Gentlemen, this has to be one of the most innovative tools I've had the pleasure of using.
FXEditor by that tireless developer; Arno Gerretsen. The editor is simplicity and plain logic itself. And it's freeware too.
Just point the editor once to your particular fs installation and, hey presto! load up any of your installed fx and SEE the effect in action in the editor's view screen. You can adjust any of the values and AUTOMATICALLY SEE the optical changes as they're made, including animation!
Couldn't be simpler. Go for it here! http://www.scenerydesign.org/development-releases/
