I'm currently trying to work with the Google Cardboard. I'm creating an app that will have a Side-By-Side screen like in this video : https://www.youtube.com/watch?v=cxUv8Pwdl9A&index=1&list=LLBicgV-jSgBElridAxgvF2Q
I have the latest Vuforia SDK (but not the beta for Digital Eyewear SDK).
For now, I succes to reduce the rendering to the left side of the screen as you can see in the picture in attachments.
Thanks in advance
