Here's my two cents: Making your own boulders and rocks in Vue is easy. See my pic in the gallery called "Lake Vue". The rocks in the foreground were all made in the terrain editor. All you do is make a terrain, go into the editor (double click the terrain or right click and choose "Edit"), and I like to filter the altitude to about half way before I start making the individual rocks. Then I make some mounds until I think it looks "bumpy" enough, and paint the ground away in between the bumps. After I achieve the look I want, I smooooooth them out and voila! Stones suitable for creeks, rivers, lakes or anywhere you'd care to put them. Hope it helps :) Ta ta, Laurie
