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 spotlights 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; it has no pixel information or dimensions, and is not rendered in the final output.

To target a light:

1. Select the light. For more information, see Selecting Lights.
2. Select the layer that you want to set as the target from the Target list, or click the Pick button and select it in a viewport.



The light is targeted to the selected layer. When you move the target, the light rotates to point at it.

To target to a null object:

1. Select the composite.
2. Choose Object | New Null Object.

Note: This option is also available in the context menu.

A null object is added at coordinates 0, 0, 0.



Note: If you create multiple null objects, combustion appends an increasing number (in parentheses) to the name of each. For example, if you create three null objects, they are named Null Object (1), Null Object (2), and Null Object (3), by default. You can rename them at any time.

3. Select the light.
4. Select the null object from the Target list.

You can now move the null object. If necessary, the light changes rotation to point at it.
