piston assembly 3d model

Create a photorealistic 3D model of an internal combustion engine piston assembly. The model should include: Piston: Aluminum alloy appearance with realistic machining marks and subtle carbon discoloration on the crown. Piston rings: Three clearly defined rings (top compression ring, second compression ring, and oil control ring) with accurate metallic textures. Rings should be seated in the grooves of the piston. Wrist pin (gudgeon pin): Cylindrical steel pin passing through the piston, connecting it to the small end of the connecting rod. Connecting rod: Steel forged rod extending downward from the piston, with realistic surface finish, visible machining lines, and a solid big end ready for crankshaft connection. Scale and proportion: Automotive piston scale (not oversized or stylized). The model should be dimensionally accurate and suitable for educational use. Style: Photo-accurate, high detail, metallic reflections, realistic lighting, and fine machining details. Avoid carto
