Cast Shadows Turns on shadows for the light, for viewport display. This
setting does not change the value of the light’s Shadows toggle, so it doesn’t
affect the rendered scene.
Viewport Lighting Turns on the selected light, for viewport display. This
setting does not change the value of the light’s On toggle, so it doesn’t affect
the rendered scene.
Light On Turns the selected lights On. This setting does change the value of
the light’s On toggle, so it does affect the rendered scene.
Select Light Target If the selected light is a target light, choose this to select
the target object. This option doesn’t appear if the light is not a target light.
Animating Lights
You animate lights by using transforms or changing creation parameters on
different keyframes while the
Auto Key button on page 7549 is on. During
animation, light transforms and parameter values are interpolated between
keyframes.
Moving and Rotating Light Objects
You can use the following methods to move and rotate light objects.
■ Move an
omni light on page 5063 when it’s a "practical" light within a scene
(a light that appears in the scene itself). Combine the light with a
self-illuminating geometric object. If you want to move a target type of
light, select both the light and its target to animate them together.
■ Move a Photometric Preset light, or a Free or target light when it’s a
"practical" light within a scene (a light that appears in the scene itself).
Combine the light with a self-illuminating geometric object. If you want
to move a target type of light, select both the light and its target to animate
them together.
■ Use a
free spotlight on page 5054 when a spotlight is to move within the
scene. Free spotlights are especially intended to be animated along a path,
using a Path constraint on page 3297. Unlike target spotlights, free spotlights
can bank as they travel. Use
target spotlights on page 5051 when the light
position is fixed.
