Agents infer LEGO mechanisms and animate them in Blender

LDraw Mecha lets an AI coding agent turn a LEGO model in LDraw format into an animated Blender file. The agent reads the .mpd source, splits it into submodels, finds the mechanisms (steering, gearboxes, cranes), plans how they move, then writes the Blender Python that rigs and animates them. Setup is tested on macOS only; Linux and Windows (WSL) are untested. No physics, and large models take long. Code AGPL-3.0, docs CC BY-SA 4.0.

    The LDraw library holds decades of LEGO models as plain text files, but they never move. LDraw Mecha has an agent read that source like code, work out which parts form a mechanism, and rig it in Blender. The author is upfront that big models are slow and agents can still get lost, and the Show HN reached 31 points.
