After struggling for the last couple of months , I was finally able to put together something which works
I have created, what I like to call, a "live scene editor".
Here you basically move around in a scene, as an avatar and make changes to it.
You can check it out here

Be warned that it might be very buggy.
Still working on instructions on how to use it.
