Fractal noise usage

[antoine-perez]

How is the fractal noise node meant to be used? What should I plug into the coord (vec4) socket? I'd like to generate a world-space 4D noise to displace vertices.

Hello Antoine.
The coord input should be the coordinates used for the noise.
Typically the first 3 values will be the surface position, and the fourth value can be used either as a seed or as a time parameter.

Here's an example:
