Create a high-quality, game-ready 3D character mesh in a T-pose, inspired by Darth Vader, designed for Unreal Engine 5. The character should wear a futuristic black armored suit, feature a glossy black helmet, and a long flowing dark cape. The character must be holding a glowing red lightsaber in their right hand, in a neutral T-pose suitable for rigging and animation. Include sci-fi chest controls and detailed armor plating. Use realistic PBR textures (albedo, metallic, roughness, and normal maps). The model must be fully humanoid, with clean topology, and optimized for UE5, matching the Unreal Engine mannequin skeleton. Export format should be FBX or GLTF
