3D渲染开学季校车校园交通商业照片

C4D render, ray tracing, high resolution. A classic American school bus in bright yellow gradient clay, with a long, boxy body, rounded corners, and a prominent black bumper. Small rectangular windows line the sides, and a flashing stop sign extends from the driver's side. A nostalgic, childhood-memory tilt. Warm, cheerful and morning-route lighting on pure white background.
