pxNoise is a white noise generator. It deploys the same turbulence as seen in other PixelFX plug-ins. Similarly to the pxGradient, it generates its own texture if applied to a container without an image, or blends with the existing texture if the container has an image applied.

Adjust the following parameters as required to achieve the required effect:

• Size

• Amplitude: Intensity/contrast of grains

• Color

• Speed: Turbulence noise

• Stretch: Stretches the grain to achieve a rain look of noise

• Stretch Angle

• Movement: Transforms the generation of noise

• Transform as Texture

  • On: Conforms to texture coordinates.

  • Off: Ignores texture coordinates and behave as stencil mapping.

• Apply to: RGB, RGBA, Alpha: Determines the channels in which the noise is generated.
