Oh man... I just looked at this bad boy and it's not as hard as i was imagining it. I'm currently working on a medium scale, destroyed building set. it's going ok. But I was originally gonna fotoshop the background in (of destroyed buildings) but I'm gonna go a slightly different route. THanks for this. It really helps!

Your welcome, it really is very simple, just takes a little time.

I don't know how I missed this one. The genius is in the simplicity; so easy to do, yet so effective. I have to give this a try. Thanks Dave!
