Forgematica is the Forge port of Litematica — a building-blueprint mod. Load a .litematic schematic file and it projects a translucent ghost hologram of the build into the world, so you can copy it block by block. It comes with a material list, a verifier that checks your work, and area-selection tools for making your own schematics.

Client-side only

Forgematica runs entirely on your own client — it just draws a hologram and guides you, and the server never sees it. You only need it in your client, and the pack handles the rest automatically.

How you'll use it

Press M to open the main menu, then load a .litematic file.
Place it in the world to create a placement — the ghost hologram appears where you put it.
Build by copying the hologram block by block.
Open the Material List (M, then L) to see what materials you still need.
Check your work with the Verifier (M, then V) — it marks each block as correct, missing or wrong.

What it gives you

Feature	What it does
Hologram	Projects a ghost-block preview of any schematic, aligned to wherever you place it.
Layer rendering	Show one floor at a time (`Page Up` / `Page Down`) so the hologram doesn't hide everything.
Material List	Counts exactly how many of each block the build needs, and how many you're missing.
Verifier	Compares your build against the schematic and highlights every mistake.
Easy Place	Optional mode that places the correct block, in the right orientation, with a single click.
Make your own	Select an area and save it as a `.litematic` to reuse anywhere.

Survival vs creative

In survival you'll mostly use the hologram, material list and verifier to build by hand (plus Easy Place). The mass paste/fill/move tools are creative-only.
