litematica-extra
by shun40
Litematica extension adds fixes, backported features and a V6 schematic export to the Litematica schematic tool for Minecraft versions below 1.21.
What it does
The extension is built on Litematica and brings in fixes and features that were not part of its release line for these game versions. Among the additions is a V6 schematic export option, so a build can be saved in that format. Schematics can be exported from the Litematica menus once the extension is loaded alongside its base mod.
Pasting entities across chunk boundaries no longer duplicates them, which matters on servers where a build spans several chunks. Reading schematic metadata now uses an NBT scanner in place of a full read, which the author describes as better performance. Litematica itself is a dependency, and Fabric API is needed on the Fabric loader.
The mod is released for Fabric only, across seven game versions, with v2.2.3-mc1.20.6 as the latest file for 1.20.6. It is client-side only, so servers run without it, and it is open source under the GNU Lesser General Public License v3.0 only.
Key features
V6 schematic export
Schematics can be written in the V6 format, adding an export option next to the formats Litematica already writes.
Entity paste fix
Duplicate entities no longer appear when a pasted build crosses chunk boundaries, including on multiplayer servers.
Faster metadata reading
Schematic metadata is read with an NBT scanner instead of a full read, which the author lists as a performance change.
Backported fixes
Several fixes and features from newer Litematica work are carried back to the 1.20.x line of the tool.

Use cases
Who it’s for: Players who use Litematica on Minecraft 1.20 – 1.20.6 and want its fixes and the V6 export without updating to a newer game version. The mod needs only the player's client, so server owners do not have to install it.
How it compares
Litemoretica is a Litematica fork for Fabric and Quilt, open source under the MIT License, and it requires the client while the server stays optional. It covers 1.19 – 1.21.1, a wider range than this extension, which targets 1.20 – 1.20.6 only. Litematica Companion is client-side only, open source under the MIT License and published for Fabric across 1.21 – 26.2, so it targets game versions after this extension's range.
