Litematica Zone Focus

Litematica Zone Focus is a client-side Litematica addon for Fabric that lets you build a schematic piece by piece.

A placed schematic is split into zones. You pick the zone you're working on right now, and the schematic is rendered, counted and verified only inside that zone — the rest stays out of the way until you get to it.

Requirements: Fabric Loader, Fabric API, MaLiLib and Litematica. Client-side only — nothing to install on the server, and it works on vanilla servers.

What it does

• Splits a schematic into zones — as a grid (set either the number of zones per axis or the size of one zone in blocks, with a live preview of how many zones you'll get and how big they'll be), by dragging out a zone with your mouse, or from a Litematica selection.
• Works inside the active zone only — rendering, misplaced-block detection, layer-by-layer building and every other calculation are limited to the zone you selected.
• Tracks progress for every zone — percentage, blocks remaining and distance to the zone. The list can be sorted by any of them, or by zone number.
• Reduces the rendering load on large schematics — geometry outside the active zone isn't built at all, so there's less to draw and fewer chunk rebuilds. How much you gain depends on the schematic and your zone size.
• Lets you mark zones with the mouse — a new hotbar slot: hold Attack (left mouse button by default) and drag to mark out a zone, release to save it.
• Verifies the schematic within the zone — the same breakdown as Litematica's Schematic Verifier: missing (red), wrong block (orange), wrong state (yellow), extra (light blue), drawn through walls. Toggled with a keybind.
• Updates in real time — place a block and its marker disappears, the progress bar moves instantly.
• Remembers your zones — zone layout and progress survive leaving a server or switching dimensions.

How to use it

1. Place a schematic with Litematica as usual.
2. Open the zones screen and split the placement into a grid — or mark a single zone by dragging with the mouse.
3. Select a zone. Only that part of the schematic is rendered and counted.
4. Build it, watch the progress bar, then move on to the next zone — manually or automatically.

Settings

Open with Ctrl + J, or from the zones screen. Everything above can be turned off individually; on top of that:

Keybinds

Only one is bound by default — the rest are up to you.

Pairs well with

Litematica Material HUD & Chest Finder — a material list HUD for the layer you're building, plus colored markers on the chests holding those blocks. Zone Focus tells you where to build; Material HUD tells you what to bring.
