Unreal project entirely in C++?

Is it possible to write a Unreal project entirely in C++, like OpenGL or DirectX? I am looking at writing a vr application, and would like to use Unreal’s support for vr. However I also need to collect data from external sources using a data acquisition driver.

Thanks

Unreal is C++. Unreal isn’t it’s own language or anything. It’s all C++ in the end. So yes, you can use it to just write a VR application or what not.
