where is StaticMeshActor "Generate Overlap Events" in source?

[NukeCorruption]

I don’t think my UE4 engine is getting compiled now that I think about it.
I’m using UE4.27
I read this and followed it but it doesn’t actually compile the engine even if I put to “Development Editor” conf and re-build from scratch. It just said it succeeded after like 1 second

I made changes to the unreal engine software, but I can’t find any option to recompile the engine so that the changes I made have effect, only recompile the project but this I already did and the changes made had no effect, I am weeks trying to find a way to recompile all the code of the content of the unreal engine that I made the changes but I do not find this function available in Visual Studio 2019.

I got “UE4” in the Solution along with my project, I even tried making all the engine source “non-readonly”.

Any ideas why engine doesn’t rebuild?
