The Grain node
Grain Node Introduction
The Grain node offers an older film grain emulation than the more modern and accurate Film
Grain node. The Grain node is still provided to allow older compositions to load and render, but
in almost every case, it is better to use the Film Grain node.
Input
There are two Inputs on the Grain node; one for the 2D image and one for the effects mask.
–
Input: The orange input is used for the primary 2D image that gets the grain applied.
–
Effect Mask: The blue input is for a mask shape created by polylines, basic primitive
shapes, paint strokes, or bitmaps from other tools. Connecting a mask to this input
limits the grain to be within the pixels of the mask. An effects mask is applied to the
tool after the tool is processed.
