I don't have ver.6 yet, and I probably won't upgrade until they fix the material and terrain animation bug in an update, or when ver.7 comes out. It's already been announced that Bryce7 will have replicators, much like Carrara5 does now, and that would be a feature that would make me just have to upgrade. I am still able to do some good work in ver 5.1, though like you, I don't post a new one very often.
