The background input (left), foreground input (middle), and output (right) of a Blend node with Overlay blend mode.

Description

The Blend node allows you to perform a blend between two texture inputs using one of the available blend modes. For a full list of blend modes available in this node and what each of them does, see the Blend modes reference.

The node blends the content of its Foreground input on top of its Background input. You can constrain the blend effect to a specific area by using an optional grayscale Mask input.

The output texture of this node always inherits properties from the Foreground input. Texture properties include channels, bit depth, and resolution.

The Opacity property controls the visibility/influence of the Foreground input in the result.

Usage

To blend two textures using the Blend node, follow these steps:

Ensure that the textures you want to blend are already in your Node Graph.
Create a new Blend node on the graph. It can be found under the Composition category in the Node Library.
Connect the texture you wish to use as the Foreground into the corresponding input port, and the other texture into the Background port.
(Optional) Connect a grayscale mask into the Mask input port if you wish to constrain the blend effect to a specific area. In this mask, white represents areas of the texture where you want blending to occur. You can create this mask using the Mask Paint node, the Gradient node, or from a custom imported asset.
View the blending results by bringing the Blend node into the 2D and/or 3D Viewports.

Ports

Input Name	Input Type	Description
Foreground	Bitmap	The texture you wish to blend on the Foreground layer.
Background	Bitmap	The texture you wish to blend on the Background layer.
(Optional) Mask	Bitmap (Mask)	An optional grayscale mask, where white indicates the areas of the input texture to which you want to constrain the blending effect.

Output Type	Description
Bitmap	The texture that the Blend node produces by combining the two inputs.

Properties

Property/Setting	Description
Blend Mode	Choose the mode with which to blend the two texture inputs. For more details on each of the blend modes available, see the Blend modes reference.
Opacity	The overall visibility/influence of the Foreground texture over the Background, as a value between 0 and 100 percent. The way in which the Foreground influences the Background depends on the Blend Mode you chose.
