14 | Basics Nodes Reference > Camera node Note Changing the Camera attribute in the Image File Output section of the Render Settings window can change the Renderable setting in a camera's Attribute Editor. Image If on (and Renderable is on), the camera creates an image file during rendering. The default setting is on. Mask If on (and Renderable is on), the camera creates a mask during rendering. A mask is an 8-bit channel (the alpha channel) in the image file that represents objects in shades of gray. Black areas represent areas where there are no objects (or fully transparent objects), and white areas represent areas where there are (solid) objects. Masks are used primarily for compositing. Note If the Image Format in the Render Settings window is not set to Maya IFF, Maya16 IFF, RLA, or one of the alpha channel enabled formats which are supported by QuickTime, the camera does not include the mask information in the alpha channel of the image file. Instead, it creates a separate mask file. See also the Render Settings chapter in the Rendering book. Depth If on (and Renderable is on), the camera creates a depth file during rendering. A depth file is a type of image file that represents the distance of objects from the camera by shades of gray. Depth files are used primarily for compositing. When on, the Depth Type attributes (next) are enabled. Depth Type Determines which objects Maya uses to create the Depth file. Closest Visible Depth Uses the closest object to the camera. When transparent objects are located in front of other objects, turn on Transparency Based Depth to ignore the transparent object. Furthest Visible Depth Most often used when a Particle Effect is occluded by an opaque object. Maya uses the Furthest Visible Depth to create a Depth file. Basics 445
