GPT-6 Astra builds a full hospital corridor in Blender via MCP in ~45 minutes

An art director (not a 3D artist) used GPT-6 Astra with Blender MCP to build a complete 35m game-ready hospital corridor entirely from text prompts — architecture, modular door variants, patient rooms, props (beds, IV stands, wheelchairs), a nurse station, lighting, and a cinematic flythrough — in about 45 minutes, with no manual modeling and no external assets.
The workflow ran in four approval-gated stages:
- Blockout: architecture only, organized collections, cinematic camera setup;
- Dressing: reusable door panels, deliberate prop placement across foreground/midground/background, environmental storytelling (loose papers, displaced ceiling tile), reference-matched lighting, preview render;
- Camera animation: an 8-second eased push-in with subtle handheld sway, geometry untouched;
- Relighting: AgX color management, darker foreground pools, warm light from patient rooms, subtle volumetric haze.
The key lesson: split the job into stages and pause for human approval between each, instead of letting the model one-shot the whole scene. The author offered to write a full setup tutorial.
