Generates an image of random noise.



Method #

This node generates random noise pattern per pixel.

This node can be connected to any node which accepts an image input.


These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.

Position XMove along the local x-axis.
Position YMove along the local y-axis.
Position ZMove along the local z-axis.
Rotation HeadingRotate around the local y-axis.
Rotation PitchRotate around the local x-axis.
Rotation BankRotate around the local z-axis.
Scale XScale along the local x-axis.
Scale YScale along the local y-axis.
Scale ZScale along the local z-axis.
ActiveEnables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.

WidthThe resolution of the effect along its width.
HeightThe resolution of the effect along its height.
Update Time ModeHow the generator updates with relation to the timecode.
  • Locked To Timecode : The generator animations are locked to the timecode and the same time will always yield the same result.
  • Running / Loopable : The generator animations are disconnected from the timecode and will loop seamlessly at the end of the layer.
Static Image (Process Only Once)Only process the image once, making a more efficient scene. Animated Post-FX nodes will not function with this enabled.
IntensityHow strong the generated noise is.
AmountHow much noise is generated per pixel.
ScaleScale the size of the generated fractal noise.
Animation RateThe speed at which the fractal noise is animated.
AttackHow quickly a random point reaches its peak.
DecayHow quickly a random point decays.
RGB NoiseToggle whether the noise is randomised colour, or randomised black and white..
ModeChoose different kinds of noise.
  • Point : The noise generates random points of differing brightness for each frame.
  • Lines : The noise generates parallel lines of differing brightness.
  • Time Filtered Points : The noise is generated through random points at random times, allowing for the noise to be animated smoothly.

These properties control how the generators are coloured and blended with other images.

ColourChange the colour of the generated image.
Blend AmountThe amount the generator is blended with the output.
Blend ModeChoose how the image blends with the scene. See Blend Modes for details.
  • Solid : The generator is solid, with a filled alpha channel.
  • Blend : The generator RGBA values have matching alpha channels.
  • Pre-Mul Blend : The RGB values are solid white, and the generator colours are stored in the alpha channel alpha. Usually gives the best results for colour blending.
