Create a highly detailed and realistic 3D model of an old, abandoned treasure chest. The chest should be weathered, with rusted metal hinges, faded engravings, and wooden planks that show signs of rot and wear. The lock should be partially broken, hanging loosely as if it hasn't been opened in centuries. Moss and vines should grow around the base, and small cobwebs should cling to the corners, giving it an abandoned, forgotten look.
