I created a first UE4 plugin UE4-Kdtree.
This plugin provides the user to build kd-tree and radius search from it.
I developed this plugin because there was no Blueprint interface about kd-tree when I used UE4 at first time.
I’m a newbie about UE4 plugin development, so the comments and requests are very welcomed on GitHub Issue page or this topic.
