THE SHADERS • 917
If you project the Stareld shader with spherical projection onto a Sky object,
the stars will accumulate at the north and south poles of the sky. To avoid this,
use Cubic projection.
Stars
This shader creates a star-lled wallpaper. Color 1 is the color of the wallpaper. Color 2 is the color of
the stars. Streaks is the number of star tips or points. Inner Radius and Outer Radius determine the
dimension of each star, given as a percentage of a UV unit. Density is the average number of stars
per UV unit.
You may nd it helpful to think of the preview as an element that is one UV unit in each direction.
