I've used SketchUp for a few years now in architecture school and I have always hated it and used physical models and hand drawings to do my work. When I stumbled upon this site I was immediately surprised by the work that has been done in this program. So, I come to you all, the only experts on this program that I have ever seen, and ask you for your preference on renderers. Whether they be plug-in or free standing, which are the best, in your opinion, and why?
Feel free to post images of examples you have too, that would be a great help.
I know that a lot of you only build the form for perspectives that you then do in photoshop, but since I already know how to do that I would like to focus on an automated program.
