14 Basics Nodes Reference Camera node For additional attributes not specified here, see camera (command) and camera (node). Auto Render Clip Plane If on, Maya automatically sets the near and far clipping planes so they enclose all objects within the camera's view. All objects render and depth precision problems are eliminated. Clipping planes are only available to the software renderer (not visible in the views). If off, the near and far clipping planes are set to the Near Clip Plane and Far Clip Plane values. Auto Render Clip Plane is on by default. In some cases you should turn off Auto Render Clip Plane: • to ensure frames rendered from previous versions of Maya exactly match frames rendered from Maya 4.5 • to limit which objects render based on their distance from the camera Film Back The Film Back attributes control the basic properties of a camera (for example, the camera's film format: 16mm, 35mm, 70mm). Film Gate Lets you select a preset camera type. Maya automatically sets the Camera Aperture, Film Aspect Ratio, and Lens Squeeze Ratio. To set these attributes individually, set Film Gate to User. The default setting is User. Camera Aperture The height and width of the camera's aperture or film back, measured in inches. The Camera Aperture determines the relationship between Focal Length and Angle of View. The default values are 1.417 and 0.945. Film Aspect Ratio The ratio of the camera aperture's width to its height. Maya automatically updates the Film Aspect Ratio (and vice versa). The valid range is 0.01 to 10. The default value is 1.5. Film Offset Vertically and horizontally offsets the resolution gate and the film gate relative to the scene. Changing the Film Offset produces a two-dimensional track. Film Offset is measured in inches. The default setting is 0. Basics 443
