Renders two images as though seen from the left and right eye without modifying the camera or defining two separate animation paths. When both the Render Left and Render Right values are on, both views are rendered in the same image, either horizontally or vertically, depending on which dimension is largest.
To render both views of a 640 x 480 image, set the resolution to either 1280 x 480 or 640 x 960 in the Render Setup dialog box.
This shader can be applied directly to the camera in the lens shader stack. See Applying Lens Shaders to Cameras [Cameras and Motion Blur].
