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 the rotation of the pattern.
Adjust this generator using the controls in the Generator 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: Value sliders that set 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 modify this parameter with onscreen controls. For more information, see Modify or animate a generator.)
Color: Color controls that pick the base color.
Color Variance: A slider that sets how much the colors differ from each other.
Divisions: A slider that sets the number of divisions in the ray pattern.
Rotation: A dial that sets the rotation of the whole pattern from the center point.
Sharpness: A slider that defines the hardness of the edges of the rays. Values range from .25 to 1.
Waviness: A slider that warps the rays into waves. Values range from –10 to 10.
Frequency: A slider that determines the number of waves in the rays when Waviness is set to any value other than 0.
Phase: A slider that defines the offset of the waves from the start and end of the rays when Waviness is set to any value other than 0. (Animate this value to create interesting effects.)
Inner Cutoff: A slider that defines a center stopping area for the generator. A value 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.
Outer Cutoff: A slider that defines an outer stopping area for the generator. The lower the value, the more the outer edges of the generator are cut off. Objects composited below the generator in the project appear in the cutoff areas.
Publish OSC: A checkbox that, when selected, ensures that if this generator is sent to Final Cut Pro X as part of a template, the onscreen controls are accessible in Final Cut Pro. For more information about publishing onscreen controls and other parameters, see Final Cut Pro templates overview.
