Manhattan Rebuilt Inside Unreal From Photos

⊲ Something Big Is Happening ⊳ Matt Shumer, AI entrepreneur and investor, has used AI to rebuild Manhattan and his childhood neighbourhood, together with a playable zombie survival game, in Unreal Engine and Three.js, a library that lets 3D worlds run directly in a browser rather than as a downloaded app. These builds have drawn over 15 million views on X. Here he sets out his method for building photorealistic 3D worlds with GPT-6 Astra: a five step loop moving from reference imagery through Blender asset generation, sub-agent specialisation and Three.js or Unreal Engine assembly, repeatedly tested by independent agents comparing renders against real photographs.
⊲ Pairing Unreal Engine assembly with Three.js browser builds suggests studios may soon prototype full worlds without traditional 3D artists on staff. ⊳
