I used to work with tree druid, the plug-in version. (which now doesn't work with newer releases of Carrara) The stand along should be just fine. Neither option does roots - what look like roots are actually the branch shapes projecting on the ground grid. However, Carrara 5.1 DOES let you bend trunks, brances, change leaf shape, add custom leaves, add gravity etc. Basically everything that TD did. The one thing that Carrara does not let you do that the TD plug-in did is grow a tree over time/animation - that was great. I don't beleive the stand-alone version will do that either. Mark
