Litematic Generator

Build the shape. Save the schematic.

Litematic Generator turns shapes, text and mathematical formulas into Minecraft schematics. The 2.0 update introduces native .litematic export and a simple in-game interface for Fabric, NeoForge and Quilt.

Release transition: This guide describes version 2.0. New builds are being prepared for publication. Older downloads use the previous command-based workflow and export .nbt files. Check the version number and changelog before downloading.

What can you create?

Generated shapes use smooth stone. Files are saved locally, ready for your schematic workflow.

From idea to schematic

1. Install the JAR for your exact Minecraft version and mod loader in your instance's mods folder. Replace the previous Litematic Generator JAR.
2. Enter a world and press K.
3. Choose a generator and enter your dimensions, text or formula.
4. Select Generate .litematic. Generation runs in the background.
5. Find the result in your instance's schematics folder. Use Copy file path to locate it, or Load schematic when a compatible Litematica is installed.

Change the shortcut: Open Minecraft's Controls → Key Binds → Miscellaneous → Litematic Generator. You can also reach this page through Mod Menu → Litematic Generator → Configure on Fabric/Quilt, or Mods → Litematic Generator → Config on NeoForge.

The generator opens inside a world. There are no generator buttons in the title or pause menus.

Create with formulas

Use coordinates x, y and z, centered on the generated region. For a sphere with radius 16, try:

sqrt(x*x+y*y+z*z)-16

• Surface mode selects finite values close to zero: absolute value ≤ 0.45.
• Filled mode selects finite values ≤ 0.
• Supported operators: + − * / ^, parentheses, constants pi and e.
• Supported functions: sin, cos, tan, abs, sqrt, log, exp.

Choose a region radius large enough to contain your shape. Scaling an expression changes the thickness selected in surface mode.

Native .litematic export

Version 2.0 writes compressed Litematic v7 files directly, with a compact block palette and packed block states. Each file includes the Minecraft data version of the game that generated it.

Litematica is optional for generating and saving files. To view a schematic in the world, install a compatible schematic viewer separately. The Load schematic integration requires a compatible Litematica installation; availability depends on your Minecraft version and loader. Loading a schematic does not automatically build it in the world.

Compatibility & requirements

Download availability is shown in the Versions tab. Match both the loader and exact game version; snapshots are outside this update's build matrix.

Using an older release?

The previous releases export .nbt files and use client commands:

/generatecircle <radius> <orientation>
/generatesphere <radius>
/generateparabola <width> <height>
/generatetext <fontsize> <text>

The instructions above for K, the GUI and .litematic apply to 2.0.
