Install

1. Install Fabric Loader.
2. Download Litematica and MaLiLib for your exact Minecraft version.
3. Download the matching LMR jar and place all three mods in your mods folder.

Supported: Minecraft 26.1, 26.1.1, 26.1.2, and 26.2 on Fabric.

LMR is client-side and does not bundle Litematica or MaLiLib.

Use

1. Open a schematic or placement Material List.
2. Click Replace beside the material you want to change.
3. Search for and select the new block, then confirm the preview.
4. Choose Overwrite Original or Export as New.

not preserved.
