Blend node
|
||
|
|
~~~~~~~~~~
|
||
|
|
|
||
|
|
The blend node blends two inputs using an optional opacity. It performs a blend operation
|
||
|
|
defined by the blend mode between both inputs, and mixes the result with the bottom input
|
||
|
|
using the opacity (defines by the *opacity* parameter, or the optional greyscale input).

|
|
||
|
|
* The second input is the bottom layer.
|
