Hi,
Sorry, as the Advanced CMake projects are incompatible with the regular VC++ projects, the VS IntelliSense won’t work for them, hence the Clang IntelliSense is the only option.
Please feel free to let us know if the Clang IntelliSense doesn’t handle some specific cases – we might be able to resolve this. We are also working on an experimental engine build based on the latest Clang 6.0 that improves compatibility with the latest C++ features.
