The Star Field procedural texture produces a starry night pattern (figure 1).
Figure 1: The Star Field texture applied to a Diffuse materialUsed for dull, non-reflecting materials or mesh emitters.
Density - The number of stars in the field.
Falloff - Determines how quickly the edges of each star fade off.
Intensity - Specifies the brightness of the stars.
Spectral - If enabled, more distant star's color will shift towards red.
Temperature (min/max) - Used to determine (in Kelvin) the color range of the stars when Spectral mode is enabled.
UVW Transform - Positions, scales, and rotates the surface texture.
Projection - Sets how the texture projects onto the surface.
