Directional Light Attributes

All light types share the Directional Light attributes and options.

For a description of Maya’s Directional Light, see Create > Lights > Directional Light.

Type

Click the arrow to choose a light type from the drop-down list. When you change a light’s type, only those attributes common to both types retain their previous values or settings. Values and settings for non-common attributes are lost. When you change a light’s light type, the light’s position is also preserved.

For more information on Maya’s light types, see Sources of direct light.

Color

Determines the light’s color. Click the swatch either to change the light’s color in the Color Chooser or to map a texture to the light. If you map a texture, the light projects it (depending on the light Type). The default setting is white. The following shows the rendered result when you map a Ramp texture to an Ambient light’s Color attribute.

Intensity

Represents the brightness of the light. A light with an Intensity value of 0 produces no light. A light with a negative Intensity value removes light from a scene in the area of the light’s influence. The slider range is 0 to 10, but you can type in a larger value for a brighter light (for example, 20). The default value is 1.

Tip

Use a negative Intensity value to reduce or remove hot-spots or glare.

Illuminates by Default

If on, the light illuminates all objects and is included in the defaultLightSet. If off, the light only illuminates objects to which it is linked. Illuminates by Default is on by default.

Emit Diffuse and Emit Specular

Emit Diffuse and Emit Specular are on by default. Turning them off turns off the diffuse or specular shading results for the light.

Note

The results do not show in the scene view. To see the results, test render in Render View.

To enable or disable the diffuse and specular shading for multiple lights at the same time, use the Rendering Flags window (Window > Rendering Editors > Rendering Flags).
