Single pass stereo rendering is rendering too dark

Yes, single-pass stereo is supported on Rift. The brightness should be the same with or without it enabled. Can you click Help > Report a Bug... in the editor and then share the case number here? I haven't been able to reproduce this on my Win10 + 970 machine. Can you attach output_log.txt from a run with the issue or a project that reproduces it?

I'm working on getting a reproducible scene that isn't our entire project (10+ GB), but in the mean time I've found that the darkness is only happening when running in the editor. When running from a build, the scene looks normal in the Rift. I also was able to test this on another machine (with different hardware) and reproduce the issue.

I'll post back a case number when I have a smaller project to submit a bug report for.

The editor sometimes uses the wrong gamma space when switching build targets. Did you recently toggle linear lighting or switch between Android and Windows?

I haven't switched build targets, but I did switch on and off a few different player settings like color space, stereo rendering method, VR SDKs, etc while testing. With that said, the issue occurred before doing any of that.

Interesting. It may help to reimport assets or re-bake lighting. It would also help to click Help > Report a Bug... to let Unity know about the issue.

I have both reimported assets (this happened when I updated to Unity 5.5.0) and rebaked lights. Unfortunately it didn't fix the issue.

I went ahead and submitted a bug report without a project attached. The case number is 859881. I was unable to create a simple scene in a new project that either reproduced the issue or showed it well enough to see it (ie I'm not sure if the new scene had the problem). Hopefully though the info I provided may help someone identify what's happening.

Hi jlink,

I have been suffering the same problem. The scene looks fine in the editor but very dark in the oculus. After much trial and error I discovered the issue was due to having a canvas with Screen Space overlay enabled in my scene. Turning off any non world space canvases  when in VR seems to solve the darkness issue. I hope that helps!

I replicated this on my end as well - thanks for replying. I'd prefer losing our screen space UI over single pass stereo when in editor if I have to choose. It would be good to get Oculus to respond confirming the bug on their end though.

I suspect it may be a Unity issue - have raised it on their forums also :)

I am also having this problem in the editor. very very dark inside the rift. I am using 5.6.0f3
