Any demo showing AR in Cryengine?

I am searching for a demo showing how AR could be done in Unreal or an example.
Can anyone help me?

The thread name is a bit confusing…

If you youtube unity3d AR, you see aloooooooooooot of youtube videos showing AR done in Unity3D.
I want to see some AR demos done in Unreal, to see if I switch to unreal or not, got me?
