Er, any updates on this? Is this still the only way to delete a class…?
I tried to follow this and now my project is essentially broken:
- Deleted cpp and headerfiles (the only ones I created)
- Deleted folders ‘Intermediate’, ‘Saved’ and ‘Binaries’
- Recreated project files
- Cleaned my game project
- Tried to rebuild only my game (for some reason it compiles the whole engine instead)
- Got many horrific compiler errors (cannot post it here due to message length restriction)
- Tried to open the project from the launcher, had to recompile once more (lasts for about an hour now)
- Got this message
[21/1322] Link UE4Editor-Core.dll
LINK : fatal error LNK1104: cannot open file ‘D:\Documents\Unreal Projects\VRShowRoom\UE4_Oculus\Engine\Binaries\Win64\UE4Editor-Core.dll’
What have I done… 
Is there any possiblity to get rid of ALL CUSTOM C++ CODE? I just played around with CPP a few hours to create a custom component (didn’t work) but it sees like I opened the box of pandora…
