Litematica

Description

Litematica is a modern schematic mod primarily targeting light mod loaders like LiteLoader on MC 1.12.x, Rift on MC 1.13.x and Fabric on MC 1.14+.

There is also a Forge version, but currently only for MC 1.12.2. For later MC versions there are currently only third party ports such as Forgematica.

Litematica has all the main features (plus a bunch more) of the old Schematica mod, except for the printer, which is not planned for Litematica itself, but instead is left to extension mods (see: aria1th printer or the other printer).

Compatibility with shaders

Litematica's rendering doesn't currently work properly with shaders (even with Iris) in 1.21.3+. So when you need to use Litematica (schematic rendering), disable shaders.

In older MC versions the rendering works better with shaders, at least with Iris, but also depending on the shader pack. Some shader packs break the rendering pretty badly, but some used to work pretty nicely. Optifine in general is/was a lot more problematic, pretty much you can't use shaders at all with Optifine if you use Litematica. The general recommendation is to use Sodium (and Iris) instead of Optifine.

Hotkeys

The default hotkey to open the Litematica main menu is M.

Note: If you use a non-QWERTY keyboard layout, then the keys may be different, such as M becoming , on AZERTY.

Warning for multiplayer

The Easy Place mode feature may get you banned on some servers!

The Easy Place feature will always be clicking on the target position's air block, and this can easily be detected by anti-cheat systems. So this can result in at least two things: The block placement will just be rejected and you just get client-side ghost blocks, or some anti-cheat system flags that as cheating and auto-bans you from the server. So before using Easy Place, find out of it's allowed on the server!

If you have Optifine...

In general I don't recommend using Optifine (with Litematica, or otherwise) due to the various rendering issues it causes. Instead I would recommend using Sodium and/or Iris if you want shaders.

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:

• If you get glitchy weird triangles, then in 1.16+ first try updating to the latest Litematica version. If that doesn't work, then set shaders to OFF (not Internal) and restart the game.
• Render Regions probably needs to be disabled to prevent weird rendering issues (the schematic partially rendering in weird places)
• Fast Render might also need to be disabled if there are still some weird HUD/GUI rendering issues

Documentation

There is a wiki. The wiki is still being worked on, and it will probably have a new address at some point (or rather there will be a new wiki in a new location with a lot more coverage).
