Motion 5 - Noise

background image


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.

Parameters in the Inspector

Random Seed:

Because each seed value creates a different noise image, 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.

HUD Controls
The HUD contains the following control: Random Seed.
