concrete mixer truck 3d model

A realistic 3D model of a concrete mixer truck (cement truck) for a construction site. The truck has a large rotating drum with spiral blades at the back, painted in bright orange and white. The cab is detailed with windows, headlights, grille, and mirrors. The chassis includes visible wheels with rims, a fuel tank, exhaust pipe, and a ladder leading to the back of the drum. The drum has a metal texture with some wear and rust spots. The model should be game-ready, with medium polygon count (suitable for VR), PBR textures (diffuse, metallic, roughness, normal maps). CRITICAL: All polygons must be flat and hard-edged, no smooth shading or sculpted surfaces, clear and sharp geometry with distinct faces, hard surface modeling style, no subdivision smoothing, each polygon face should be clearly visible, industrial precision look. No background, isolated object. Style: realistic, industrial, hard surface.
