You can interactively adjust the attributes of certain light sources in a view using light manipulators. Light manipulators display in scene views (or, in some cases, the light source’s view, if you look through the light source). You can move the center of interest or origin or the pivot point with the light manipulator. See Show, hide, or resize a light manipulator.
Move the two parts of the light manipulator to change the location (origin) and direction (Center Of Interest) of a light. All lights include this option.
To show the manipulator, see Show, hide, or resize a light manipulator.
Move the Pivot manipulator and then click it to change the point that a light pivots about when you move the light or the center of interest. Click the Pivot manipulator again to disable the pivot point. All lights include this option.
To show the manipulator, see Show, hide, or resize a light manipulator.
