Updated: 2 Sep 2025
Mix the colour channels in a shading system.
Channel Boolean
Method #
This node allows you to swap RGBA channels in a shading node system. This is 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.
Shading nodes are applied to material texture channels to generate textures procedurally while rendering.
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.
