From Unity, it seems that the parameters "Stereo Separation" and Stereo Convergence" don't affect anythings. At least I didn't find the code that change any proprieties in the platform libs. I tried to use OvrPlugin.ipd but it's doesn't work, always return the default ipd 64mm. it means that on gear vr the sdk lock the ipd? maybe because the hw can't change the ipd of lens?
I have also the same problem with OVRProfile.eyeHeight. I need to change it but I can't find a way
