Moog's Nether Structures Guide: Every Structure, Location & Loot Table
Moog's Nether Structures fills the Nether with over 25 new structures built entirely from vanilla blocks and populated with vanilla mobs. From crumbling Blackstone ruins and Nether Brick circles to fully furnished houses with top-tier loot, this mod makes every Nether expedition feel fresh and rewarding.
Overview
Moog's Nether Structures is a worldgen mod that scatters over 25 new structures across every Nether biome. Unlike many structure mods, it doesn't add any custom blocks, items, or mobs. Every structure is built from vanilla materials and populated with vanilla entities, which means it blends seamlessly into your world and works alongside virtually any other mod without conflicts.
The structures range from tiny Blackstone rubble piles you might walk past without noticing, to fully enclosed houses stocked with chests of Diamond gear and Netherite materials. Certain structures are biome-specific, so exploring different parts of the Nether rewards you with genuinely different discoveries. If you've ever felt that the Nether was too empty between Fortresses and Bastion Remnants, this mod fills that gap perfectly.
Getting Started
- 1
Enter the Nether and start exploring
There is nothing to craft or configure. Simply install the mod and enter the Nether. Structures generate automatically in newly loaded chunks. If you already have a well-explored Nether, you'll need to travel to unexplored areas to find the new structures.
- 2
Look for small ruins first
The most common structures are Very Small Blackstone and Very Small Nether Brick ruins. These appear frequently across all Nether biomes and serve as landmarks that tell you the mod is working. They're small rubble piles and broken walls, easy to spot against the Netherrack terrain.
- 3
Visit a Crimson Forest or Warped Forest
These biomes contain exclusive structures you won't find elsewhere: Crimson Wells and Warped Wells (multi-level well structures), oversized Crimson and Warped Fungi, and Warped Pools. The Wells and Pools use jigsaw pieces to create multi-part structures that feel like natural extensions of the biome.

Search for houses to find the best loot
The Medium Houses are the primary loot structures. They spawn across all Nether biomes and contain chests with Diamond Pickaxes, Ancient Debris, Netherite Scrap, Gold Blocks, Golden Apples, and even Smithing Templates. These are the structures worth seeking out if you need Netherite materials.

Explore the Soul Sand Valley for unique structures
The Soul Sand Valley biome has two exclusive structures: the Graveyard and the Blackstone Circle. The Graveyard generates on the highest terrain in the biome and provides an eerie landmark. The Circle Blackstone is a ring-shaped ruin unique to this biome.
Ruins
Ruins are the most common structures added by this mod and come in two material variants: Blackstone and Nether Brick. They range in size from tiny rubble piles to imposing walls and pillar formations. None of the ruins contain loot chests; their purpose is to make the Nether feel like it has history and atmosphere.
Blackstone Ruins
There are four variants of Very Small Blackstone ruins, each a slightly different arrangement of crumbling Blackstone blocks. These generate frequently across all Nether biomes with a spacing of 20-24 chunks between placements. You'll also find a Medium Blackstone ruin (spacing 30, separation 18) and two large variants: Large Blackstone Pillars, which are tall column formations, and Large Blackstone Walls, which resemble broken fortification segments. Both large variants have a spacing of 36 chunks with a separation of 22.
Nether Brick Ruins
Similarly, three variants of Very Small Nether Brick ruins scatter across all Nether biomes. A Small Nether Brick ruin fills the mid-size gap, and a Large Nether Brick ruin (spacing 36, separation 22) provides a substantial ruined structure. The Circle Nether Brick is a distinctive ring-shaped ruin found in all Nether biomes with a spacing of 32 chunks.
Most ruins spawn in all Nether biomes, but the Circle Blackstone is exclusive to the Soul Sand Valley. If you're looking for variety, visit different biomes. Crimson Forests and Warped Forests each have their own unique wells, fungi, and pools that won't appear anywhere else.
