I have inserted some trees as one forest object in "Custom Edit" Mode. I try to move a single tree of this object. When I´m in the "Modify" panel and click the Subtree "Trees" I can not select a single tree as shown in the help and video files. I called a guy from Laubwerk and he was able to select a single tree. What I can do is to add a new tree to this object, but when I want to detach one, I can´t do it, because I can´t select a single tree. What do I wrong. Please help.
