The addon is still in a heavily early build and will have more to it soon. I am still somewhat new to Java so the code may not be the best, but within test runs I can generate 1 million perlin values in 0.6 seconds (With nothing but setting a local variable to the value.)

This addon allows you to create noise generators, and edit them with a lot of different values!

You can view more information about the expressions on the GitHub release. https://github.com/ReportCardsMC/SKNoise/releases/tag/1.0

(We also have SkriptHub documentation, working on SKUnity documentation as well)
