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.
