A comprehensive Blender BPY skill enables smaller LLMs like DeepSeek V4.1 Flash to generate higher-quality 3D models through a structured three-stage workflow (planning, building, self-review) rather than unassisted code generation. Built for Capybala, an AI agent desktop app, the skill demonstrates that models without 3D specialization can produce professional results when given proper scaffolding, though performance varies by model capability and certain domains like vehicles and human figures remain weak points.
