Channel Shuffle

Node icon
Color

Rearranges RGBA channels by swapping, duplicating, filling with black/white, or rerouting any channel to any other.

The Channel Shuffle node applied to a source image — original (left) and result (right).
Side-by-side comparison: the original image on the left and the same image after the Channel Shuffle node on the right.

Channel Shuffle lets you reconfigure which data goes into each output channel. For each output channel (Red, Green, Blue, Alpha), you pick a source: any of the input channels, or constant Zero (black) / One (white).

Common uses include swapping channels, isolating a single channel, filling alpha with luminance data, or converting a normal map format.

Usage Tips

Section titled “Usage Tips”
  • Set all outputs to Red to convert to grayscale using only the red channel.
  • Swap Red and Blue to convert between RGB and BGR formats.
  • Set Alpha source to Zero or One to force fully transparent or fully opaque output.
