I'm trying to build a scene for android gear vr in unity3d. But what resolution i set for that scene default is Free Aspect, and galaxy s6 has a total resolution 2560x1440. So what is targeted resolution for this device. Second i downloaded a ovr_sdk_mobile_1.0.4 from oculus site but how can i use this sdk with unity3d? This rar files doesn't have any unity packages or samples so what is that for?
I didn't set anything, so I think whatever the default is may work. Also different devices have different resolutions but you don't need to worry about that in Unity, the Oculus runtime must handle it. Have you tried just running your app?
I believe the resolution is controller through "vrsettings.renderscale" or something like that.
