Well, my point of view on this matter is... "Terragen like landscape" is nothing but ONLY land, sea & sky, that is why they look different! That is why it's I think this is a handicap software, it creates ONLY beautiful no-mans-lands. You can achieve that in Vue at no time and very easily. The problem presists somewhere else ... after you create "terragen like landscape" in vue, you have so many options of vegitations and objects, you start adding them in your scene. And before you know your "terragen like landscape" becomes "vue like scenery"! Look at "kenwas"s gallery (the link above), I'm sure terragen artists would die to do these kind of landscapes.
