Noise Tool

 
 
 

The Noise generating tool lets you add realism to computer-generated images, or to simulate or match film grain. The generator creates an image of random pixels. The Noise generating tool is comprised of three sets of color channel value fields that allows you to generate a multi-color image based on RGBA values. One set of values is for generating the fill color, and two sets are for generating start and end color values. You can also adjust the level and seed (the method used to generate the noise).

NoteThe following procedure assumes that you have a Schematic and a Player view open.

To create an image using the Noise tool:

  1. Drag the Noise tool from the Tools tab to the dependency graph in the Schematic view and attach it to the Output node.
  2. Apply image properties—see Setting Image Generation Properties and Formats.
  3. Adjust the color values in the Fill, Start, and End fields.
  4. Adjust the noise seed.
NoteYou can also type values into the value fields and press Enter.
NoteThe Noise tool's Fill, Start, End, and associated Seed parameters are animatable by setting keyframes or using expressions—see Setting Keys Manually and Validating and Applying the Expression String.
