Complete newbie here. I'd like to create my own plant symbols using imported PNG trees for the 3D view, and custom tree symbols for the 2D shape. I haven't found a good tutorial on how to do this. I've managed to get as far as creating a symbol from the imported PNG image, but very confused about how to go about actually creating a new plant (other than select Landmark>Create New Plant).
**More specifically I am getting an error message that my symbol (the newly imported tree image) does not have 3D geometry when I try to select it for the 3D GL view.
