Camera Controls
These controls determine the properties of the camera "lens". If you imported an RPF or RLA file from 3ds max, you can also control how to use the file's camera animation information.
Field of ViewControls the amount of space visible through the camera. The greater the field of view, the farther away the scene appears.
Focal LengthSets the distance of the focal point. As the focal length increases, the field of view decreases and vice versa.
Aperture WidthSets the size of the camera lens opening. This affects the Field of View.
Stock LensesProvides several standard focal lengths. Click a button to set the focal length and field of view.
RPF Transform LayerSelects the layer in the composite that has camera animation you want to use. For more information, see Using Camera Animation in 3ds max RPF and RLA Files.
