Some 3D effect parameters that affect the size, position, or movement of an image can be adjusted in two ways. You can adjust the parameter using the controls in the Effect Editor, or you can click the button for the parameter on the right of the Effect Editor and use the on-screen handles to make direct adjustments. The individual parameter descriptions in this chapter show the parameter button as well as the parameter controls for those parameters that provide this option. For more information, see Manipulating 3D Effects Directly.
