== Noise Generator Node ==
== Projection Matrix Node ==


The Noise Generator node creates a '''Float''' noise value on a '''[-1 1]''' range using the method specified by [[#paramType|Type]] according to a value specified at [[#paramUV|UV]].
The projection Matrix node outputs the current Projection Matrix which can be used to transform either a position or direction vector from view space to clip space.
<br/>'''NOTE:''' Input data must vary across the the geometry since equal values will generate the same noise. A simply way to achieve this is to connect a [[Unity_Products:Amplify_Shader_Editor/Texture_Coordinates|Texture Coordinates]] node into its input.

Projection Matrix Node

The projection Matrix node outputs the current Projection Matrix which can be used to transform either a position or direction vector from view space to clip space.

NOTE: We advise using either the Transform Position or Transform Direction as they are easier to use and you wont need to do an explicit multiplication between matrix and position/direction value.

Output Port Description Type
Out Returns current projection matrix value. Matrix4x4
