Well, considering there are few left in the community who even know how to do things like you're requesting, the demand is high for us to do it. I'm doing what I can to help others learn how to do objects, but my time is limited and I'm very busy.
You could always just do what I did... teach yourself.

There wasn't anyone around to tell us how to do it. We basically just learned how to do it by opening up similar objects (to those we were making) in the Object Editor and seeing how the game designers build things.
But tell us your ideas for water features. Maybe I can use your ideas when making the tutorials. I'd rather build things people want (while doing the tutorials) than just making things for the sake of the tutorial.
