pxNoise
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: Conform to texture coordinates. Off: Ignore 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
