Create a game-ready 3D model of a medieval engraved goblet from the European Middle Ages (12th–15th century). The goblet is silver with detailed floral engravings and a gem-encrusted base, showing slight scratches and tarnish. Textures are PBR with 2K resolution, including diffuse, normal, metallic, and roughness maps, highlighting intricate metalwork and gem reflections. The model is posed in a neutral upright position, with a semi-realistic style balanced for detail and performance.
