I've been working with the "noise" node many times in Unreal because its very useful for quick iteration or high quality output without flipbooks and whatnot, however there was always a big limit for me, which is the not exposed parameters, so I decided to make some material functions encapsuling hlsl custom nodes, which allows you to control the parameters via material instances, and dynamic parameters. I included all the computational noises,plus the texture based simplex one. They are broken down into a per function base, because an all in one would result in 4k instructions... This way you can have them fairly cheap, and customizable with levels and other stuff exposed. I did not include "turbulence" parameter because that can be done be taking the absolute value of the result and originally it was in the main loop so I saved me some instructions.

Voronoi is separated into qualities because of optimization reasons...
You can do "turbulence" like this:

Have fun, thanks for your support :)
