Setting Up the Multiplane
To construct a multiplane, you must imagine what a real environment is like. Take a look at your background picture and imagine a camera moving across the space. You will notice that objects in the picture would move at different speeds depending on where they are in relation to the camera lens.
Building a multiplane requires an understanding of the scene's background as well as the positioning of the elements on different layers.
For example, in this background, the main objects to be separated are:
Although the bottom of the tower is hidden behind the plant and the ladder, each of your multiplane layers should be a complete drawing. This is because hidden portions may show up during a camera movement later on in the scene
