•
Brightness: A slider that sets the brightness of the sheet.
•
Color: Color controls that pick the color of the membrane. Click the disclosure triangle to
display Red, Green, and Blue sliders for more precise color selection.
Noise
The Noise generator creates a random, colored static pattern. To make animated noise, you can
keyframe the Random Seed parameter in the Noise HUD or Inspector. When filters are applied
to an animated Noise generator, you can create unique textures. In the second image below,
the Stripes distortion filter is applied to an animated Noise generator to create a vibrant, electric
light-type texture.
Default Noise generator Modified generator with applied Stripes filter
Parameters in the Inspector
•
Random Seed: A slider that sets a different noise value. Modifying this value over time yields
a constantly changing noise pattern. The easiest way to see and use the Random Seed
parameter is to add a Ramp behavior to it (in the Parameter behavior category), then ramp
from a very small random seed value to a very large random seed value over time.
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 the 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.
