Swap the RGBA colour channels.
Channel Boolean
Method #
This node allows you to swaps RGBA channels of the image, useful for functional needs such as adding a solid alpha channel to a transparent image, or artistic needs such as swapping the red and blue channels for a glitch effect.
This node is also useful for extracting an individual channel from an image, such as the red channel from a texture with multiple material maps inside.
Parameters
These properties control the core behaviours of the node.
Parameter Details Blend Amount
Changes the opacity of the new effect over the original image.
These properties control which colour channels to swap.
Parameter Details Red Source
Choose which channel to replace red.
Green Source
Choose which channel to replace green.
Blue Source
Choose which channel to replace blue.
Alpha Source
Choose which channel to replace alpha.
The properties control the time at which the node is active. See Timeline for editing time segments.
Parameter Details Duration
Control the duration of the node’s time segment.
- Composition Duration : Use the length of the composition for the node’s time segment duration.
- Custom : Set a custom duration for the node’s time segment.
Node Time
The custom start and end time for the node.
Duration (Timecode)
The length of the node’s time segment (in time).
Duration (Frames)
The length of the node’s time segment (in frames).
Time Segment Enabled
Set whether the node’s time segment is enabled or not in the Timeline.
