sci-fi energy ring 3d model

A detailed 3D model of a cyberpunk mechanical halo, floating style. The central feature is a large, glowing red robotic eye lens embedded in the front of a thick, worn metal ring structure. Arranged symmetrically around the ring are multiple smaller mechanical camera turrets and sensor pods with glowing blue and green lenses. Complex wiring and conduits are woven around and partly inside the ring. The texture is industrial, heavily oxidized metal with rust streaks, scratches, and grime. Emissive textures for all lenses and small indicator lights. Sci-fi surveillance device, hard surface modeling style.
