 #### Option 2: Modify Few Files
 Unreal versions newer than Unreal 4.15 has breaking changes. So you need to modify your *.Build.cs and *.Target.cs which you can find in the `Source` folder of your Unreal project. So what are those changes? Below is the gist of it but you should really refer to [Unreal's official 4.16 transition post](https://forums.unrealengine.com/showthread.php?145757-C-4-16-Transition-Guide).
