Advanced Structures: Pre-Release
Advanced Structures is a NeoForge data pack that places more than 70 hand-crafted structures into newly generated world terrain, from roadside wells to multi-piece citadels.
What it does
Advanced Structures is published as a vanilla-style data pack for NeoForge, and it needs no separate mod beyond the vanilla game. The structures range from small details such as wells and waypoints to large multi-piece superstructures built through jigsaw generation, so each new world arranges its ruins and citadels differently. Structures follow the surrounding terrain and use familiar block palettes, and a decay processor gives them aged, mossy, cracked and half-buried states that look different from one generation to the next.
Story elements are spread through the ruins. Lore books, journals, warnings and maps are hidden among forgotten temples and collapsed citadels, and they tell the history of the world for players who explore. The data pack works alongside most other data packs, including packs that replace the same structure sets or template pools.
The mod is in early pre-release, so bugs, missing features and balance changes are expected before the full release. A full release is expected in late fall 2026, and it may add Nether and End structures along with more lore and fixes. The project is closed source, and it is released under All rights reserved.
Key features
Over 70 structures
More than 70 structures are added to generated terrain, covering wells, waypoints, ruins and large superstructures.
Weathered decay states
A decay processor ages each structure into mossy, cracked, crumbled or half-buried variants that differ between worlds.
Hidden lore books
Journals, warnings and maps are scattered through the ruins and reveal the history of the world as players find them.
Jigsaw-based citadels
Large structures such as a ruined citadel are assembled from jigsaw pieces, so their layout varies from world to world.
