Ldraw Mecha

Ldraw Mecha: Agent tooling for generative LEGO mechanisms animations in Blender.

Ldraw Mecha is agent tooling designed to create generative LEGO mechanism animations in Blender. Users provide an LDraw LEGO model source code file, and an AI agent reverse-engineers the mechanics, plans component interactions, and generates Python scripts for Blender. The system creates the required rigs and animates the mechanical components based on the plan. It uses annotated glTF files to bridge source code submodels with 3D model nodes inside Blender. The project requires Python 3.12 and sets up dependencies locally within the repository.
