Jobu, sorry about that, but about all that I can suggest is that link up there is a great place to start... Waterfalls are a real difficult... another place you may want to look at is at the link above... although this is made for bryce, you can get an idea on how to do it in vue d'esprit... and yeah, forums are like that, people start talking about one thing in one post and then subjects sometimes change... :)
