Ultra-detailed 3D model of Iron Man in his iconic red and gold armor, inspired by the Mark LXXXV suit from Avengers: Endgame. The armor features hyper-realistic metallic surfaces with PBR textures — red anodized titanium panels with subtle edge wear and scuff marks, gold-plated joints, and intricate mechanical underlayers visible in the arm, chest, and leg seams. The Arc Reactor is embedded in the chest plate, glowing with a soft blue light, with inner circuitry and illumination bloom effects. Armor segments are fully articulated: shoulder pads, elbow guards, gauntlets, knee plates, and jet boots with detailed thrusters and micro-flap mechanisms. Visible nano-tech panel lines suggest modular movement.
