# Overlay

A blend operation that multiplies dark areas and screens light areas.

## Overview

Overview 2 * F * B if F < 0.5; 1 - (1 - F)(1 - B) if F >= 0.5 Parameter Types Parameter descriptions Discussion The Overlay node has one of two effects: If F+B is less than 0.5, then the node outputs a value of 2*F*B. If F+B is greater than or equal to 0.5, then it outputs1-(1-F)(1-B), which creates the same visual effect as the Screen node. Visually the node makes dark areas of the blended texture even darker and light areas of the blended texture even lighter. Below is an example of a simple node graph that uses the Overlay node to blend two images together into a single material:

Below are two images and their resulting blended texture applied to a cube:
