Litematica

Litematica is a client-side schematic mod for Minecraft Java Edition, created by masa and now actively maintained by sakura-ryoko. It loads a saved build as a semi-transparent ghost overlay directly in your game world, letting you place blocks inside the outline to recreate structures block by block. A built-in verifier scans the loaded area and highlights every mismatch between your placed blocks and the schematic, making it practical to check large builds or catch placement errors early. Fabric is the actively maintained loader, with releases current through Minecraft 26.2; Forge support is frozen at 1.16.5. Litematica requires the MaLiLib library to load.

How to Install Litematica

Litematica requires both Litematica and MaLiLib. Download both from Modrinth for the same Minecraft version and loader, then drop both .jar files in your mods folder. Fabric gets the current builds; the only Forge build available is for Minecraft 1.16.5.

1. 1.Install Fabric Loader or Forge for your Minecraft version.
2. 2.Download MaLiLib from Modrinth for the same version and loader.
3. 3.Download Litematica from Modrinth for the same version and loader.
4. 4.Place both .jar files in your .minecraft/mods folder.
5. 5.Launch Minecraft. Press M in-world to open the Litematica main menu.

Saving, Loading, and Placing Schematics

To save an existing structure, select a region with Litematica's area selection tool and export it as a .litematic file. To use an external schematic, place the file in your .minecraft/schematics folder and open it through the Litematica menu. Once loaded, the schematic appears in-world as a ghost overlay. You can reposition, rotate, or mirror the overlay before building into it. Litematica reads .litematic (native format), .schematic (MCEdit), and .nbt (vanilla structure files).

• The material list screen tallies every block type in the schematic so you can gather materials before starting.
• A compact material list HUD can be pinned to the corner of the screen while you build, updating in real time.
• Placement modes let you switch between a full transparent overlay, block outlines only, or a simple box.
• Multiple schematics can be loaded simultaneously and toggled individually.

Schematic Verifier and Material List

The schematic verifier scans the blocks in your world against the loaded schematic and sorts mismatches into categories: wrong block type, wrong block state, or missing block. Each error is highlighted in-world with a color-coded outline so you can spot and fix it without consulting a list of coordinates. Run the verifier periodically to catch placement mistakes before they cascade into structural errors across a large build.

Client Side Use and Shader Compatibility

Litematica is a client-side mod only. Modrinth lists server-side support as unsupported, so a multiplayer server does not need it installed, and the overlay and verifier work locally as you build against a shared world. Because the ghost overlay renders through the client, it conflicts with shader packs: rendering breaks in Minecraft 1.21.3 and newer even with Iris, and OptiFine is largely incompatible with the overlay at any version. Disable shaders while placing a schematic, or use Sodium instead of OptiFine for the most reliable rendering.
