I'm very excited to announce SPACE for Unity - Space Scene Construction Kit
This is an extension to the Unity Editor that allows you to create random space scenes with a single mouse click. You can also customize filters to create the mood you want for your game. Instead of using a skybox, this extension assembles a complete scene by selecting random textures and meshes to form a background that renders behind your normal camera. This way you get unique scenes for your game and you conserve memory space in the process. You also get space particle effects, local and infinite asteroid fields, space ship prefab, demo scenes, and much more.
You can also visit the Space Unity site which contains more details, screenshots, videos, and tutorials: http://www.spaceunity.com
