NSPrefab – Building Blueprints

NSPrefab — Take Your Builds With You

Turn a favorite build into a blueprint. Inspect it before placing it, find the right position, and move it again when it is time for a new home.

NSPrefab brings structure saving, interactive previews, placement history and building relocation into one set of in-game tools.

Save your own structures

Use the Structure Selector to mark two corners and save the selected area as a blueprint. Choose whether to include entities, give the structure a name, and use the Structure Browser to find saved builds.

See the build before you place it

Open an interactive 3D preview with a layer-by-layer reveal. Rotate, pan and zoom to inspect the design, or cut away upper layers to look inside. The in-world placement preview also features smooth rotation transitions to help you judge orientation before confirming placement.

Keep a record of your builds

Press Ctrl+Z in the world to open placement history. Keep track of your 10 most recent placements, including their names and locations. Favorite a record to keep it when the recent list rolls over.

Each record offers two different actions:

• Undo restores the area to its state before placement and returns the original blueprint if one was consumed.
• Reclaim captures the current contents of the original building bounds. Review the preview, confirm it, and name the new blueprint. Once the data is saved, the captured contents are removed from the old location and a new blueprint is returned for placement elsewhere in the same world.

Reclaiming includes later changes inside the original bounds, so you can move a house after furnishing or renovating it. It can include blocks, container contents and supported saveable entities; players remain in place. Extensions outside those bounds are not included.

Built for larger projects

Preview preparation and world operations are processed incrementally to spread work across frames and server ticks. The mod also includes a light block and wireless controller for lighting your builds.

Quick controls

• Hover over a blueprint in your inventory and hold W to open its preview.
• In the preview: left-drag to rotate, right-drag to pan, and scroll to zoom.
• Ctrl+left-click cuts layers; Space restores all cut layers. Home recenters the view, and R replays the reveal.
• In the world: right-click with a blueprint to set its placement preview, then Shift+right-click to confirm placement.
• Ctrl+Z in the world opens placement history instead of immediately removing a building
