Unlike tree add-ons like Sapling, Space Tree Pro by Michael Anders allows you to shape your trees. Simply create blocking objects in their environment or draw shapes with a grease pencil. It looks amazing.
I am happy to announce that my new tree add-on, Space Tree Pro, is available on Blender Market.
It's a logical evolution from my free space tree add-on and it features, among other things, a hugely improved user interface focused on an easy work flow, persistent settings that are saved with your tree for later tweaking, interaction with the grease pencil, a comprehensive manual, ready to use sample trees and a set of video tutorials. I hope you'll like it and feedback is welcome as always. I will of course continue to write free stuff as well, I haven't gone over to the dark side completely :-)
