GPT-6 Astra Rebuilds a Real 3D Scan into a Blender Scene from Scratch
On September 5, creator Bilawal Sidhu published a series of hands-on demos showing GPT-6's Astra model rebuilding an old photogrammetry scan of his parents' living room into a complete Blender scene from scratch. No existing assets were downloaded: textures were extracted from the user's scan, the model wrote its own procedural shaders, and it handled modeling, texturing, lighting and animation, ultimately rendering a 30-second flythrough. Sidhu shared the full prompt and called the results quite good.
Confirmed
- The demo was posted by Bilawal Sidhu and amplified by accounts like jnack, joking that "KBS Cribs is back"
- Zero downloaded assets: textures came from the user's scan; shaders were procedurally written by the model
- Workflow details: two loops of roughly 45 minutes each, with a critic agent evaluating output quality against multi-view images of the input 3D scan; Sidhu also planned to let the task run overnight
- Sidhu published the full prompt
Why it matters
- Converting messy real-world 3D scans into clean, editable procedural scenes like a human artist would has long been a high-bar problem; Sidhu believes Astra has crossed that gap
- A single model completed the full modeling-to-animation pipeline in 45-minute loops; if reproducible, this could dramatically lower the barrier to 3D scene creation
