Set Channels

The Set Channels effect copies channels from other layers to the red, green, blue, and alpha channels of the current layer. For example, you can take the luminance of one layer and put it into the color channel of the selected layer. All source layers are centered in the current layer. With Best quality selected, any stretched layers are anti-aliased.

Use Stretch Layers to Fit to resize all other layers to the size of the layer to which Set Channels is being applied.
