I have some interest on UE4. Currently, I am developing a mobile game, and have a pretty large existing codebase written in C++11/14 with Clang.
AFAIK, UE4 is using a custom compiler (preprocessor? whatever), and that means C++ compatibility may differ on their own tools. How is the support for C++11/14 on UE4?
UE4 supports C++11 as stated in their Coding standard
and "Unreal Engine is built to be massively portable to many C++ compilers
"
which means, it builds with the default compiler of Visual Studio or Xcode
