First we create a Mountain in which we´ll embed later the Waterfall.

So we make a Mouseclick on "Terrain"

The new created Terrain is to low for our Waterfall so we should raise it..

Now we need to create the Place for our later flowing Waterfall...

Doubleclick on our Mountain and you´ll start the Terrain-Editor. With a little soft brush and "lower" Setting, we´ll cut an etch out of the Mountain like shown beside.

Ready is the Swiss - Cheese ;-)

...with a little Imagination you can see the Position of our later Waterfall yet allready...

.to make it easier we´ll cut the bottom away. Use the Cut Tool on the lower Site of the Editor (marked in red) draw it to the right until the bottom dissapaers

Now click on OK, our Mountain is prepared!

No we turn the Terrain in the way that the camera points directly into the gap!

Allright, that looks not to bad.....

Now we create a symetrical Terrain instead of clicking right on the Terrain Icon and then leftclick on "symetrical Terrain".

The Advantage is that all changes took place on the top and bottom side of the Terrain

But we need something other than a Mountain, so we "reset" the Editor with the button marked in red!

Now we paint a bow like shown beside.

To imagine what we do here look onto an Waterfall from the side (just in your mind ;-) )

Once again we´ll use the cutting tools to cut away the botton.

Click on Ok to use the created Object.

The created bow has now to be inserted "into" the fitting gap we earlier create...

The best way to do this is to do it by "try and error method" ;-)

That´s the technical part... yes really, that´s all, now let your mind create your picture.

Certainly you´ll need flowers / dust / water etc.

A litte tip:

The Vue own Material in Fluids: "Milk" could be excellent used with a rough filter for the Waterfallstream!

Take a look on my first Picture trying this method!
