What it is not

  • Not a world save and not a datapack.
  • Not Bedrock .mcstructure.
  • Not Sponge .schem — that is a different container.

How you use it

Drop it in schematics, press M, load, place the hologram. Full click path: how to import a litematic. The mod then owns the material list.

How this generator writes one

The compiler fills a voxel grid, then encodes Litematica version 6 with Java 1.21-era block ids. You can also generate a litematic from text without reading NBT.

FAQ

What is a litematic file?

A .litematic is Litematica’s schematic format (gzip NBT, currently version 6). It stores a build so the Fabric mod can project a hologram and a material list. It is not a Minecraft world.

Can WorldEdit open a .litematic?

Not as a native paste. Use the .schem from the same generate, or a converter. This site writes both so you do not need a converter. WorldEdit page.
