His Blender agent built and animated a spaceship, then caught its own thrusters firing into the ship and rebuilt them

A man built a chat copilot inside Blender in a day, at a total cost of $7.18, then gave it 5 sentences. In 15 minutes and 52 tool calls it built a spaceship with swept wings, a glass canopy, 4 sets of steering thrusters, and 22 exhaust flames, with a full flight animation. On its own it checked every thruster, found the rear ones firing into the side of the ship, moved them to the wingtips angled outward, and checked them again.

How it works

  1. He builds a chat panel inside Blender that runs model written Python against his open scene
  2. He gives it 5 plain sentences
  3. The agent builds the ship, adds steering thrusters, and animates the flight
  4. It checks its own thrusters without being asked
  5. It finds the rear thrusters firing into the ship, rebuilds them at the wingtips, and rechecks

Why it’s worth knowing

Nobody asked for the safety check. The agent spotted that its own thrusters were firing into the ship it had just built and fixed the layout itself.
