Litematica is a new schematic mod written from scratch, and is targeting light (client-side) mod loaders like LiteLoader on 1.12.x and Rift on 1.13.x.


NOTE: Litematica also requires the MaLiLib library mod:


NOTE: If you have Optifine installed, then there are some options that you most likely will need to disable in Optifine, or otherwise it will break the schematic rendering:

  • Render Regions needs to be disabled
  • Shaders need to be set to OFF, or alternatively disable VBOs in the vanilla Video settings, and disable both the 'schematicOverlayModelOutline' and 'schematicOverlayModelSides' options in the Visuals category
  • Fast Render might also need to disabled if there are still some weird HUD/GUI rendering issues

The mod is still under development, and many of the planned "extra" features (for example some of the "tool modes") haven't yet been implemented fully or at all.


Currently it's otherwise on feature parity with (and in my opinion in many ways ahead of) Schematica, except it doesn't have the "full/automatic" printer mode yet.


The default hotkey to open the in-game config GUI is M + C.


If you have questions or need help with something, the best/fastest way to get answers is currently the #masa-mods-feedback channel on the SciCraft Discord server.


A quick howto to some of the basics of the mod is here:


A quick video explanation of the current Area Selection mode (this will change soon, to improve the user friendlyness a bit especially for new users):


Quick howto to loading schematics:

  • First of all, the 1.13.2 version of Litematica can't currently (in the first uploaded build, 20181212) load old non-Litematica schematics (due to the block ID related changes in 1.13). I will try to add conversion support for old schematics, but it probably will never work 100% correctly
  • The best way to use old schematics, is to create a new temporary, empty world in 1.12, and then use MCEdit-Unified to place the old schematic there, then load that world in 1.13.2 allowing Minecraft to convert the blocks in the world, and then make a new schematic from that world using Litematica.
  • After you have a Litematica schematic ("litematic"), place it inside the schematics/ directory inside the .minecraft directory of your instance
  • Then open the main menu (M by default), go to Load schematics to memory, and select your schematic using the browser
  • Make sure the Create placement option is enabled (to skip an extra step of going to the loaded schematics list and creating a placement from there), and click Load to memory
  • Now you can go to Show schematic placements, and click Configure for the placement, and input/adjust the coordinates
  • You can also use the "tool item" (by default a stick, change it in the Generic configs) or hotkeys to nudge around the placement. Using the tool, it works by being in the Schematic Placement mode (Ctrl + scroll to change the mode), and then Left Alt + scrolling while looking in the direction you want to nudge the placement. Using the hotkeys it's the same idea, except that you don't need to hold the "tool item" in hand.

M + C opens the in-game config GUI. On the Render Layers tab you can switch to for example the Single Layer, or All Below, or Layer Range etc. rendering modes. Also check the available hotkeys for various things on the Hotkeys tab, they have a short comment explaining them when you hover over the name.
