Adjust a spot light beam

To get a good view of the area illuminated by a spot light

1. Select the spot light in the scene, or in the Outliner.
2. From the Panel menus, select Panels > Look Through Selected.
   

   This represents the view from the spot light, with the green circle representing the light cone boundary. Objects outside the circle are not lit by this spot light.

   Camera tracking, tumbling, or dollying work well in this view to help shine the spot light exactly on the desired area.

To adjust the position and angle of the spot light beam

Aside from moving the light (Position lights) and adjusting the light parameters (Adjust light source attributes), you can also adjust the spot light in the following ways:

• Move the Cone Radius of a spot light
• Move the Decay regions of a spot light
• Move the Penumbra Radius of a spot light
• Move barn doors (shutters) of a spot light
