This blueprint system is built for high compatibility, not just saving blocks. It already supports saving and restoring Swivel Bearing connections, Rope Winch rope links, Drive By Wire connections, Create contraptions, and Super Glue, so complex Sable/Create builds can survive copy, export, and placement with their important runtime links intact.

It also includes a SubLevel management tool for recovering SubLevels that get lost somewhere in the world. You can locate them and teleport them back, including connected joints, making it much easier to rescue misplaced or orphaned physics structures during testing and building.

Introduction

Sable sub-levels can contain moving blocks, block entities, entities, and modded state that often stores references to positions, UUIDs, constraints, or manager-owned data. A normal copy-paste workflow is not enough for these structures because copied data must stop pointing back to the original world objects.

Sable Schematic API focuses on that remapping problem:

• Blocks and block entities can clean or rewrite saved NBT.
• Entities can be transformed, skipped, or restored with custom logic.
• Multi-block or externally managed systems can store blueprint sidecar data.
• Placement maps source sub-level UUIDs and blueprint-local block references to newly allocated placed sub-levels.

The mod also includes a simple in-game tool so blueprints can be tested without typing coordinates every time.

Features

• Save and load Sable sub-level blueprints.
• Save blocks, block entities, regular entities, and Create contraption entities.
• OP-only commands for saving and loading.
• In-game blueprint tool:
  • Select an area with left click.
  • Open the UI with Tab.
  • Save local blueprint files under Sable-Schematics/.
  • Upload and place selected local blueprints with right click.
• Developer extension points:
  • Block mappers.
  • Entity mappers.
  • Global blueprint events and sidecar data.
• Create compatibility:
  • Contraption entity anchor remapping.
  • Super Glue save and restore through sidecar data.
• Simulated Project compatibility:
  • Swivel-bearing and plate reconnection.
  • Rope-winch / rope-connector rope strand restoration.
  • Launched plunger entity skip rule.

Requirements

Required

• Minecraft 1.21.1
• NeoForge 21.1.228+
• Sable 2.0.0+
• LDLib2 2.2.17+

Optional Compatibility Targets

• Create 6.0.10+
• Simulated Project 1.1.3+

Compatibility mappers are only registered when the corresponding optional mod is loaded.

Usage

Blueprint Tool

Give yourself the tool:

/give @p sable_schematic_api:blueprint_tool

Basic controls:

• Hold the tool and left click to select the start and end points.
• Shift + left click clears the current selection and selected blueprint.
• Press Tab while holding the tool to open the blueprint UI.
• Use Save to export the selected area to the client-side Sable-Schematics/<name>.nbt folder.
• Select a local blueprint in the UI, then right click to upload it to the server and place it at the look target.

Tool-based saving and loading also require OP permission, and the player must be holding the blueprint tool.

Important Notes

• This is an experimental API mod, not a stable long-term storage format yet.
• Back up important worlds before testing blueprint save/load workflows.
• Current blueprints mainly copy Sable sub-level contents. Regular root-world blocks are not part of the same reference mapping.
• Rotation and mirroring are not exposed as stable placement features yet. Current compatibility behavior mainly assumes translation.
• Blueprint NBT format is currently v1 and does not support legacy plot payloads.
• Optional compatibility behavior depends on the runtime NBT and API structures of the targeted Create and Simulated Project versions.
• This mod is intended for controlled testing, compatibility development, and early blueprint workflow experiments.
