# Difference

Outputs the distance between foreground and background values.

## Overview

Overview abs(B - F) Parameter Types Parameter descriptions Discussion The Difference node subtracts two inputs and takes the absolute value of the result, represented by the equation abs(B - F). It uses the Mix input to determine the weight of the foreground in the blend. Higher values closer to 1 output a more intense difference, while lower values closer to 0 dim the effect. Below is an example of a node graph that uses the difference node to blend two images together into a single material:

Below are two images and the resulting blended texture applied to a cube.
