Overscan
Found under the Display Options section for the camera's Attribute Editor, Overscan
lets you resize the view without changing the film gate that will render. For example, the
scene on the left in Figure 11.19 is set up with an Overscan setting of 1.3, allowing you
to see more than what will render, which is defined by the outline box. The scene on the
right in Figure 11.19 is set up with an Overscan setting of 2, which increases even more
how much you see in the camera1 panel but doesn't change the view when rendered.

scene in the cam-

much renders in the

options
You can turn the green box in the panel on
and off through the camera's Attribute Editor.
Also in the Display Options section are Display
Film Gate and Display Resolution check boxes,
shown in Figure 11.20. Ideally, these two green
boxes should align perfectly in the view
pane. If the resolution box (the solid green
line) doesn't line up with the film gate box (the
dashed green line), change your film gate selec-
tion to match the resolution's aspect ratio in the Render Settings window. A resolution of
640 × 480, for example, has an aspect ratio of 1.33, the same as the 35mm TV Projection
film gate currently selected for this scene.
Environment
In the Environment section, you'll find attributes to adjust the background color that
renders and to create an image plane as shown in Figure 11.21.
If you want to use a solid color as the camera's background when you render, click the
color swatch next to Background Color to change the background color in your renders
using the Color Chooser. The slider allows you
to control the value, or brightness, of the cur-
rent color. Neither changes the background
color of your view panels, however.
