I have to agree with pisacces that using the terrain editor in Vue to get more than a happy accident is difficult at best. I can never seem to get the terrain I want, but usually have to work around the terrain I can get. Yeah, you can use the airbrush and various modes, but the painting is rather inexact. Lately, I've resorted to using a modeler to get the exact shape I want rather than the terrain editor. The TE works great for mountains and such, but if you are looking for exact landscaping (like around a house), I've found the modeler to be a godsend...
