When accessing Action as a Timeline FX, you have access to a quick menu with some of these Light settings. To see the full Light menu, click the Editor button to enter Action.
Basics Tab
- Light Type box
- Select the type of light to apply to the scene.
Light Type: Description: Example: Point / Spot A point light radiates light uniformly in all directions. A spotlight radiates a cone of light centred along the spotlight direction. Use the Spread field to change the spread angle. A spread of 90° or less creates a spotlight. 
Directional A directional light shines evenly in one direction only. The light icon in the scene displays an arrow showing the direction of the light. Use a directional light to simulate a very distant point light source (for example, the sun as viewed from the surface of the Earth). 
Ambient An ambient light shines in two ways—some of the light shines evenly in all directions from the location of the light (similar to a point light), and some of the light shines evenly in all directions from all directions (as if emitted from the inner surface of an infinitely large sphere). Use the Shade field to set the percentage on ambient light applied. Note: The ambient light type is not the same as the global Scene Ambient lighting available for the whole Action scene.
Rectangle Area A rectangle area light is similar to a point or spot light except that it produces a hotspot based on the shape of the rectangle. Use the area size fields to set the size of the rectangle. 
Ellipse Area An ellipse area light is similar to a point or spot light light except that it produces a hotspot based on the shape of the ellipse. Use the area size fields to set the size of the ellipse 
Different settings may appear directly below the Light Type box depending on the type selected.

- Scene Ambient button
- Enable to have global ambient lighting in your Action scene. This same setting can be found in the Action Setup menu and the Light menu.
Profile Tab
Settings for controlling the light bevel curve are located in the Light Profile tab.
- Light Intensity field
- Displays the intensity of the selected light. Available in the Light menu Basics and Profile tabs. Editable.
- Light Spread field
- Displays the spread angle. A value of 90° or less creates a spotlight. Available in the Light menu Basics and Profile tabs. Editable
- Light Attenuation field
- Displays the level of amplitude of the light. Available when Parametric is selected in the Falloff Model box. Editable.
- Light Falloff field
- Displays the amount of falloff around the edge of the light source (also changes the size of the specular highlight). Available when Custom is selected in the Falloff Model box. Editable.
- Decay Type box
- Select the type of decay to apply to the light source.
- Decay field
- Displays the rate at which light decreases for the chosen decay type. Editable.
Falloff Model Settings
- Falloff Model box
- Select whether to use a parametric or custom falloff model. A custom falloff allows you to interactively use the profile curve, while a parametric falloff displays the curve for visual reference only.
- Falloff In field
- Displays the level of incoming light falloff. Available when Parametric is selected in the Falloff Model box. Editable.
- Falloff Out field
- Displays the level of outgoing light falloff. Available when Parametric is selected in the Falloff Model box. Editable.
- Light Bevel curve
- Displays the specific profile of the selected light. Use the options in the Tools box to add, select, delete, or move keyframes on the bevel curve. When using a parametric falloff model, the curve is read-only. See Using the Light Bevel Curve.
- Home button
- Resets the Bevel curve viewer to show the whole curve.
- Undo button
- Undoes the last set of Bevel curve operations.
- Reset button
- Resets the Bevel curve.

- Lightbox Normals button
- Enable to take normals into consideration to compute the transparency of the Lightbox effect on the scene.
- Effect field
- Displays how much the orientation of the normals affects the result of the shader, relative to the light position in the scene. Available when Lightbox Normals is enabled. Editable.
- Override Normals button
- Enable to force all surfaces to be affected by the Lightbox shader, when Light Normal attenuation isn't appropriate for the Lightbox effect. Disable to only affect front-facing surfaces, relative to the light. The default behaviour of this button can be set as an XML tag in the shader.
GMask Tab
Use this setting when a GMask is connected to a Light with a GMask link.
- GMask Link Texture Size box
- Select the texture size of a GMask connected to a Light through a GMask Link.
