I would like to have a lab for small plants not only trees and bushes...some flowers and such more like the nice application plantstudio. More control in treelab a little more like onyx tree. If one say: Costs...well some of the features can be used for plugins to sell for other software too. E.g. a cooperation with cinema4d so they create some plugins for bryce and the bryce trees or such would be available too for cinema. So the users of both applications would like the results. (I used cinema because of the good renderer there) And my favorite: Weatherlab That would work best with particles for sure. All kinds of weathereffects with enough flexibility not only to mimic the real weather on earth but to create new weather for more fantasy of science fiction creations too. Another favorite: Melting objects that flow e.g. like lava. Thomas
