# Out

Outputs areas of foreground that do not overlap with background.

## Parameter Types

Parameter Types Parameter descriptions Discussion The Out node determines its output using the alpha channels of the foreground and background inputs. The RGB component of the output is F*(1-b) and the alpha component of the output is f*(1-b). The visual effect of this node is that within the output, the node preserves the foreground values that don’t overlap with the background alpha. Below is a simple node graph that uses the Out node to blend a tile and rock texture:

Below are the two original images, the image representation of the alpha of the background, and the resulting blended texture applied to a cube:
