Overview
This node generates Perlin noise and outputs the noise value as a scalar. The output value ranges between -0.5 and 0.5.
Here is an example of the noise pattern generated by the node. Please note that this image has been adjusted somewhat to make the pattern a bit clearer.
This node requires a Get position, Get position in geometry, or Get position in texture function node to be assigned to its Main input so that the current Render State knows where a sampled point is located in texture space.

Settings:
- Scale: This setting controls the overall scale of the noise pattern generated. Increasing the value results in a larger pattern overall.
- Seed: The setting controls the noise pattern generated. Each seed value generates a slightly different pattern.
