Starscape is a Blender add-on for adding stars to the background of a scene.
The add-on provides the following features:
Link to Blender Artist page
The controls for the addon can be found in the Properties panel under World > Starscape.
Press 'Generate Starscape' in the panel. That's it! An object called 'Starscape' is created. It is anchored to the camera and thereby appears to remain fixed in the render even when moving the camera.
At the moment there are no options. This will change in the future.
The stars are randomly generated. In order to get reproducible results, the random number generator is initialised with a seed value. If the random result is not pleasing in some way (e.g. because there are a bunch of stars too close together by chance), try changing this value.
The star density can be different depending where you are within a given galaxy. The density value of 1 is used here to represent the conditions found here near the earth. If you set the density to 2 you will see twice as many stars. Note that increasing this number is not realistic in our part of space. Also note that complexity of the scene increases with this number.
You can change the intensity of the stars using this value. At the moment, the value 1 is arbitrary. Note that the interpretation of the intensity value may change in the future to more realistically render stars with a given film exposure.
For scenes on a planet or moon the stars below the horizon are not necessary. This option reduces the amount of computing resources needed.
Attaches the starscape object to the camera such that the stars remain fixed with respect to the camera. This should always be activated because stars are usually very far away from an observer and their movement is negligible with respect to the motion of the observer. If you have a star that is very close (such as the sun), you should model it separately.
Clears the world background material and sets the color to pure black.
The following features are planned for the future:
