MagicalChalk vs SchemConvert

MagicalChalk is a Minecraft mod for creating, importing, exporting and placing structures in Minecraft Java Edition 1.21.1 with NeoForge 21.1.x. It supports single-player, LAN and server play, including dedicated servers. Structure Chalk lets players mark an area by clicking two corners and save it to the server’s world storage. A selected blueprint can then be placed in-game with Magical Chalk, replacing obstacles. The mod works with .chalk, .json and .nbt files and converts .litematic, .schem and vanilla structure .nbt files. Its import manager can search files and show metadata such as dimensions, volume, block count and file size. Magic Chalk Studio provides placement, brush, line, shape, selection, paste and erase tools, with undo and redo shortcuts. A public API lets other mods register structures and associate them with biomes using JSON or Java. LuckPerms is optional; without it, most admin actions require OP level 2 by default. The interface is translated into English and French. MagicalChalk is free and MIT licensed.

SchemConvert is a free, open-source desktop tool for converting Minecraft schematic files between four formats: .nbt, .schem, .litematic, and .bp. The formats correspond to different Minecraft tools and workflows: .nbt is used by vanilla structure blocks, .schem by community programs such as WorldEdit and MCEdit, .litematic by Litematica, and .bp by Axiom for blueprints. It can process multiple schematics in one batch, and command-line conversion to .litematic is supported. The listed placement workflow is export-only, so the tool’s role is converting and exporting files rather than placing them. SchemConvert runs on Linux, macOS, and Windows desktop systems and requires Java 21 or later. The repository is published under the GPL-3.0 license. GitHub reports no published security advisories and no SECURITY.md file. The project is hosted on GitHub, where its owner describes occasional coding and contributions to ParchmentMC mappings.
