Channel Boolean
Updated: 9 Sep 2025
Mix the colour channels in a shading system.
Channel Boolean
Method #
This node allows you to swap RGBA channels in a shading system. This can be useful for functional needs, such as adding a solid alpha channel to a transparent surface, or artistic needs such as swapping the red and blue channels for a glitch effect.
Parameters
Control which channels are swapped in the shader.
Parameter Details Red Source
Choose which channel to replace Red.
- Red : Replace the source channel with Red.
- Green : Replace the source channel with Green.
- Blue : Replace the source channel with Blue.
- Luminance : Replace the source channel with a Luminance value.
- One : Replace the source channel with a value of One.
- Zero : Replace the source channel with a value of Zero.
Green Source
Choose which channel to replace Green.
- Red : Red : Replace the source channel with Red.
- Green : Replace the source channel with Green.
- Blue : Replace the source channel with Blue.
- Luminance : Replace the source channel with a Luminance value.
- One : Replace the source channel with a value of One.
- Zero : Replace the source channel with a value of Zero.
Blue Source
Choose which channel to replace Blue.
- Red : Red : Replace the source channel with Red.
- Green : Replace the source channel with Green.
- Blue : Replace the source channel with Blue.
- Luminance : Replace the source channel with a Luminance value.
- One : Replace the source channel with a value of One.
- Zero : Replace the source channel with a value of Zero.
These properties control the core behaviours of the node.
Parameter Details Preview In Viewport
Passes this node’s output to the destination material as a colour channel, so it can be previewed more easily.
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.
Inputs
