3D Model: Create A Highly Realistic 3D Model Of A Heavy-duty Concrete Mixer Truck. The Truck Must Feature A Large Cylindrical Mixing Drum Mounted On The Back, Similar To Industrial Cement Trucks. Use A Clean And Polished Appearance With Realistic Proportions, High-fidelity Geometry, And Fine Detailing. The Cab Should Be Modern And Sturdy, With Dual Side Mirrors, Visible Steps For Cabin Access, Exhaust Pipes, Rugged Tires, And A Reinforced Front Bumper. The Vehicle Should Have Six Wheels (three Axles) With Detailed Hubcaps And Tire Treads. The Mixing Drum Should Be Prominently Large And Positioned At The Rear, With Visible Support Structures And Rotation Axis Components. Apply Realistic Metal And Rubber Materials Throughout The Truck: Shiny Chrome For Exhaust And Mirrors, Matte Black For The Wheels And Undercarriage, And A Painted Yellow-orange Body For The Cabin And Drum. Add Subtle Wear Details Like Dirt Buildup On The Tires And Light Scratches Or Smudges On The Body For Realism. Render In A
