Create: Instant Schematics

Overview

Have you ever wondered why the Create's Schematic Table feels like it takes forever to load large schematics?

Why can't we just skip the waiting?

Well… now you can.

Create: Instant Schematics is a lightweight Create addon that lets server players instantly convert a held Empty Schematic into a written Schematic for an existing server-side .nbt file.

Instead of waiting for the Schematic Table to upload large files, simply run a command and start building immediately.

The mod does not introduce a custom schematic format, GUI, uploader, printer, or hologram renderer. Instead, it reuses Create's existing schematic system, allowing Create to handle hologram previews, placement settings, and printing exactly as intended.

Features

Instantly load an existing .nbt schematic with a command.
Recycle a written schematic back into an Empty Schematic.
Uses Create's native schematic preview and placement behavior.
Supports filenames with spaces when enclosed in quotes.
Validates schematic paths to prevent directory traversal.
Preserves schematic files when unloading a schematic item.
Synchronizes the client cache so Create can immediately display the hologram preview.

How To Use This Mod

Install Create: Instant Schematics. See the installation instructions below.
Choose the workflow that matches your setup:
- Singleplayer: Simply use the provided commands to load or unload schematics.
- Multiplayer Server: Continue with the steps below.
Ensure the desired .nbt schematic is available on the server under:

   schematics/uploaded/<playerName>/

Once the file is there, use /cischematic load <filename> to instantly convert a held Empty Schematic into a written Create Schematic.

If your server host does not allow direct file uploads (for example, Aternos), upload the schematic once using Create's normal Schematic Table. After the file has been uploaded to the server, you can reuse it instantly with the provided commands without waiting for another upload.

Commands

/cischematic load <filename>
/cischematic unload

Short aliases are also available:

/cis load <filename>
/cis unload

If the filename does not end with .nbt, the extension is appended automatically.

Example:

/cischematic load "example.nbt"

Schematic Files

Schematics are loaded from:

schematics/uploaded/<playerName>/<filename>.nbt

For example, player Steve would load:

schematics/uploaded/Steve/example.nbt

Running /cischematic unload only recycles the held schematic item. It does not modify or delete the .nbt file.

Notes

Very large schematics may still cause short freezes while Create loads and renders the hologram preview. This mod bypasses the upload process but intentionally relies on Create's native rendering and placement pipeline, so overall performance for extremely large schematics remains limited by Create and Minecraft.
