Been doing a little bit of investigating as had a few issues with this section.
- sdk 6.0 android is great, If you have a phone running 6.0 android. I had to install 5.0.1 (Although i now cant be sure that this isnt tied into another issue)
- You need to get the gvr-unity-sdk-0.6 as they renamed to googleVR at that did not have the demo packages.
- (May be tied into number 1) Adding the VR camera can result on seeing the google outline cardboard outline and a blue screen when playing in editor and on phone, Click the Main camera,Left and right camera’s in the options you need to change them all from Solid Colour to Skybox.
- Use unity 5.3.4f1 and no higher at this time. Anything higher than this and when you change text to world space your text vanishes. This version does not do this.
I have no idea why number 3 occured but it did but was an easy fix.
