The plant modeler hasn't changed. But being able to add thousands of trees and shrubs to landscapes without creating a monster file is. I've found controlling them is very similar if not easier than Vue5 Infinite. Landscapes can now tile. Carrara doesn't ship with as many "sophisticated" plants as Vue. However, you can actually create them and control them to a level equal or better in Carrara - if you're willing to learn the plant editor that is. Physics is unchanged at this point. There are new joint/ik capabilities making it easier to finesse posing.
