Blend
Combines two images using a specified blending mode and an optional mask.
It is the most useful node of all Atomic nodes, almost any Graph you build in Substance 3D Designer will make use of this node.
Its functionality is similar to having two layers above one another in Substance 3D Painter or Photoshop, that blend together by the blending mode you set on the top layer.
TIP
Learn about the blending modes available in the Blend node in this dedicated page.
Parameters
Opacity Float
Opacity of the Foreground layer blending into the Background. It works independent to the Opacity input and acts as an additional multiplier to it.
Blending mode Integer Static
Sets the blending operation to be used. See the dedicated page about blending modes.
Alpha blending Integer Static
Determines blending behavior when color inputs have Alpha channels:
- Use source alpha
- Ignore alpha
- Straight alpha blending
- Premultiplied alpha blending
Cropping area Float4 Static
Allow for setting a custom cropping region that behaves like an additional Opacity mask. Any area cropped shows only the background.
Input connectors
Foreground Grayscale/Color
Top or foreground layer of the Blend operation.
Background Grayscale/Color PRIMARY
Bottom or background layer of the blend operation.
Opacity Grayscale
Optional Alpha mask input.
IMPORTANT
Blend nodes have dynamic inputs that switch between Grayscale and Color depending on your connections. A Blend Node can only blend two inputs of the same type.
Connecting a Color and Grayscale input to the Foreground and Background will result in a dashed red connection line, signifying a calculation error.
This is the number one reason new users run into problems with Color vs Grayscale connections: make sure both connections are of the same type!
Output connectors
Output Grayscale/Color
