Use Stereo cameras to create three dimensional renders with the illusion of a three dimensional depth of field. When rendering a stereo scene, MotionBuilder takes into account all of the Stereo camera attributes, and performs calculations to produce an anaglyph or parallel image that can be composited by another program.
Once you add Stereo camera to a scene, three cameras are listed below the Camera switcher in the Cameras folder. See Creating a stereo camera.
