Blender's full Python API beats MCP: Simon Willison drives it with coding agents
steren · x · 2026-09-06
Simon Willison published a TIL on using Blender with coding agents on macOS: no MCP needed — just invoke the installed app with --background --python scene.py. Using GPT-6 Astra (Medium) in Codex mode, he iterated three prompts to build a pelican-riding-a-bicycle scene (2-6 min per iteration), producing .blend files, Python scripts, and rendered movies via ffmpeg. He then used Codex's skill-creating skill to save the workflow as a reusable Markdown skill. steren notes Blender has exposed all features via Python API for years — evidence that "CLI is all you need".
