Is it ripoff from one of Unreal Engine stream?

No, but I guess you mean one of the streams where they showed their internal vine generator used for Paragon that also aligned to surfaces. Well, if making a surface-aware asset generator that also includes vine generation would be considered as a ‘ripoff’ then something would be wrong 
You see, surface-aligning generation is nothing new and I even remember a 3dsMax plugin that generated ivy from couple of years ago. … And to completely soothe your curiosity, I’ve started working on this tool long before the stream appeared, back in 2015 - originally it was meant to be a part of my previous Dynamic Tree & Plant Generator, as an automatic ivy growing around generated trees - but it evolved into this separate product.
