Hi, have you sovled your problem? And can i ask you a question , hava you finished the first step that successfully built the UELibrary and generated UE4Editor-UELibrary.dll according to the page here ,Building Unreal Engine as a Library | Unreal Engine 4.27 Documentation? I tried to add the code in the page mentioned above to my project’s *.Target.cs file, to be specific i add the code to UE4Editor.Target.cs file because i choose the Development Editor configuration on Win64. but when i build there are lots of error. i also tried to create my project by UE4 engine and add the code to my myProject.arget.cs, None of these approaches can implement the new feature.
