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).

What happens in a new world

Searches within a radius (default 96 blocks) around the world spawn for a good location.
Prefers terrain with low height variation (default ≤4 blocks).
Clears the target area before placing (can be disabled).
Places the full building, including block entities, chest contents, and (optionally) entities.
Sets the world spawn and teleports each player on first join (both optional).

Important config options
`(config/starter_cabin/template.nbt)`

Option	Effect
`autoGenerate`	Enable/disable automatic generation in new worlds (default: true)
`copyEntities`	Save and place entities inside the selection
`clearGenerationArea`	Clear the target area before placement
`teleportPlayersOnFirstJoin`	Teleport players to the building on first join
`placementSearchRadius`	How far to search from world spawn (default 96)
`maxSurfaceVariation`	Maximum terrain height difference allowed (default 4)
`maxBlocks`	Maximum number of blocks in a saved template (default 262144)

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.
