❓ FAQ

🧩 How does region placement work?

When placing a saved region into the world:

• In singleplayer, the region content is directly written into the world — blocks, entities, and tile data are fully restored.
• On multiplayer servers, the mod uses a ghost placement technique — the region will appear visually to the client, but the actual server world remains untouched.

  ⚠️ Do not use this feature to mislead or exploit multiplayer gameplay. Always respect server rules.

🔧 Will server-side world editing be supported?

This mod is designed as a basic client-side mod.
Server-side editing support (such as actual block modifications on multiplayer servers) will be introduced via optional companion mods in the future.

📦 What is the .destru file format?

.destru is a custom file format designed to efficiently store block data, block entities, and regular entities across multiple regions with minimal file size.

• Internally, it's a structured .nbt file.
• It prioritizes compactness and performance.
