Veritas,

You have indeed been a frequent and helpful contributor to this forum. I am most appreciative of that fact. But I do have a problem with Vue spending their precious resouces on support for Piranesi, as it is VERY EXPENSIVE ($750 for only a renderer?) and mostly a niche market.

Besides, at least one of the pictures you display above is mostly just a hand-colored render of an effect you can get with the free SketchUp 3D version from Google. While I know Piranesi helps paint existing images with z-buffers, there is still significant skill required to know how/what/where to place your brush strokes, what color etc.. It doesn't only come automatically with Piransesi as you might think.

Thanks again for your  helpful posts.  -Chipp
