运动鞋材质变形转换

Ultra-realistic cinematic video, 15s, 24fps. A single sneaker sits on a clean infinite white surface, rotating slowly 360°. The sneaker's silhouette and shape never change - only its material and texture morph continuously. CAMERA: Slow elegant orbit around the sneaker, smooth dolly push-ins to highlight texture detail, occasional extreme close-up on sole, laces, and toe box. CORE ACTION: The sneaker rotates steadily. Material transformation flows across its surface like liquid - one texture dissolving seamlessly into the next. MATERIAL CYCLE (continuous, no hard cuts): polished mirror chrome brushed gunmetal cracked volcanic rock smooth river stone raw unfinished concrete warm reclaimed wood grain translucent frosted glass liquid mercury surface woven carbon fiber rough terracotta clay hammered copper iridescent mother-of-pearl deep obsidian matte black ivory bone texture corroded oxidized bronze TRANSITIONS: Each material bleeds into the next - no snapping, no flicker. Smooth flowing morph like the surface is alive. LIGHTING: Studio three-point lighting that reacts to each material - metallic = sharp specular highlights, wood = warm diffused glow, glass = caustic light scatter. CRITICAL: Sneaker shape, proportions, and lace structure stay perfectly identical throughout. Only surface material changes. No text, no logos, no background elements with seedance in pixverse
