Schematics can be uploaded by Architects and above, who have the necessary permissions to use the /schematic upload command. This command generates a 6-digit code which may be entered in the above field to upload the schematic.

The following schematic types are supported (according to file extension): .schem (1.13+), .schematic (up to 1.12) and .litematic, used by Litematica.

The schematic preview feature lets you render schematics in your browser entirely using JavaScript. It uses nbt.js to parse the schematic and converts block models from a resource pack into three.js meshes before assembling them into an interactive scene.
