公开提示词
A futuristic sports car remains perfectly stationary in a dark premium studio while its exterior material transforms in three seamless stages: brushed titanium, transparent smoked glass, then glossy deep-red ceramic. Slow front-quarter camera orbit, narrow white light strips traveling across the body, controlled reflections, luxury automotive commercial, subtle mechanical sound design. Preserve the exact car silhouette, wheels, panel gaps, windows, badge position, camera path, and studio geometry throughout; only the body material changes, with no melting, warping, extra parts, or cuts.
