2D Processing Nodes, Color Coded by Type
These encompass most 2D processing and compositing operations in Fusion, all of which
process RGBA channels and pass along auxiliary channels. These include:
 Orange Blur nodes
 Olive Color Adjustment nodes (Color Adjustment nodes additionally
concatenate with one another.)
 Pink Paint nodes
 Dark orange Tracking nodes
 Tan Transform node (Transform nodes additionally concatenate with one another.)
 Teal VR nodes
 Dark brown Warp nodes
 Gray nodes, which includes Compositing nodes as well as many other types.
Additionally, some 2D nodes such as Fog and Depth Blur (in the Deep Pixel category) accept
and use auxiliary channels such as Z-Depth to create different perspective effects in 2D.
TIP: Two 2D nodes that specifically don’t process alpha channel data are the Color
Corrector node and the Gamut node. The Color Correction node lets you color correct
a foreground layer to match a background layer without affecting an alpha channel.
The Gamut node lets you perform color space conversions to RGB data from one
gamut to another without affecting the alpha channel.
Purple Particle System Nodes
These are nodes that connect to create different particle systems, and they’re incompatible
with other kinds of nodes until you add a pRender node that outputs 2D RGBA and auxiliary
data that can be composited with other 2D nodes and operations.
Dark Blue 3D Nodes
These are 3D operations that generate and manipulate 3D data (including auxiliary channels)
and are incompatible with other kinds of nodes until processed via a Renderer 3D node, which
then outputs RGBA and auxiliary data.
Brown Mask Nodes
Masks output single-channel images that can only be connected to one another (to combine
masks) or to specified Mask inputs. Masks are useful for defining transparency (Alpha masks),
defining which parts of an image should be cropped out (Garbage masks), or defining which
parts of an image should be affected by a particular node operation (Effects masks).
