📖 About

Compat Structure combines 20+ structure addons into one easy-to-use mod.
Most structures have their own style, themed loot, hidden treasures, secret rooms, or rare blocks.

Instead of installing a bunch of separate structure mods, just drop in Compat Structure — and start exploring!


📃 Features

  • Mod Style: Structures match the theme of each supported mod.
  • Hidden Loot: Secret rooms and rare treasures are tucked away.
  • Mystery Elements: Some builds have hidden goals — solve them for better rewards.

📝 Description

How it works: You install Compat Structure — and let the world handle the rest.
If a supported mod is detected, related structures, dungeons, and features are added into your world.
If not — your world stays clean.