Houses
The mod adds two Medium House variants that generate across all Nether biomes. These are the most valuable structures in the mod because they contain loot chests. Built from Nether materials, they look like abandoned shelters left behind by some unknown Nether inhabitant. Both variants generate on low terrain using the mod's custom placement system, which finds the lowest valid surface to place the structure on.
Medium Houses have a spacing of 32 chunks and a separation of 20, making them less common than small ruins but frequent enough that you'll encounter several during a dedicated Nether exploration session. Each house contains a chest using the "houses" loot table, which is one of the most rewarding in the mod.
House Chest Loot (Primary Roll)
| Diamond Pickaxe (enchanted) | Weight 12 |
| Diamond Shovel (enchanted) | Weight 15 |
| Ancient Debris (x1) | Weight 12 |
| Ancient Debris (x2) | Weight 5 |
| Netherite Scrap | Weight 8 |
| Gold Blocks (2-4) | Weight 16 |
| Golden Carrots (8-17) | Weight 10 |
| Golden Apple | Weight 10 |
| Saddle | Weight 12 |
House chests have a small chance to contain a Snout Armor Trim Smithing Template (1 in 12 chance) and a Netherite Upgrade Smithing Template (1 in 10 chance). These are separate rolls from the main loot, so you could find both in a single chest. The Netherite Upgrade Template alone makes these houses worth searching for.
Special Structures
Smoking Shrine
The Smoking Shrine generates in all Nether biomes with a relatively close spacing of 26 chunks and a separation of 17, making it one of the more commonly encountered special structures. It places on the highest terrain in its area and features a distinctive smoking or smoldering design built from vanilla blocks.
Graveyard
Exclusive to the Soul Sand Valley, the Graveyard is one of the mod's most atmospheric structures. It spawns on the highest terrain with a spacing of 36 chunks and separation of 22. Given the Soul Sand Valley's already eerie ambience with Ghasts, Skeletons, and Soul Fire, stumbling upon a Graveyard adds a perfect layer of environmental storytelling.
Lava Pool
The Lava Pool is a multi-piece jigsaw structure that generates in all Nether biomes. It uses a two-part template with upper and lower sections, creating a more complex formation than a simple lava lake. With a spacing of 41 chunks and separation of 26, these are among the rarer structures. They spawn on the lowest terrain in their area.
Biome-Exclusive Structures
Crimson Forest
The Crimson Forest receives two exclusive structure types. Medium Crimson Wells are multi-part jigsaw structures with upper and lower well sections, creating deep well formations made from Crimson materials. Two size variants exist, each with a spacing of around 36-40 chunks. Medium Crimson Fungi are oversized fungus formations, larger than anything vanilla generates, appearing in two variants to add visual diversity to the biome.
Warped Forest
The Warped Forest mirrors the Crimson Forest's exclusive structures with its own variants. Medium Warped Wells function identically to their Crimson counterparts but use Warped materials. Medium Warped Fungi create oversized fungal formations. The Warped Forest also gets a unique Warped Pool structure, a multi-piece formation with upper and lower sections that doesn't appear in any other biome.
Structure Spawn Rates (Chunk Spacing)
| Very Small Ruins | Medium/Large Ruins | Houses | Smoking Shrine | Wells/Pools | |
|---|---|---|---|---|---|
| Spacing | 20-24 | 30-36 | 32 | 26 | 36-41 |
| Separation | 11-15 | 18-22 | 20 | 17 | 22-26 |
| Biomes | All Nether | All Nether | All Nether | All Nether | Biome-Specific |
| Loot | None | None | Houses Table | None | None |
| Frequency | Very Common | Uncommon | Uncommon | Common | Rare |
Loot Tables
The mod defines three loot tables: Houses, Uncommon, and Treasure. The Houses table is used by the Medium House structures and offers a solid mix of Diamond tools, Netherite materials, and Gold. The loot quality sits between a Bastion Remnant's generic chests and its treasure room.
