Camera Mode – Specifies the type of camera to use for rendering. The cameras in V-Ray generally define the rays that are cast into the scene, which essentially is how the scene is projected onto the screen. V-Ray supports several camera types:
Standard Camera – A traditional pinhole camera. VR Spherical Panorama –Spherical camera with independent horizontal and vertical FOV selection that is useful for generating latlong images for spherical VR use. VR Cubemap – A variant of the Box camera with the cube sides arranged in a single row. Unlike the Box camera's output, Cube6x1 does not produce an empty space in the output image and is useful in generating cubic VR output.
Stereo – Enables or disables the Stereoscopic rendering mode. Stereoscopic images will be rendered Side-by-side or Top-bottom based on the Output Layout option. You do not need to re-adjust the image resolution as it will adapt automatically.
