One Color Ray
The One Color Ray generator creates a ray pattern based on variations of a color. You can
select the color, the degree of variance, the number of divisions represented, and rotation
of the pattern.

Parameters in the Inspector
Color Space: A pop-up menu that sets the color space. Generally, if you are working in
NTSC, use YIQ. If you are working in PAL, use YUV.
Offset: Sets the coordinates of the ray pattern’s center. Coordinates are calculated from
the center of your object, which is the coordinate origin.
You can also use the Adjust Item tool to adjust this parameter using the onscreen controls.

Editing Generators Using Onscreen Controls .
Color: Picks the base color for the one color ray.
Color Variance: Sets how much the colors differ from each other.
Divisions: Sets the number of divisions in the ray pattern.
Rotation: Sets the rotation of the whole pattern from the center point.
Sharpness: Defines the hardness of the edges of the rays. Values ranges from .25 to 1.
Waviness: Positive or negative values create waves in the rays. Values range from –10 to
10.
Frequency: When Waviness is set to any value other than 0, determines the number of
waves in the rays.
Phase: When Waviness is set to any value other than 0, defines the offset of the waves
from the start and end of the rays. (Animate this value to create interesting effects.)
Inner Cutoff: Defines a center stopping area for the generator. A value of greater than
0 creates a hole in the middle of the generator; the greater the value, the larger the hole.
Objects composited below the generator in the project appear in the cutoff areas.
