Rand node¶
This documentation is for version 1.0 of Rand.
Description¶
Generate a random field of noise. The field does not resample if you change the resolution or density (you can animate the density without pixels randomly changing).
Inputs¶
Input | Description | Optional |
---|---|---|
Source | Yes |
Controls¶
Parameter / script name | Type | Default | Function |
---|---|---|---|
Extent / extent |
Choice | Default | Extent (size and offset) of the output.
Format (format): Use a pre-defined image format.
Size (size): Use a specific extent (size and offset).
Project (project): Use the project extent (size and offset).
Default (default): Use the default extent (e.g. the source clip extent, if connected).
|
Center / recenter |
Button | Centers the region of definition to the input region of definition. If there is no input, then the region of definition is centered to the project window. | |
Reformat / reformat |
Boolean | Off | Set the output format to the given extent, except if the Bottom Left or Size parameters is animated. |

Bottom Left / bottomLeft |
Double | x: 0 y: 0 | Coordinates of the bottom left corner of the size rectangle. |
Size / size |
Double | w: 1 h: 1 | Width and height of the size rectangle. |
Interactive Update / interactive |
Boolean | Off | If checked, update the parameter values during interaction with the image viewer, else update the values when pen is released. |
Frame Range / frameRange |
Integer | min: 1 max: 1 | Time domain. |
Output Components / outputComponents |
Choice | RGB | Components in the output

|
Noise / noise |
Double | 1 | How much noise to make. |
Density / density |
Double | 1 | The density from 0 to 1 of the pixels. A lower density mean fewer random pixels. |
seed / seed |
Integer | 2000 | Random seed: change this if you want different instances to have different noise. |
Static Seed / staticSeed |
Boolean | Off | When enabled, the seed is not combined with the frame number, and thus the effect is the same for all frames for a given seed number. |
