Hi, I'm MightSwordbio, AKA Satthukaraoke to someone. I'm a builder that aim for creative, not beauty, like anyone has seen my collection on Wonder of the Ancient World will know. Today I'll walk you through one of the thing I think very creative, a waterfall.

First, Raise the terrain as high as you want. Then smooth the face that you will want to make your waterfall (south in this case)

Use the fence tool and draw a fence on the edge of the cliff (use any fence you want, except the last fence).

Choose the water too with the biggest circle. Now here is the tricky part. You have to place the cursor exactly like I do, with the center dot right at the fence, or else the water fall won't appear. Hit the mouse to do the water, then keep the mouse pressing until thing go red like the picture.

Remove the fence, and there is your waterfall :D

A little help with the moveobjects cheat and thing doesn't look too bad. But this is optional, the waterfal is built without any cheat, just trick :D
