyons, shattered biomes, floating islands and deep ocean trenches. Underground, custom caves include the Underground Jungle, Infested and Fungal Caves, and the dangerous Frostfire Caves.
Structures tie the terrain together: the tall Spire in icy biomes, rare Fortified Villages in plains and desert, and the Glacial Hut. Official add-ons can remove the intro message, disable structures, add stone recipes or restore vanilla granite, andesite and diorite blobs. Data pack add-ons must load above Terralith.
How to install Terralith
- 1.Get the data pack .zip from Modrinth.
- 2.Single-player: add it from the Data Packs button when creating a world, or place it in saves/<world>/datapacks.
- 3.Dedicated server: place the .zip in the server world's datapacks folder.
- 4.Run /reload or restart. Terralith terrain only appears in newly generated chunks.
For general steps and troubleshooting, see how to install data packs. Mod users put the .jar in the mods folder with the matching loader. The newest Fabric and NeoForge releases require Lithostitched. Fabric 1.21.1 also needs Fabric API, and the 1.18.2 Fabric, Forge and Quilt files need Cristel Lib. The mod is required on the server and optional on the client.
Known issues and conflicts
- Since 2.6.0 the mod and the data pack differ, and swapping between them can damage a world.
- Forge and Quilt releases end at 2.5.14 (2025-12-16) for 1.21.11, so 26.x needs the data pack, Fabric or NeoForge.
- Biome mods work when they use TerraBlender or equivalent, but biome-adding data packs are typically incompatible.
- The mod pairs with Tectonic. With the data pack, use Terratonic instead.
Questions about Terralith.
4 questions
How do I install Terralith?
Put the data pack .zip in saves/<world>/datapacks, or add it from the Data Packs button when creating a world. On a server, use the server world's datapacks folder. Run /reload or restart. Only newly generated chunks use Terralith terrain, so start a new world.
Does Terralith work on multiplayer?
Yes. On a server, the data pack goes in the server world's datapacks folder. The mod form is required on the server and optional on the client. Choose one form per world, because since 2.6.0 the mod and data pack differ and swapping between them can damage a world.
Which Minecraft versions does Terralith support?
The data pack covers 1.19 to 26.3, with 2.6.5+26.3 as the newest release. Fabric covers 1.18.2 to 26.3 and NeoForge 1.20 to 26.3. Forge and Quilt releases run from 1.18.2 to 1.21.11 and end at 2.5.14.
Can I remove Terralith from a world later?
No. Terralith cannot be removed from an existing world. Adding it to an old world is also not recommended, so reset the world first or start a new one. Data pack worldgen only affects newly generated chunks, which is another reason to begin fresh.
