alien spacecraft 3d model

Dark alien spacecraft with a flat triangular wedge silhouette, a single sharp front tip acting as the nose, a wide rear edge, and a low, solid, compact body. The craft must look like one continuous geometric mass, not a fighter jet, not bulky, not rounded, and not built with human aircraft logic. Matte black and dark gunmetal metallic hull, smooth angular surfaces, hard clean edges, subtle engraved panel lines, faint non-human mechanical details, and only a few very small cold lights. No bright glow, no colorful effects, no visible cockpit glass, no large wings, no tall structures. The top view must be unmistakably triangular, simple, oppressive, and predatory. Realistic 3D model, cinematic shading, mysterious extraterrestrial engineering, dark, intimidating, minimalistic, advanced, cold, and functional.
