Stars are randomly placed halo-like objects which appear in the background.
The Stars settings are on the right-hand side of the
Mist Stars Physics Panel (Figure 13.8, “Star buttons”).
When creating stars, you need to understand a few important concepts:
StarDist: is the average
distance between stars. Stars are intrinsically a 3D feature, they
are placed in space, not on the image!
MinDist: Is the minimum distance
from the camera at which stars are placed. This should be greater than the distance from
the camera to the furthest object in your scene, unless
you want to risk having stars in front of your
Size: NumButton defines the actual size of the star halo.
It is better to keep it much smaller than the proposed default, to keep the material
smaller than pixel-size and have pin-point stars. Much more realistic.
Colnoise: NumButton adds a random hue to the otherwise
plain white stars. It is usually a good idea to add a little ColNoise.
