Editor Play, Game = black screen

Just chiming in, I would really like to see someone with some knowledge address this.

Me too.

Does anyone know what the cause for the Play and black screen issue is?

This has been reported on the forum here for over a month now, with numerous SDK upgrades and fixes. Yet this problem still persists. Sometimes it can be hard to test scenes and tweak screen space effects by having to build each time, as we have no real-time DK2 feedback to test with.

For me the behavior changes at random. Sometimes I get no picture (not even black), sometimes I see it as it should be and then at other times my editor window shows it instead of the Game window and in some cases it just makes the editor window flicker like crazy.
Sometimes a Unity reboot solves it, sometimes I just ignore it and a play later suddenly switches to a more normal behavior. It's all pretty weird, but I guess it is connected with me using 2 screens and sometimes moving the game window from one screen to the other.

If I'm not mistaken there was a post about this behavior. And, if I remember correctly, it is because of a bug in the Oculus plugin. If that is the case, I assume in the editor the DLL is not using the correct swapchain. Try open multiple game views (i.e. have a popped out window and one docked) and see what happens.

All that aside, when you make a build your game works as expected, correct? If not then maybe there's a bigger issue here.

Can you guys post more information about your systems?

OS and video card and video driver would be a good start. Also Unity version. Thanks.

Happens to me with Unity 4.5.2, win 7 gtx770 latest driver. Also sometimes the game output works, but it gets rendered into the inspector tab instead of the game tab.

Win 7 Ultimate 64
GTX 670 with 340.52
Unity 4.5.2f1
SDK 0.4.2

dual monitor (2x 1680x1050, 60Hz)

Win 7 Ultimate 64
GTX 680 with 340.52
Unity 4.5.3f3
SDK 0.4.1
dual monitor (2x 1920x1080, 60Hz)
DX11

I dare not upgrade to 0.4.2 due to the horror stories of the Rift locking.

In some Unity projects with OVR, game mode works but not all the time.

Seeing this as well.

Building on the below. Have never seen this black screen issue here:
Unity 4.5.3f3
SDK 0.4.2
OS X 10.9.3
2.3 GHz i7
8GB DDR3

The black scenes appear on:
Intel Core i7 3820 (3.60GHz)
12GB DDR3
Windows 8
NVIDIA Geforce GTX 660 1.5GB

I'm wondering if rendering type is an factor too? Using forward it seems to occur more often than deferred.

Did a ton of testing on this today and I think I've found how to replicate the black screen bug.

Things that didn't work:
- Ranged Quality settings
- Updating graphics driver firmware
- Updating DX
- Update OS to latest build (Win 8.1)

The only way I can consistently replicate on my end is within player settings > Enabling 'Use Direct3d 11'. When this is checked I receive a black screen. When unchecked the scene works normally.
