What MagicalChalk is

MagicalChalk is a Minecraft mod for creating, importing, exporting, converting, and placing structures. It supports Minecraft Java Edition 1.21.1 with NeoForge 21.1.x in single-player, LAN, server, and dedicated-server environments. Players select an area by clicking two corners with Structure Chalk, save it to server world storage, and place a blueprint with a right-click; placement replaces obstacles. The mod handles .chalk, .json, and .nbt files and converts Litematica .litematic, WorldEdit or Sponge .schem, and vanilla structure .nbt files. Its import manager searches files and shows dimensions, volume, block count, and file size. Magic Chalk Studio includes placement, brush, line, shape, selection, paste, and erase tools with undo and redo shortcuts. A public API lets other mods register structures and bind them to biomes using JSON or Java. MagicalChalk is free, MIT licensed, and translated into English and French.
