I've upgraded the client from Unity 4.6 to Unity 5.0. In doing so I also kicked the textures/materials up a notch and introduced lighting. I also finally made up my mind that I wasn't going to use artificial lighting in deep space. This does mean that it won't look like Star Trek (with bright white ships), but that the outsides of the ships will usually be dark (as they would in real life) when far away from any suns.

Please check out the video and let me know what you think.
