Formations Nether Mod (1.20.1) – New Structures for The Nether

The Nether has always felt a bit empty once you know your way around — Formations Nether Mod changes that by scattering dozens of handcrafted structures across every biome in the dimension. From eerie ritual altars and hidden houses tucked inside crimson forests to towering blackstone castles and mysterious shrines, every expedition into the Nether now comes with genuine surprises. Created by SuperMartijn642 and downloaded over 4.2 million times, this is one of the most popular Nether expansion mods available, and it pairs perfectly with the companion Formations Overworld Mod if you want the same treatment for the surface world.

Key Features

• New Nether Structures — Explore a Fossil Hut, Strange Altar, Shrine, and Black Stone Pedestal scattered throughout Nether biomes, each with unique loot and atmosphere.

FAQ

Does Formations Nether Mod work with existing Nether worlds?

The mod adds structures to newly generated chunks only. If you've already explored your Nether, you'll need to travel to unvisited areas or reset your Nether dimension to see the new structures.

Do I need both Formation Mod and Formations Nether Mod?

Yes. Formation Mod is a required base library that handles the structure generation system. Without it, Formations Nether will not function. Both files must be placed in your mods folder.

Can I use Formations Nether together with Formations Overworld?

Absolutely. Both mods are designed by the same author to work side by side. Formations Nether adds structures to the Nether while Formations Overworld focuses on the surface world, giving you new exploration content in both dimensions.
