Litematica Troubleshooting
Litematica problems look alike from the outside — the mod “just doesn’t work” — but they split into a handful of distinct causes. Find the symptom that matches yours below; each guide isolates one problem and fixes it step by step.
Get the Matched Download Pair
Half of all Litematica problems are one wrong file. Every download row lists Litematica and the MaLiLib build for the same Minecraft version, together.
Reinstall Cleanly, Step by Step
If your setup is a mess of old jars and half-finished attempts, the install guide rebuilds it in order — Fabric Loader, Litematica, MaLiLib — with checks at the end.
Won’t Start
The game or the mod refuses to run at all. Start with the symptom index, then drill into the specific failure.
Litematica Not Working? Fix It by Symptom
Start here: the mod is missing, the menu won’t open, the hologram is invisible, or blocks won’t place — four symptoms, four different fixes.
Litematica Crashing on Startup
The game closes or leaves a crash report: wrong Java, an old Fabric Loader, or a broken mod pair — and how to read the crash report itself.
Menu Not Opening (M Key)
You press M and nothing happens. Key conflicts with other mods, the AZERTY comma-key case, and rebinding the menu key in the config.
Files & Loading
The mod runs, but your schematic file will not appear, will not load, or loads without rendering anything.
Schematics Not Showing Up
The file is in the wrong folder, was never loaded through the menu, or a placement exists with its rendering switched off. Three causes, checked in order.
Guide: How to Load Schematics
The full workflow when it works: the schematics folder, the Load Schematics menu, and managing placements.
Errors
A specific message is on screen. Match the wording to the guide — the message names the problem more precisely than it first appears.
MaLiLib Version Mismatch
“Mod ‘Litematica’ requires ‘malilib'”, or the installed MaLiLib is outside the required range. The matched-pair table and the duplicate-jar trap.
Unsupported Schematic Version
Including “unsupported schematic version 7”: the file was saved by a newer Litematica than yours. How to re-save, update, or re-export it.
Building Tools
The hologram is up, but the tools that help you build against it are not behaving.
Easy Place Not Working
Easy Place is on and places nothing: prove it in single player first, then check activation, server anti-cheat rejection, versions and mod conflicts.
Printer Not Working? Read This First
There is no printer in Litematica — officially, it was never planned. What you are probably using, what Easy Place does instead, and where extensions get support.
Version questions are the other half of most problems: the latest version page shows the current Litematica + MaLiLib pair, and the version history lists the matched builds for every Minecraft version. If your problem started right after a Minecraft update, check those two pages before anything else.
