mcblend vs Minecraft Bedrock Debugger

mcblend is a free, open-source Blender add-on for creating and modifying Minecraft Bedrock Edition models. It imports and exports entity and attachable models, including cubes and polymeshes. For animation, it exports keyframes and poses, and can bake animations into Minecraft format, including work using inverse kinematics and constraints. It can also turn Blender camera movement and field-of-view animation into JavaScript data for Minecraft Script API cutscenes and scripted camera playback; additional game logic is needed to apply that data to a player's camera.

The add-on arranges UV coordinates for cube faces and can create a template texture. Polymeshes use Blender's regular texturing features. It also draws on Blender's rigging and physics tools and can set up rigid bodies automatically. Installation uses a ZIP downloaded from GitHub releases and added through Blender's Add-ons preferences; the documentation instructs users to install Blender 5.2. Models must use exactly one armature, with each cube or polymesh as a separate object parented to armature bones. Polymeshes are experimental in Minecraft and may not remain supported. Updates require removing the old add-on and installing a new version.

Minecraft Bedrock Debugger is a free, open-source Visual Studio Code extension for developers building Minecraft Bedrock behavior packs and add-ons with JavaScript or TypeScript. It connects through script debugger commands, using port 19144 by default, and supports breakpoints, stepping, a Locals pane and watches. Developers can run Minecraft slash commands and keep shortcuts for favorite commands. Performance tools provide diagnostics and a script profiler that saves captures to a configured local path. Minecraft 1.21.10 or later can expose server statistics including entities, chunks, memory, tick time and network usage. Client diagnostics include FPS, memory, entity systems and CPU profiling, but require Minecraft’s “Enabled client diagnostics” creator setting. Scripts can add live diagnostics through the @minecraft/debug-utilities module. TypeScript projects can use source maps through sourceMapRoot and generatedSourceRoot. Dedicated Server debugging requires enabling inbound or outbound script-debugging settings in server.properties, which are disabled by default. Changing variable state and immediate mode are unsupported.
