Libnoise is GPL licensed so you flat out cannot use it in an Unreal Engine project.
Shame as UnrealLibNoise is a nice way of configuring modules in blueprint…but no use for anything you plan to release. I do plan on adding module/layers support to the Fastnoise wrapper. Going to give a quick talk on the terrain generator at our user group next week so I’ll be spending some time on it, adding the foliage placement, upgrade to 4.12, trying out koderz’ runtime mesh component etc.
