Litematica for Minecraft 26.3 is release 0.29.1, paired with MaLiLib 0.30.2. Minecraft 26.3 is the third game drop of 2026 under Mojang’s year-based version numbering, and 0.29.1 — published on the project’s Modrinth page on September 27, 2026 — is the current Litematica build made for it. This page gives you the matched pair of files, the exact requirements, and the steps to install or upgrade without the version-mismatch errors that catch most players.
Litematica is the client-side schematic mod originally created by masa. Since Minecraft 1.20.5, the new-version builds on the official Modrinth project have been ported and maintained by community maintainer sakura-ryoko, and the 26.3 build follows that pattern. It remains a Fabric mod: you need the Fabric Loader for Minecraft 26.3 plus two jars — Litematica itself and the MaLiLib library it depends on. Fabric API is not required.
Version Facts
| Minecraft version | 26.3 (2026’s third game drop, year-based numbering) |
| Litematica version | 0.29.1 — the official Modrinth release |
| Litematica file | litematica-fabric-26.3-0.29.1.jar (about 1.9 MB) |
| Required library | MaLiLib 0.30.2 — malilib-fabric-26.3-0.30.2.jar (about 2.0 MB) |
| Release date | September 27, 2026 (both files) |
| Mod loader | Fabric Loader for Minecraft 26.3 |
| Java | Java 25 — the runtime Minecraft 26.3 itself requires |
| Fabric API | Not required |
| License | LGPL-3.0 |
Two details in that table matter more than everything else on this page. First, the MaLiLib version is locked to the Minecraft version: the 0.30.x MaLiLib line belongs to Minecraft 26.3 only, and the MaLiLib build that worked on 26.2 (0.29.x) will stop Litematica 0.29.1 from loading. Second, the Java requirement moved with the game: the 26.x line of Minecraft needs Java 25, not the Java 21 that the older 1.21.x line used. Most launchers handle this automatically when the instance is created for 26.3, but a manually configured Java path pointed at an older JDK is a common cause of instant crashes.

Mirror copies: Litematica mirror · MaLiLib mirror. Site mirror (pCloud) — not an official link. The Modrinth release above is always the reference version.
Both buttons lead to the official Modrinth release files published by the Litematica project. You need both jars: Litematica will not start without the matching MaLiLib build in the same mods folder. The full version table for every Minecraft release is on the download page.
Installation Notes
- Install Fabric Loader for 26.3 first. Run the Fabric installer once for Minecraft 26.3 and launch the game a single time so the Fabric profile and folders exist before you add mods.
- Drop both jars into the same mods folder. Place litematica-fabric-26.3-0.29.1.jar and malilib-fabric-26.3-0.30.2.jar side by side in .minecraft/mods. Do not unzip them.
- Remove the old pair when upgrading. If 0.28.x Litematica or a 0.29.x MaLiLib jar is still in the folder, delete it — Litematica and MaLiLib must always be replaced as a matched pair.
- Check your Java. Minecraft 26.3 needs Java 25. If the game closes instantly with a class-version error, the launcher is pointing at an older Java; let the official launcher manage the runtime, or point third-party launchers at a Java 25 install.
- Open the menu with M. In game, the M key opens the Litematica main menu and M + C opens the configuration. On AZERTY keyboards the menu key is the comma key instead.
Upgrading from Minecraft 26.2
The upgrade from 26.2 (Litematica 0.28.8) to 26.3 is a file swap, not a migration. Your schematics live in the .minecraft/schematics folder, independent of the mod jars, and .litematic files you saved or downloaded under 26.2 can be loaded by the 0.29.1 build in the usual way — the schematic format does not change between these two game drops. Your Litematica settings are likewise stored separately from the jar, so replacing the files does not wipe your configuration.
What must change is the dependency pair. Delete litematica-fabric-26.2-0.28.8.jar and its MaLiLib 0.29.x jar, then add the 0.29.1 and 0.30.2 files from this page. Leaving the old MaLiLib in place is the single most common upgrade mistake: the Fabric Loader will report that Litematica requires a different MaLiLib version range and refuse to start. If you run other masa mods (MiniHUD, Tweakeroo, Item Scroller), they share MaLiLib, so update those to their 26.3 builds in the same pass — they all need the 0.30.x library line.
One rendering note for players coming from 26.2 with shaders: on the current Minecraft line, Litematica’s projection rendering does not work correctly while shaders are active. If your schematic looks broken or invisible after the upgrade, turn shaders off before troubleshooting anything else — with shaders disabled, Sodium can stay installed and causes no problem.
Frequently Asked Questions
What is the latest Litematica version for Minecraft 26.3?
Litematica 0.29.1, released on September 27, 2026 on the project’s Modrinth page. It requires MaLiLib 0.30.2 — the two files must be installed together.
Do I need Fabric API to run Litematica 0.29.1?
No. Litematica needs the Fabric Loader and MaLiLib only. The project’s own documentation states that Fabric API is not needed, even though many other Fabric mods require it.
Can I use my Minecraft 26.2 schematics on 26.3?
Yes. Schematics are stored as .litematic files in your .minecraft/schematics folder, outside the mod jars. Files saved or downloaded under 26.2 load normally in the 0.29.1 build — just replace the Litematica and MaLiLib jars with the 26.3 pair.
Why does Minecraft fail to start after I update to 26.3?
Almost always a leftover file: an old MaLiLib (0.29.x or earlier) or the old Litematica jar is still in the mods folder. Remove both old jars so only litematica-fabric-26.3-0.29.1.jar and malilib-fabric-26.3-0.30.2.jar remain, and make sure the launcher is using Java 25.
