It's been longer than three years since I made the original alien skimmer model but I figured it needed an update.  This is a more modular version, with different weaponry and attachments that can be swapped out.  It also has baked and packed (if a bit crude) diffuse textures for each part.  The materials also have specularity and mirror reflection but those aren't baked into the textures.  The main hull has 582 triangles and the accessories obviously add to that.  Available so far are a pair of thrusters (286 tris each), heavy cannons (190 each), heavy missile launchers (200 for each missile, 79 for each rack), booster engines (206 each), a sensor array (402 for the whole thing), light guns (88 each), and mini-rocket pods (84 per rocket, 46 for each pod, 9 rockets per pod).
