The decorative mirror model Relief Mirror by HKliving features a frame made of individual relief segments in a pyramidal/faceted shape, where each facet reflects at its own angle, creating the effect of a "broken" mirror pattern. Unlike a flat imitation, the relief is executed with real geometry — the volume and depth of the facets are perceivable from any angle, not just frontally.

Materials:
— The texture of the aged mirror is well-developed — foxing spots, slight cloudiness, and patina streaks on the glass surface, rather than a clean mirror shader
— Black frame around the perimeter
— High-resolution textures

Ready to use in the scene — realistically reflects the surroundings due to the volumetric geometry of the facets, not a flat texture.
