LitematicaMatReplace (LMR)
by NullKeeper
LitematicaMatReplace adds a Replace button beside each material in Litematica's Material List, so one block type can be swapped across a schematic in a few clicks.
What it does
Each row in the placement Material List carries a Replace button styled to match Litematica's interface. Clicking it opens a search field where the new block can be typed by name or namespaced ID, and rendered block previews help pick the right one. After confirming the preview, the player chooses whether to overwrite the original schematic or export a new copy.
The mod is a client-side tool, so only the player running the client needs it and servers can run without it. It requires Fabric API, Litematica and MaLiLib, and targets Fabric for 26.1 – 26.2, with builds covering 26.1, 26.1.1, 26.1.2 and 26.2. The latest file, 0.1.0 for 26.2, was published on 2026-07-28.
The project is open source under the GNU General Public License v3.0 only, with public source code and an issue tracker. Its author is NullKeeper, and the mod is categorized under Utility.

Who it’s for: Players who load Litematica schematics in single-player or on a client that connects to a server, and who want to substitute one block type across a build without editing each position.
How it compares
Better Litematica Materials List is also open source, under the GNU General Public License v3.0 only, and runs client-side only on Fabric for 26.1.2, extending the same material list. Cloudmatica is client-side only on Fabric for 26.1.2 – 26.2 under the MIT License and is not open source, so its source is not public, while LitematicaMatReplace is open source under GPL-3.0 only.
