Left eye not rendering when setting Direct Render flag to false - iOS / Cardboard SDK
I'm trying to apply filters to my Cardboard cameras to achieve blur effects etc.
Applying the effects whilst Direct Render is turned on (default) causes one image to be rendered across both eyes. I've read a couple of posts suggesting to turn off Direct Render to fix the issue.
This works great for Android and renders perfectly. However, on iOS I'm just getting one eye rendered correctly, and the other is just black (see attached).
I've searched high and low and can only find brief references to similar problems. Is this a general bug, or something odd in my set up? Anyone got any ideas? It's driving me mad.
Unity 5.3.1f1 Personal
Cardboard SDK v0.6
iPhone 6 running iOS 9
Xcode 7.2
Can you specify your effect setup (which effects, settings, etc)? I can try to replicate locally to figure this out.
The effects seem to make no difference - simply turning off direct render, even on the totally default Cardboard SD$$anonymous$$ demoScene, give me the same, single eye result.
Are there any other settings other than those set in Cardboard (maybe something in Unity itself) I can give you from my set up that might help?
I would massively appreciate any help
O$$anonymous$$, I was able to reproduce this. It appears to be related to $$anonymous$$etal. If I switch the Graphics API to Open GL (via Player Settings), then it doesn't happen. So that may be a workaround for the time being. The root cause still has to be deter$$anonymous$$ed...
Thanks so much for taking the time to figure that out. I ran a quick build last night and switching the Graphics API has indeed solved the issue for now.
We're building an app to help families and friends of blind people to understand their condition. This was a big blocker to the feasibility of the project so not only have you helped me, you've potentially helped thousands of people all over the world :) Good guy, @dolims
I am experiencing the same issue, Unity 5.2.2, Cardboard SDK 0.5.2, iPhone 6 and iOS 9.
Turning off Direct Render and HDR on Left and Right Camera causes only right eye to render. Switching to OpenGL does fix it for me as well, but FPS hit leaves that as undesirable.
I found a workaround that may be another option for you depending on which image effect you're using. Under your Cardboard object -> StereoRender->PostRender, you are able to add image effects to this ins$$anonymous$$d of the individual right and left cameras. Turn back on the direct render. I got this to work with the bloom effect... I wasn't able to use the higher thresholds that you get with HDR but I don't have a lot of white in my scene so was able to use complex mode and limit it to just that color. I couldn't attach an image so there's a pic here:
I had similar problem. I used Bloom Image Effect, 0.7 Cardboard SDK version and Unity 5.3.4f1. Only turning off "Multithreaded Rendering" in Player settings worked for me.
I had the same issue, using blur effect with 'Multithreaded rendering' setting enabled caused only one camera to render. Upgrading to Unity 5.4.0f2 solved the problem.
