Generate a realistic 3D model of a male factory worker. He is wearing a white lab coat with long sleeves, black pants, and black shoes. His face is partially covered by a white surgical mask, and he has a blue disposable hairnet on his head. The character is standing in a neutral pose with arms relaxed at the sides. The model should have detailed textures, including fabric folds on the coat, shadows, and realistic lighting. The environment should resemble a clean industrial or factory setting.
