📖 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.
