Design an isometric 3D icon that represents the concept of adding lights, textures, and materials in architectural design and 3D modeling. The icon should feature a cube or sphere at the center to symbolize a basic 3D object. Surrounding the object, incorporate light sources (like small lamps or light beams) to indicate lighting, with soft gradients and shadows highlighting the object. On the surfaces of the object, display subtle texture details like brushed metal, wood grain, or fabric patterns, indicating the application of materials. Finally, add smaller icons or symbols representing texture brushes, sliders, or paint buckets to indicate the process of adding textures. Use a modern, sleek design with a cool-toned color palette, mixing blues, whites, and metallic shades to give a professional and tech-savvy feel.
