In the 0.5 integration we checked if OVRManager.isHSWDisplayed during the start menu so the user didn't accidentally press spacebar or mouseclick to dismiss the HSW and then also progress through the first start screen without meaning to. Is there an equivalent work around in Unity 5.1 with native VR support?
From what I read, SDK 0.6.0 already removed support for this as well, so it's probably not just simply hiding inside Unity 5.1 somewhere. I am guessing that this is because when Oculus launches their desktop platform store, it will just display the HSW when the user puts on the headset just like the Gear VR does and you will no longer have to worry about this for your own app.
Unless you distribute it outside the platform store, that is.
