XLiquidGlassMaterial, The Hall of Supreme Harmony in the Forbidden City, entirely wrapped in Apple's Liquid Glass material. When sunlight shines, the glass surface refracts colorful lights. The glazed tiles on the roof turn into flowing golden liquid, and the auspicious beasts at the eaves seem to be dancing vividly in the liquid glass. The red palace walls become semi - transparent crimson glass, exuding a soft halo.
