Create a game-ready 3D model of a medieval wizard avatar from the European Middle Ages (12th–15th century), optimized for GameGuru to be exported as a standalone game. The wizard is an elderly male with a long white beard, wrinkled face, and bald head under a pointed hat. He wears a long ornate robe with mystical runes and a wide belt. Textures are PBR with 2K resolution, including diffuse, normal, metallic, and roughness maps, showing rich fabric with subtle embroidery and wear. The model is posed in a neutral T-pose for rigging compatibility in GameGuru, with a semi-realistic style balanced for detail and performance.
