Create: Instant Schematics

Overview

Have you ever wondered why Create's Schematic Table takes so long to upload large schematics?

Why wait, when the schematic already exists?

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

Beyond instant loading, the mod also introduces multiplayer quality-of-life features, including sharing schematic holograms with other players and synchronizing hologram movements in real time, making collaborative building significantly easier.

Instead of waiting for the Schematic Table to upload large files every time, 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 builds directly on Create's existing schematic system, allowing Create to handle hologram previews, placement settings, and printing exactly as intended. This means full compatibility with Create's native schematic workflow while eliminating unnecessary waiting.

Features

• Instantly load an existing .nbt schematic with a command.
• List available schematics without leaving the game.
• Recycle a written schematic back into an Empty Schematic.
• Share a loaded schematic directly with another online player.
• List and clear received shared schematics from the client schematic folder.
• Provides tab completion for available schematic filenames.
• 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.

Update 1.0.0

Version 1.0.0 expands the command workflow:

• /cis list lists the .nbt schematics available to you.
• /cis share <player> sends your currently loaded schematic to another online player.
• /cis sharedlist lists schematics you have received through CIS sharing.
• /cis load <filename> now supports tab completion for available schematic files.

How To Use This Mod

1. Install Create: Instant Schematics. See the installation instructions below.

2. Choose the workflow that matches your setup:

   • Singleplayer: Simply use the provided commands to load or unload schematics.
     • /cischematic load <filename>
     • /cischematic list
   • Multiplayer Server: Continue with the steps below.

3. 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.

4. If your server host does not allow direct file uploads (for example, Aternos), upload the schematic once using the Create's 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.

5. To share a loaded schematic with another online player, hold the written schematic and run /cischematic share <player>. The receiving player gets a client-side copy for previewing and reuse.

Commands

/cischematic load <filename>
/cischematic list
/cischematic unload
/cischematic share <player>
/cischematic sharedlist
/cischematic clearshared

Short aliases are also available:

/cis load <filename>
/cis list
/cis unload
/cis share <player>
/cis sharedlist
/cis clearshared

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

Example:

/cischematic load "example.nbt"

/cischematic load <filename> supports tab completion for available .nbt files.

Command summary:

Command	Description
/cischematic load <filename>	Converts a held Empty Schematic into a written Create Schematic for an existing .nbt file.
/cischematic list	Lists the schematics available in your schematic source folder.
/cischematic unload	Converts a held written schematic back into an Empty Schematic without deleting the file.
/cischematic share <player>	Shares the held loaded schematic with another online player.
/cischematic sharedlist	Lists CIS shared schematics stored on your client.
/cischematic clearshared	Deletes CIS shared schematic files from your client schematic folder.

Schematic Files

In singleplayer, schematics are loaded from:

schematics/<filename>.nbt

On multiplayer servers, schematics are loaded from:

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

For example, player Steve on a multiplayer server 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.

Schematics received through /cischematic share <player> are saved on the receiving client as cis_shared_*.nbt files under:

schematics/

Use /cischematic sharedlist to list those received files, or /cischematic clearshared to remove them.

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.
