Vue...enjoyed my time in Bryce but Vue does much more,,,better now than it was but Vue can do things like populate across a feature with variance. For example...you have a plot of land that you want rocks and trees on. Choose the trees and choose the rocks and Vue will populate it for you. You can set controls for everything about your lil environment. From how much the trees say differ from each other to the altitude and slope range they form on. Is fairly easy to jump into but very very deep.
