Strereo Object Lens Distort Settings

Differences in camera lenses or perspective irregularities cause lens distortion that results in skewed angles. Use the settings in the Lens Distort tab to rectify or simulate these types of distortions in your stereo images.

The Lens Distort tab settings are the same as in the Object Image menu for non-stereo objects. See Lens Distort Settings.
