I didn't touch
the 3D. The agent built it.

The car jump from my reel started as a grey blockout, like the world around you. Fly through it to see how.

Tell it where the camera goes

Describe where to put the camera and how it should move. The agent places it and animates it for you. Prefer to do it by hand? You can move it yourself in the viewport too.

The scene prompt I gave the agent

Build a 3D blockout scene for a single 6 second car stunt shot. Keep all geometry simple and readable, clay grey materials only, no textures. 1. Road: straight two lane desert highway, 8 m wide, with a painted centre line and gravel shoulders. 2. Canyon: a river canyon crossing the road, 24 m wide, rocky walls dropping down to the water. 3. Drawbridge: a small rural steel bascule bridge with two leaves, each raised 20 degrees, leaving an open gap of about 5 m between the tips. Truss railings on both sides. 4. A small operator hut and a lowered barrier arm before the bridge. 5. Wooden telephone poles every 40 m with sagging wires, low rolling desert hills in the distance. 6. Hero car: a boxy early 1970s four door sedan. Truck: an old tanker truck chasing it. The car breaks through the barrier, launches off the left leaf, flies over the gap and lands on the far bank, then drives away. Add a camera that follows the whole move with smooth, natural motion.
