飞船穿越科幻城市峡谷：从Blender灰模到电影镜头

Build a short cinematic previs in Blender, driven by Python scripts. Block out a narrow futuristic city canyon in plain gray geometry: tall slab towers on both sides, a road below, overhead bridges that cross the gap, and a small twin-engine spaceship with swept wings. Animate the ship flying forward through the canyon while a chase camera follows it with slight banking and shake. Keep everything in a neutral gray material with simple lighting so the layout, scale and camera timing read clearly. Render a roughly ten second clip at 16:9 and also export the gray frames so they can serve as a structural guide for a later stylisation or video-generation pass. Done means the ship, buildings and camera path are readable, the motion is smooth, and the blockout can be reused as a base for a photoreal sequence.
