== Get Local Var Node ==
== Grayscale Node ==


The Get Local Var node ''( shortcut: G key )'' allows access to local values created via a [[Unity Products:Amplify Shader Editor/Register Local Var|Register Local Var]] node. This can be done by selecting a local variable through its [[#paramReference|Reference]] property available at the Node Properties window or upper left corner of the node body.
The Grayscale node outputs a grayscale float value from the color value specified on its [[#paramRGB|RGB]] property. Several styles can be selected via the [[#paramGrayscaleStyle|Grayscale Style]] property to achieve different results.
<br/>'''NOTE:''' Using this node is similar to directly connect the '''Register Local Var''' output to where the value is needed.

Grayscale Node

The Grayscale node outputs a grayscale float value from the color value specified on its RGB property. Several styles can be selected via the Grayscale Style property to achieve different results.


Nodes used: Texture Sample, Grayscale

Node Parameter Description Default Value
RGB Color value to be converted to grayscale. Only visible if the respective input port is not connected. 0,0,0
Grayscale Style Available styles to calculate a grayscale value from a color.
  • Luminance: Uses Unity internal Luminance function ( Dot product between color value and unity_ColorSpaceLuminance)
  • Natural Classic: Dot product between color value and vector 0.299,0.587,0.114
  • Old School: Calculates color average value ( sums all channels and divide by 3 )
 Luminance


Input Port Description Type
RGB Color value to be converted to grayscale. Vector 3
