Litematica is a new schematic mod written from scratch, and is targeting light (client-side) mod loaders like LiteLoader on 1.12.x, Rift on 1.13.x and Fabric on 1.14+.

The default hotkey to open the in-game config GUI is M + C. If you are for example on AZERTY keyboard layout instead, then the keys are different, and M + C becomes , + C instead, etc.

FAQ - please read first if you have questions

• Q: The main menu and the config menu don't open with M and M + C
• A: 1.) Check that the mod is installed and working: check if you see the orange Litematica text on the F3 screen.
  2.) If you are on a non-QWERTY keyboard layout, then the default hotkeys are different. For example on AZERTY the M key is , (comma) instead, so the config menu hotkey for example is , + C. I'm looking for a solution to this issue.
• Q: How do I rotate a schematic (placement)?
• A: In the Placement configuration GUI. You can open it (for the currently selected Placement) with a hotkey, or you can go via the Main menu -> Schematic Placements -> Configure.
• Q: How do I only render one layer at a time
• A: You can control the rendered layers on the Render Layers tab inside the in-game config menu (via the Main menu -> Configuration Menu, or the default hotkey M + C
• Q: How do I change blocks in the schematic? Is there a /schematicaReplace command?
• A: 1.) There is no command, but there is the Schematic Rebuild mode, which allows you to change, add and remove blocks from the schematic.
  2.) To change all blocks of one type to another, set a hotkey for the schematicRebuildReplaceAll keybind, switch to the Schematic Rebuild mode (bottom left button in the Litematica menu)
  3.) Hold the new block you want to use, and while holding down that rebuild hotkey, right click on the block type you want to replace
  4.) You can limit the part of the schematic where the blocks get replaced in using the Render Layers, and you can limit the replacement to a certain sub-region by selecting that sub-region (in the Placement Configuration GUI, click on the sub-region so it's hilighted in white outline)
• Q: Is there a printer like in Schematica?
• A: 1.) There is no printer for survival yet. It is on my TODO-list and will be added at some point.
  2.) For Creative mode there is the Paste Schematic in world tool mode, which places the entire schematic at once in a single player world, or using setblock commands in multiplayer.
• Q: I get an error "Failed to load schematic" when trying to load a '*.schematic' file in 1.13+.
• A: 1.) The 1.13+ versions of Litematica can't currently load old 1.12 schematics or even Litematica files properly, due to the "flattening" in Minecraft 1.13, which basically renamed anc changed some block properties.
  2.) Support for importing old *.schematic schematics is currently being worked on. Support for properly loading (= converting) 1.12 Litematica files will be worked on after that.
  3.) Currently the way to use old schematics in 1.13 or 1.14 is to:
  
  • Create a temporary 1.12 (flat) world.
  • Place the schematic there, using either MCEdit-Unified, or the 1.12 version of Litematica in the Paste Schematic in world tool mode (use the executeOperation hotkey to execute the Paste operation, once the Placement is in place)
  • Load that world in the new MC version, allowing vanilla to convert the structure in the world
  • Make a new Litematica schematic from the structure from that converted world

The mod is still under development, and some of the planned "extra" features (for example some of the "tool modes") haven't yet been implemented fully or at all.
Currently it has everything else Schematica had, except the "full/automatic" printer hasn't been implemented yet, but it's on my TODO-list.

A quick howto to some of the basics of the mod is here: https://pastebin.com/qVWXiy9h (outdated as of the 2019 June builds!)

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.

Rift 1.13.2 installation:

- Make sure you have Java 8 installed (Java 9 or newer won't work with Rift)

Option 1 - Use the MultiMC launcher (I personally recommend this!):

• Get MultiMC from https://multimc.org
• Download this zip: https://cdn.discordapp.com/attachments/453662800460644354/583233078541942785/mmc_rift_1.13.2_jitpack_aeee80c1fb-1.zip
• In MultiMC, click Add Instance from the top
• Select Import from zip on the left, and select that zip file you downloaded from above. Give the instance a name on the top, and click OK to finish and Rift will get installed to that instance.
• If you need further help with MultiMC, I have a video here: https://www.youtube.com/watch?v=HzR9oRld08A

Option 2 - To install Rift 1.13.2 to the vanilla launcher:

• First download the Rift installer from here: https://www.jitpack.io/com/github/Chocohead/Rift/ jitpack-aeee80c1fb-1/Rift-jitpack-aeee80c1fb-1.jar
• Close the Minecraft launcher if you have it running
• Double click the Rift jar it to run it
• If it installed successfully, then open the equivalent of the file C:\Users\masa\AppData\Roaming\.minecraft\versions\1.13.2-rift-1.0.4-SNAPSHOT\1.13.2-rift-1.0.4-SNAPSHOT.json ( depending on your OS and user name etc.) in a text editor
• Inside the libraries array, on the com.github.Chocohead:Rift line, replace the SNAPSHOT string with aeee80c1fb-1
• Save the file
• Done.
• The game should now launch with Rift installed when you launch it using the 1.13.2-rift-1.0.4-SNAPSHOT profile in the vanilla launcher.
• Image of how the json file should look like after the edit:
