Parameters rollout
This General Parameters rollout is displayed for standard lights. These controls
turn a light on and off, and exclude or include objects in the scene.
On the Modify panel, the General Parameters rollout also lets you control the
light’s target object and change the light from one type to another.
The General Parameters rollout also lets you turn shadow-casting on or off
for the light, and choose which type of shadow the light uses. See
Shadow
Types and Shadow Controls
on page 5117 and Shadow Parameters on page 5099.

parameter.

selected.
The light will now cast shadows when you render the scene.
