29 Adding Lighting Effects Adjust the Light controls, as required. To delete a light: 1. In the Workspace panel, select the light. 2. Choose Edit | Delete, or press DELETE. The light is removed from the composite. Note: If you delete all the lights in a composite, you can still access the ambient light settings in the Timeline. Renaming Lights If you create multiple lights, Combustion appends an increasing number (in parentheses) to the name of each. For example, if you create three lights, they are named Light(2), Light(3), and Light(4), by default. The default light is named "Light".You can rename the lights, including the default light at any time. To rename a light: 1. Select a light from the Current list. 2. Type a new name in the Name field. 3. Press ENTER. The name of the light is changed. Note: You can also rename a light in the Workspace panel or Timeline. Moving and Rotating Lights You can move a light anywhere in the composite just like you can move a layer or the camera. You can also rotate spot lights to point the beam at different objects. You can position lights either by setting X, Y, and Z coordinate values or by dragging the light in the viewports. To move a light: 1. Select the light. See Selecting Lights. 2. Do one of the following: • Click the Transform button and adjust the required fields to set explicit values for the position of the light. • Click the Arrow tool in the Toolbar to drag the light to the required position in a viewport. Enable the X, Y, and Z tool options to constrain the movement to one or more axes. Note: Depending on the view, you can constrain movement when you left-click and drag, and when you right-click and drag in the viewport. See "Tool Constraint Shortcuts" in Chapter 5, "Compositing''. The light icon moves to the new position. Note: Moving a spot light does not change the rotation of the spot light cone. To point it at different objects, you must rotate the spot light. To rotate a spot light: 1. Select the light. See Selecting Lights. 2. Do one of the following: • Click the Transform button and adjust the required fields to set explicit values for the light's rotation. • Click the Rotate tool in the Toolbar and drag the light to the required rotation in a viewport. Enable the X, Y, and Z tool options to constrain the rotation to one or more axes. Targeting a Light You can target a light to a layer to make the light point at that layer no matter where it is in 3D space. Once you set a target, the light rotates to point at the target if it, or the target, moves. This is particularly useful with spot lights and when creating animations. You can also create a null object, which you can use as the light target. A null object is an invisible object; 736
