# Noise 2D

A 2D Perlin noise generator.

## Parameter Types

Parameter Types Parameter descriptions Discussion The Noise 2D shader node procedurally generates Perlin noise patterns that you can use to add texture and variation to materials. All noise values that are procedurally generated are numbers between 0 and 1 before the amplitude and pivot are applied. Below is an example of a simple node graph that uses the Noise 2D Node to generate a black and white pattern procedurally: Image(source: “Noise2dGraph”) Multiply the incoming texture coordinates with a constant float. The float changes the frequency of the generated noise to a higher number that corresponds with the pattern repeating more often. Below, the resulting texture applies to a cube:
