Litematica

Severe vulnerability in 1.21+ versions of the mod

See the announcement post here for details:

https://old.reddit.com/r/litematica/comments/1up8uqk/important_announcement_litematica_vulnerability/

As a summary, everyone using MC 1.21+ versions of Litematica should update to the latest available mod versions immediately!!

The vulnerability does not exist in the 1.20.x and older mod versions. With the affected mod versions, connecting to potentially any server might transfer malware to your system. Single player is not at risk. But update the mod!

See this about MC 1.20.5 and later versions

TL;DR; I won't maintain the 1.20.5+ versions myself anymore, at least for now. There are ports by Sakura-Ryoko. They will be here once they are more stable, see the post for the links and details before then.

Description:

Litematica is a new schematic mod written from scratch, and it is primarily targeting light mod loaders like LiteLoader on 1.12.x, Rift on 1.13.x and Fabric on 1.14+. There is also a Forge version for 1.12.2, but not yet for 1.14.4+ (but Forge ports for 1.14.4+ are also planned, see below).
It has all the features of the old Schematica mod except for the printer (which is not planned for Litematica itself, but instead is left to extension mods), plus a bunch more.

• The main feature of a schematic mod is to display a "hologram" version of a structure, which shows you exactly how to build the structure and where to place the blocks. It also includes a (configurable) overlay to highlight missing, extra or wrongly placed blocks.
• Litematica also includes a nice Material List, including a Material List HUD, to help you collect the materials needed for the build.
• There is also a Schematic Verifier feature, including an overlay, which you can use to scan the entire schematic area and look for any mistakes. This can be extremely useful especially with technical/redstone builds, where tiny mistakes can break everything.
• There are also several Creative-mode-only helper features, such as Fill, Replace, Delete and also a Paste mode for "pasting" schematics into the world (immediate/direct in single player, using /setblock commands in multiplayer).

NOTE: Litematica also requires the MaLiLib library mod:

WARNING: 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!

About Forge ports for 1.14.4+
Forge versions for 1.14.4 and later are planned.
Still no ETA for the "official port", which will only be done from the still being worked on new development code. But ZacSharp already ported the current 1.16.4 Fabric version to 1.16.5 Forge. That port is available here: https://legacy.curseforge.com/minecraft/mc-mods/litematica-forge

Some more info and discussion about the Forge port/builds is here: https://github.com/maruohon/litematica/issues/234

There are also at least a couple of other 3rd party Forge ports on GitHub and at least one on Modrinth. I haven't tested those myself, so I can't say anything about how well they work.

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.

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

Snapshot versions and latest development builds

There are sometimes newer "development" or snapshot versions of my mods available here: https://masa.dy.fi/mcmods/client_mods/
Lately I've stopped making releases for MC snapshots, as it's mostly a waste of my limited modding time and energy. Snapshot releases maye start again at some point, if I ever get the elusive but often mentioned "new code versions" of the mods actually released to the public first. I geuss time will tell.

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: There is no command, but there is the Schematic Rebuild mode (should be called Schematic Edit mode...). See the wiki here for more details: https://github.com/maruohon/litematica/wiki/schematic_editing
• Q: Is there a printer like in Schematica?
• A: 1.) There is no printer for survival, and it's not planned for Litematica itself. There are at least two separate extension mods to add a printer. See: https://github.com/aria1th/litematica-printer or https://github.com/aleksilassila/litematica-printer
  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 - 1.16 versions of Litematica can't currently load the Sponge schematic format yet. That format is used for example by World Edit in 1.13+. Although those schematics should preferably be named with the *.schem file name extension, many web sites use the *.schematic extension, which makes them hard to tell apart from the old, completely different MCEdit/Schematica format, which Litematica can already load. Full support for the Sponge format exists in the main development version in 1.12.2, and a "quick hax" temporary support for just loading that format also exists in the 1.17+ mod versions. It will also come to the other versions with the next bigger update.
  2.) Currently the way to load Sponge schematics with Litematica is:
  • Create a temporary (flat) world.
  • Place the schematic there using World Edit (quick guide: https://old.reddit.com/r/Minecraft/comments/kt2znv/convert_schem_file_to_litematic_file/gilwla8/)
  • Make a new Litematica schematic from the placed structure from that 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.

Here is a Reddit post that explains the very basics of the mod:

Here are some tutorial videos for the basics of the mod. A more detailed, "official" tutorial video is planned after I finish some changes and still missing features I'm still working on for the mod.
