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.

Tip: Export as new if you want to keep the original schematic untouched. Replacements use the target block's default state; NBT and orientation are not preserved.
