| - | Plants are built out of components which are defined by two texture images. The first texture is the one which is rendered on screen. The second is used to define where the connection points are, indicated by black blobs - this is where child components will be connected to. These blobs can be put anywhere in the texture and are automatically located and used by the program. You will be able to put all these textures into a directory and the program will build plants for you for previewing. | + | Plants are built out of components which are defined by two texture images.

| Each component is only allowed one place where it connects to it's parent, which is always at the bottom of the texture, in the middle. Leaves don't need connection point textures as they don't connect to any child components, but still need their parent connection point at the bottom. | Each component is only allowed one place where it connects to it's parent, which is always at the bottom of the texture, in the middle.

You can edit the connection point textures, and rerun the program to adjust the positions of the components. | + | A resulting lollypop tree.
