MagicalChalk

Players select an area in the game with the structure chalk using two clicks, then save the result as a structure. Saved structures are kept in the server's world storage, and a blueprint can be placed with a right-click of the Magical Chalk, which replaces any obstacles in the way. Structures can be imported from .chalk, .json and .nbt files, and schematics from WorldEdit (.schem) or Litematica (.litematic) are converted, as are vanilla .nbt structures.

The mod includes a builder for advanced creative mode, the Magic Chalk Studio, and a set of showcase structures such as a hub and an End fortress, which work on dedicated servers, LAN and single-player. Other mods can register their own structures through the API and bind them to existing biomes. Operator permissions govern the admin actions, and a LuckPerms setup can replace the default operator level 2 requirement. The client and server both run the mod, and the interface is translated into English and French.
