I haven't been able to find the answer to this anywhere (correct me if it's out there). I noticed that on the Oculus SDK page ( https://developer.oculus.com/downloads/#sdk=any
), there is 1. an SDK for Unity (i.e. Rift), and 2. an SDK for mobile (Gear VR) which also contains a Unity package.
It looks like the files for each SDK differ considerably, but I'm not sure if that is because the version numbers differ (0.4.4-beta vs 0.4.1), or because the SDKs are incompatible.
Are they compatible? If not, then it kind of defeats the purpose of using a multi-platform engine (I am trying to build to Rift and to Gear VR with the same project).
