V-Ray 2 does not support stereoscopic rendering, so only monoscopic rendering is possible.

Rhino can only render stereo images with V-Ray 3+. Refer to the support article, Rhinoceros 5.0 with V-Ray 3.6 for more information 

These instructions are geared towards people who are well-versed in using both Rhino and V-Ray. These instructions are meant to help you optimize your workflow so that you can produce 360° monoscopic panoramas that work well with the Visual Vocal web portal and mobile VR application.

For information on what kinds of image files you should upload, including recommended resolutions, refer to the article, Acceptable Image Formats
