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.

Note: This plug-in is located in: Built Ins -> Shader -> PixelFX
