Turns out the free PLE version of Vue 6 Infinite is able to export terrains. The Vue terrain editor is a lot like I think Bryce's terrain editor should be. Still PRETTY quick and simple, but more capable. I think being able to work on the zoomed area is beneficial(in a big way), and the erosion algorithms are immensely superior, especially alluvium. I still prefer Slope Noise and Height Noise in Bryce. Here are the results. I added a bit of height and slope noise and a last stage of simple precipiton in Bryce, 'cause the higher areas tend to get a little smooth with Vue erosion.
