Rand node

pluginIcon

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: Use a pre-defined image format.
Size: Use a specific extent (size and offset).
Project: Use the project extent (size and offset).
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.
Format / NatronParamFormatChoice Choice HD 1920x1080 The output format
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.
