You can use the Place Highlight on page 1018 button to change a light's
position. See the Procedures section, below.
A
Light viewport on page 7614can be a useful way to adjust spotlights in
your scene.
Procedures
To create a light:
1
On the Create panel, click Lights.
2 Choose Standard or Photometric from the drop-down list. Standard is
the default.
3 In the Object Type rollout, click the type of light you want to create.
4 Click a viewport to create the light. This step varies slightly depending
on the type of light. For example, if the light has a target, you drag and
click to set the targets location.
Light objects replace the default lighting. As soon as you create a light,
the default lighting is turned off. If you delete all lights in the scene, the
default lighting is restored.
5 Set the creation parameters.
Like all objects, lights have a name, a color, and a General Parameters
rollout.
To create shadows, do one of the following:
1 In the General Parameters rollout, make sure On is checked in the
Shadows group. Adjust shadow parameters in the Shadow Parameters
rollout and the additional (
Shadow Map on page 5135, Advanced Ray-traced
on page 5118, Area Shadows, on page 5122 or Ray Traced Shadows on page
5133) shadow rollouts.
2 Right-click the light, and turn on Cast Shadows in the Tools 1 (upper-left)
quadrant of the quad menu.
Turning on Cast Shadows also turns on the On toggle in the Shadows
group of the General Parameters rollout, and vice versa.
Shadows are visible only when rendered, either in a full rendering on
page 6065,
in a viewport on page 4991, or with ActiveShade on page 6102.
