I just received Vue 4 for Christmas. So far, I haven't had time to do anything with it but render a few existing PZ3 files, but I'm already impressed. But what is impressing me the most is the User Guide. It is excellent! Like where it will tell you about an option (like superior-anti-aliasing), then tell you that you probably won't want to use the option because it won't make that much difference. I'm used to user guides that say things like, "The bmxue options selects how many bmxues you want in your picture," without telling you what a bmxue is. I am very happy! lynn
