To add it in post, you would render the shadow onto a white surface with nothing else, jus the shadow.
Then you would take this into an image editing package, load your scene pic, then in another layer load the shadow and set the shadow layers Mode to 'Screen'.
This would get rid of the white and overlay the shadow onto the scene.
If it covered anything it shouldn't that would be easy to work around with some selection.
The smoke in my scene was rendered in LW, but I rendered it in a scene on its own, and layered it over the other image of the whole scene.
There is nothing in the rules that says you are not allowed to use post production techniques, so you could get you electricity to really BUZZ!
