Thanks. I appreciate the links.  I did this when I was teaching myself SU and was trying to find out if rendering was something I wanted/needed to use. I will have a look at the links you have posted.
I guess the reason why I don't really render things is because what is important for my work is the walk-though aspect of SU which, I think, you cant really do it on. It is kind of fun creting cool looking things just for the sake of it though.
This one is with SU and photoshop.  This is a really nice old building I was doing a landscape design for when I was studying and I got kind of distracted and put this together.
