Blend node
|
||
|
|
~~~~~~~~~~
|
||
|
|
|
||
|
|
The **Blend** node blends 3D texture 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).

Inputs

|
......
|
||
|
|
|
||
|
|
The **Blend** node accepts three inputs:
|
||
|
|
|
||
|
|
* The first input is the top layer.
|
||
|
|
|
||
|
|
* The second input is the bottom layer.
|
||
|
|
|
||
|
|
* The third input is an optional mask that will be use instead of the opacity parameter.
|
||
|
|
|
||
|
|
Outputs

|
||
|
|
|

|
|
The **Blend** node outputs the result of the blend operation.

Parameters
|
||
|
|
..........
|
||
|
|
|
||
|
|
The **Blend** node has two parameters:
|
||
|
|
|
||
|
|
* The *blend mode*, that can be one of the following: *Normal*, *Multiply*, *Screen*,
|
||
|
|
*Overlay*, *Hard Light*, *Soft Light*, *Burn*, *Dodge*, *Lighten*, *Darken*, *Difference*.
|
||
|
|
|
||
|
|
* The *opacity* used when mixing the result of the blend operation with the bottom input
|
||
|
|
when the corresponding input is not connected. When connected, the opacity channel is
|
||
|
|
converted to greyscale and multiplied with that parameter.
