Noise

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.

Parameters

Transform

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.

Parameter	Details
Position X	Move along the local x-axis.
Position Y	Move along the local y-axis.
Position Z	Move along the local z-axis.
Rotation Heading	Rotate around the local y-axis.
Rotation Pitch	Rotate around the local x-axis.
Rotation Bank	Rotate around the local z-axis.
Scale X	Scale along the local x-axis.
Scale Y	Scale along the local y-axis.
Scale Z	Scale along the local z-axis.

Attributes

Parameter	Details
Active	Enables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.
Preview In Viewport	Preview the effect blended with alpha in the viewport.
Preview RGB In Viewport	Preview the colour values in the viewport.
Preview Alpha In Viewport	Preview the alpha values in the viewport.
Width	The resolution of the effect along its width.
Height	The resolution of the effect along its height.
Update Time Mode	How 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.
Intensity	How strong the generated noise is.
Amount	How much noise is generated per pixel.
Scale	Scale the size of the generated fractal noise.
Animation Rate	The speed at which the fractal noise is animated.
Attack	How quickly a random point reaches its peak.
Decay	How quickly a random point decays.
RGB Noise	Toggle whether the noise is randomised colour, or randomised black and white..
Mode	Choose 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.

Rendering

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

Parameter	Details
Colour	Change the colour of the generated image.
Blend Amount	The amount the generator is blended with the output.
Blend Mode	Choose 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.
