3D Model: Please Convert This Into A Fully Realized 3D Model In GLB/OBJ/GLTF Format. • **Primary Focus**: Match The Precise Geometry — Multi-layered Transparent Casing With Nested Reflective Metallic Cubes. • **Surface Qualities**: – Outer Transparent Shell With Subtle Reflections, Slight Tint. – Inner Cubes: Gold-metallic Finish With Sharp Edges And High Reflectivity. • **Lighting**: Soft Studio Lighting To Emphasize Reflections And Material Transitions. • **Composition**: Keep The Central Alignment And Cubic Symmetry. • **Mesh Detail**: Ensure Clean Topology Suitable For CAD/XR Workflows. • **Texture Output**: Provide PBR Materials — Metallic (specular/roughness) And Glass (transparency, Refraction). • **Camera**: Generate A Neutral Front/angled Perspective View. • **Export Format**: Provide Downloadable .GLB With Textures And Materials Intact. Optionally, Also Include: – A Grayscale Depth Map Or Normal Map.
