Generate a detailed 3D model of a gold ring. The model should be low to mid-poly (500-5000 polygons) with clean topology for animation and optimized for real-time use. Include properly UV-mapped textures (diffuse, normal, roughness) and apply PBR material properties. Ensure the asset is styled according to sonic the hedgehog and includes small details like wear or weathering where appropriate. If applicable, add a basic rig for animation and optimize the model for performance.
