ice block 3d model

Thick solid ice frame structure with a large circular cutout in the center and four rectangular cutouts on the sides, exact geometry and proportions matching the reference. Material: translucent frozen ice, layered ice volume, visible internal cracks, trapped air bubbles, frosty surface buildup. Details: sharp icicles and stalactites hanging from top and bottom edges, rough frozen edges, realistic chipped ice corners. Shading: physically based ice material with subsurface scattering, cold blue-white color tone. Lighting: cinematic rim lighting for silhouette clarity, studio lighting only. Background: pure black, no fog, no smoke, no mist, no particles. Style: ultra-realistic, clean, production-ready 3D asset
