Create a 3D model of a split-form alien. The creature has a flexible, organic body that can separate into two independent halves. Its design is biomechanical, with smooth, sinewy textures and a glowing energy core at the center. The body is segmented, allowing a clean split, with tendrils or organic cables connecting the halves before they fully separate. Its skin is a mix of metallic and organic materials, with pulsating veins of bioluminescent light running across its form.
