Yup, right on, John. For static rendering, Pro doesn't add all that much. Plant Editor, better OpenGL, a couple of new rendering options, network rendering and mesh simplification. Of course, if you want to be able to export, then you'll need Pro. I personnaly cannot complain about Vue Pro's stability. I find it pretty stable. It's crashed a couple of times (like any other piece of software), but nothing worth spilling my guts about. I'd say both are an excellent choice, depending on what you want to do and how your budget stands. Pete
