Difference

Outputs the distance between foreground and background values.

Overview

abs(B - F)

Parameter Types

Parameter descriptions

Foreground: The foreground input. Represented by F in the mathmatical equation.
Background: The background input. Represented by B in the mathmatical equation.
Mix: The weight of the blend effect. The higher the Mix, the greater the intensity of the blend operation, and the more the effect is visually apparent. The default value is 1. Values outside of the range 0-1 produce an undefined effect outside of the node’s intended function.

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:
