Game-ready 3D model of a broken Skyrim carriage, featuring cracked wooden wheels, a weathered and aged frame, with rusted metal fittings. The carriage should appear abandoned, with detailed wear from snow and harsh weather conditions, including broken parts like shattered glass and torn leather. The asset should be optimized for use in an open-world RPG setting, with a focus on realism and attention to texture details for the wood, metal, and fabric elements.
