C++ static map plug in

Hello Everybody,

I have a static map written in Visual Studio, C++ and DirectX

It is a DirectX program that reads pre-captured DirectX data from DB (binary file) and renders the objects using DirectX 9. It is basically a static map of a game.

What I want to do is embed this map rendering code as a plugin into Unreal Engine 4. (let’s call it “map plugin”)
so that I can use Unreal Engine 4 to add other original objects on top of the map.

I was wondering if someone had done anything like this previously and has any hints or tips on how best to accomplish this. Or any tutorials, examples or the best place to start.
