ZN_FastNoiseLite¶

Inherits: Resource

Generates coherent and fractal noise using the FastNoiseLite library.

Description:¶

This is an alternative implementation of FastNoiseLite, based on the same library. Some differences include different default values, and use of period instead of frequency in fractal parameters. It is also used in the voxel module in order to bypass the overhead of Godot calls in GDExtension builds.
