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.
