Description

ADVANCED STRUCTURES: PRE-RELEASE

If you are not sure about downloading this, check out the gallery!

Advanced Structures is a vanilla-style datapack that fills your world with over 70 hand-crafted structures, from humble roadside wells to crumbling giant ruins swallowed by time. Every structure is designed to feel like it has always been there — weathered, overgrown, and waiting to be found.


What's Included

  • 70+ unique structures spanning a wide range of scales and styles
  • Structures range from small details like wells and waypoints to massive multi-piece superstructures generated through Jigsaw
  • Each structure uses carefully tuned decay and aging processors so no two generations look identical — mossy, cracked, crumbled, or half-buried
  • Lore books hidden throughout, telling the story of a world with a history

Lore

The world holds secrets. Scattered across ruins, forgotten temples, and collapsed citadels are the writings of those who came before. Find their journals, their warnings, and their maps. The story unfolds as you explore — there is no quest marker, only curiosity.


Design

Every structure is built to feel vanilla-adjacent — nothing that would look out of place in a Mojang update. Structures respect terrain, use familiar block palettes, and decay naturally into their surroundings. Jigsaw-based structures like the ruined citadel generate differently every time, ensuring no two worlds feel the same.

A special thanks to Complementary Shaders for their awesome shaderpacks!
