Claude Opus 5.5 Codes a 36-Second Cinematic Blender Short, Fully Open-Sourced

A developer used Claude Opus 5.5 to create a 36-second cinematic short film: with no pre-made 3D models or textures, everything—from mechanical gears and a sports car to a temple, lighting, and camera motion—was generated as Python code by Opus driving Blender, and the full project plus a companion Cook Skill have been open-sourced on GitHub. It's another reproducible example of the "pure code-generated 3D imagery" approach; what's notable isn't how polished the final film is, but that the entire production pipeline has been codified and made reusable.

Confirmed

• How it was made: using Opus 5.5 xhigh ultracode, one main prompt with minor manual tweaks; Blender 5.2 ran in headless mode with EEVEE rendering; editing, color grading, and sound mixing were all done in post via code (NumPy/FFmpeg).
• Production details: the sports car shot referenced a Three.js + Seedance video; Opus generated its own reference images for the temple and gears, designed the transitions, then Python created the objects and materials in Blender; the music uses CC0 assets.
• Retrospective and flaws: the author admits the film isn't perfect—the cloud reveal effect is "a bit like Dune"; the model originally produced better clouds, but rendering them crashed the integrated GPU (AMD Radeon 780M), so they had to be cut. The author also cleared up some outside misconceptions (the original post didn't go into detail).
• Open source: the full project is hosted on GitHub at Leonxlnx/escapement under the MIT license, including the 1080p final cut and links to the Cook Skill used; it had about 105 stars at publication. A repost added two links to the repo and the skill file.

Why it matters

• The project demonstrates a complete LLM-driven "write code to shoot film" workflow end to end: reference image generation, transition design, scene construction, and post-production mixing are all done by model-generated code, with humans only making minor adjustments.
• With the open-source repo and a reusable Cook Skill, this pipeline is not a one-off demo—other developers can download, replicate, and modify it, lowering the barrier for 3D imagery generation experiments.
• The author's honest retrospective on rendering limits (integrated GPU crashes forcing reduced effects) is also practically useful: the current bottleneck lies partly in hardware, not model capability.
