Stereo camera and Oculus

Hello, I've searched for a solution to my problem, but could not find anything related.

With patch 5.1, we don't need to create 2 independent cameras for the Oculus, but on the other hand, I Don't know how to make independent rendering for each eye.

My problem is that I am using images from a stereo camera (for an ROV). Now I am not sure what would be the best solution withouth independent culling masks for each eye.

Thanks a lot =)
