The camera navigation buttons
The Camera and Light view navigation buttons
are the s ame with a few exceptions. The buttons
are visible when a viewport with a Camera or
Light view is active. The Camera and Light view
navigation buttons do more than adjust your view.
They tr ansform and change the parameters of the
associated camera or light object.

treated the same as the camera field of v iew.
Keep in mind the following:
•UsingtheCameraandLightviewport

rotat ing the camera or Light, or changing t heir
base p arameters.
• Changes made with Camera or Light view

as other object changes.

The field of view defines the width of your view as
an angle with its apex at eye level and the ends at

exactly like changing the lens on a camera. As the

the perspective becomes distorted, simi lar to using

see less of your scene and the perspective flattens,
similar to using a telephoto lens. See Cameras
(page 2–1365).
Click Light Hotspot (page 3–752) for a light
viewport to achieve the same effect as zooming.
The hotspot is the inner of the two circles or
rectangles visible in a light viewport. Objects
insidethehotspotareilluminatedwiththe
full intensity of the light. Objects between the
hotspot and falloff are illuminated with decreasing
intensity as objects approach the falloff boundary.
