The Blend node blends or mix together two separate inputs with a user-defined Blend Mode and an optional Opacity mask.It is the most useful node in all of Substance Designer; almost any Graph you build will make use of this node.
It's functionality is similar to having two layers above on another in Substance Painter or Photoshop, that blend together by the blending mode you set on the top layer.
- Foreground: Grayscale Input / Color Input
Top or foreground layer of the Blend operation
- Background: Grayscale Input / Color Input
Bottom or background layer of the blend operation.
- Opacity: Grayscale Input
Optional Alpha mask input.
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!
- Opacity: 0-1
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: Copy, Add, Subtract, Multiply, Add Sub, Max, Min, Switch, Divide, Overlay, Screen, Soft Light
Sets the blending operation to be used.
- Alpha Blending: Use Source Alpha, Ignore Alpha, Straight Alpha Blending, Premultiplied Alpha Blending
Determines blending behaviour when color inputs have Alpha channels.
- Cropping Area: Left/Right/Bottom/Top
Allow for setting a custom cropping region that behaves like an additional Opacity mask. Any area cropped shows only the background.
