If you move the camera, objects are sorted according to the axis the camera is pointed towards.
When Z-buffer is off, the distance of objects from the camera eye is not considered. Objects are drawn in
the order shown in the Priority Editor. To follow the previous example, you can turn off Z-buffer and change
the priority of Image B so that it is drawn on top of both Image A and Image C. The Z position of these
images is therefore ignored.
Shadow Mix, like Z-buffer, arranges objects according to their distance from the camera eye. Use Shadow
Mix so that each shadow is rendered in the correct Z order with its corresponding surface.
