So I'm upgrading to 5.1 but have decided to use 5.1 with the OVR Mobile 6.0.1. SDK. Unity's native VR mode doesn't seem fully baked yet.
But one thing I've noticed is there doesn't seem to be a way to get the double barrel distorted view in the editor anymore when using the latest CameraRig prefab.
I find the distorted views useful for working on monoscopic effects and occasionally trying to determine where stuff is in my peripheral vision when working in the editor without a device attached.
Is there a way to re-enable the double barrel distortion view, or is this not an option anymore?
We removed the post-distortion preview from the editor in Unity's first-party VR support. This is really part of the display pipeline and we felt it was more useful to show you the content you rendered in the Game view and main monitor preview. If you are willing to write a plugin, it's possible to get the old distorted mirror image using ovrHmd_CreateMirrorTextureD3D11(..). However, the current preview can show everything you've rendered. It may be panning and scanning parts of the edge out of view, but you can see it all if you resize your game view to match the aspect ratio of the eye texture.
If you're using the legacy Oculus integration, it should still be showing the post-distortion mirror image. If it isn't, the app probably isn't using VR because you haven't installed the latest runtime yet. Please visit https://developer.oculus.com/downloads/ for that.
