How to use it in 4 s

teps

• 1.Build your structure, then place a Spawn Carpet inside it where you want players to appear.
• 2.Hold the Building Saver item, right‑click one corner of the building, then right‑click the opposite corner – a selection outline appears.
• 3.Sneak + right‑click any block to save the selected area as a template.
• 4.When you create a new world, the mod will automatically find a suitable flat spot near spawn, place your building, and set the world spawn to the carpet position.

Key items

Building Saver – a carrot‑on‑a‑stick styled tool for selecting and saving.

Spawn Carpet – a marker block that records the spawn point; it is removed after saving (configurable).

Notes

• The template is saved to config/starter_cabin/template.nbt
• Each world generates the building only once – delete world data to force regeneration.
• If placement looks off, increase placementSearchRadius or lower maxSurfaceVariation.
• Recommended workflow
• Build and save your structure in a test world.
• Create a new world to verify the generation.
• Tweak config values if needed, then re‑save the template after major changes.
