Noise
Generates an image of random noise.
Noise
Method #
This node generates random noise pattern per pixel.
This node can be connected to any node which accepts an image input.
Parameters
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.
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.
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.
