Thanks Guitta and riversedge for validating my rantings. The tutorial, as it is worded in the manual, is unworkable. And Guitta, your reworded Steps 8 and 10 worked perfectly except I had to create 2 new key points when editing the filter to get what you have pictured above. And don't forget, none of this is possible unless you're working on a simple--not mixed--material. (The grass material that comes with Vue 4 is mixed.) Oh, and thanks for the link Guitta, I'll check it out now.