Treasure Loot Table
The Treasure table is the mod's best loot pool. It rolls 3 times from a table that includes Netherite Ingots (weight 15), Ancient Debris, Netherite Scrap, enchanted Diamond armor and weapons (80-100% durability), unenchanted Diamond gear, loose Diamonds (2-6), and a rare Enchanted Golden Apple (weight 2). The secondary pool adds Gold Blocks (2-5), Iron Blocks (2-5), Quartz (8-23), Gilded Blackstone (5-15), and other materials. Every Treasure chest also guarantees a Netherite Upgrade Smithing Template.
Uncommon Loot Table
The Uncommon table is a mid-tier loot pool featuring an enchanted Diamond Pickaxe, Diamond Shovel, enchanted Crossbow, Ancient Debris, Netherite Scrap, Spectral Arrows (10-22), a Piglin Banner Pattern, Golden Carrots, Golden Apples, and Soul Speed enchanted books. A secondary roll can yield Gold and Iron equipment, Crossbows, and Golden armor pieces. The Snout Armor Trim has a 1 in 21 chance and the Netherite Upgrade Template has a 1 in 19 chance to appear.
Opening chests near Piglins will aggro them, just like with any vanilla structure chest. If you're looting a house in a Crimson Forest or Nether Wastes where Piglins roam, wear at least one piece of Gold Armor to prevent them from attacking on sight, and be ready for a fight when you open the chest.
Technical Details
The mod uses a custom jigsaw structure system with two placement modes. Structures configured with "HIGHEST_LAND" search direction (like the Graveyard and Smoking Shrine) place on the highest solid surface in their area, making them visible from a distance. Structures using "LOWEST_LAND" (like Houses and Lava Pools) tuck into lower terrain, which can make them harder to spot but feels more natural.
All structures use the "beard_thin" terrain adaptation, which smoothly blends the structure into surrounding terrain rather than carving out a flat platform. The mod also performs terrain height checks (with a configurable allowed range of 3 blocks) to avoid placing structures on extreme terrain slopes. The "cannot_spawn_in_liquid" flag on every structure prevents them from generating inside Lava lakes.
The mod includes optional support for the Biomes You'll Go (BYG) mod. If BYG is installed, the Nether Wastes biome tag also includes BYG's Magma Wastes biome, so structures will generate there as well. This integration is marked as non-required, meaning the mod works perfectly fine without BYG installed.
FAQ
Do I need to create a new world for the structures to appear?
No. Structures generate in newly loaded chunks, so you just need to explore areas of the Nether you haven't visited before. Any chunks that were already loaded before installing the mod won't have the new structures.
Does this mod add any new blocks or items?
No. Every structure is built entirely from vanilla Minecraft blocks and populated with vanilla entities. The mod only adds structure definitions, loot tables, and the worldgen code to place them. This means you can safely remove the mod from an existing world without leaving behind any unknown blocks.
Why aren't structures spawning in my Nether?
The most common reason is that you're exploring chunks that were already generated before the mod was installed. Travel to completely new areas. Also check that the mod is correctly loaded by looking at your mod list. Some smaller structures like Very Small ruins can be easy to miss because they blend in with the terrain.
Is this mod compatible with other structure mods?
Yes. The mod uses Minecraft's standard structure placement system with unique salt values for each structure set, so it won't conflict with other structure mods. Structures from different mods may occasionally overlap in the same area, but this is true of any combination of structure mods and is handled gracefully by the game engine.
Can I use the /locate command to find these structures?
Yes. All structures are registered under the "mns" namespace. Use commands like /locate structure mns:grave_yard, /locate structure mns:medium_house, or /locate structure mns:smoking_shrine to find specific structures. Tab completion will show all available structure names.
Does this work with Biomes You'll Go (BYG)?
Yes. The mod has built-in optional support for BYG. If BYG is installed, structures that normally spawn in Nether Wastes will also appear in BYG's Magma Wastes biome. This integration is automatic and requires no configuration.
