A small Road-Tool I made, to make laying out roads in UE4 easier. The video is a small demonstration.

I made this program to easier install UE4 on Linux via a launcher tool. Later I added some tools (Back-Up and restore projects, add content of one project to another). The launcher is able to start UE4 in OpenGL3/4 as well as with primusrun. Further more, you can control where it searches for projects and some other useful stuff.
Have a look at the Videos!
