AR camera stays black with Unity 2018.2 (Android, Editor)

Question

Hello There,

I built an existing  project created with Unity 1018.1 and tried to build it - unmodified - with Unity 2018.2 which was just released.

When running in the Editor on osx the screen stays black while the webcam indicator is switched on. There are no error or even warning messages in the console.

On Android the same happens; black screen, no obvious warnings.

How can this be fixed?

Is there anything I can do to test this further?

Answer 1

PlayerSetting ： OpenGLES2

Comments

Yes that was the first thing I checked (and indeed had to change) but didn't work.

Some more observations:

Unity 2018.1.7f1 still works, there is some change specific for the 2018.2 upgrade.

The problem has to do with the "realityPlane" and/or the associated script / dll as this stays completely black when the camera switches on. All other info messages still show in the console (loading of trackables etc).

I have the same problem once I update to unity 2018.2.0f2 from 2017 version.
Now the tracking works but theres no background camera feed showing in the screen.
Have you find a solution?

I encounter the same issue. Work fine on 2018.1.8f and on 2018.2.0f2 the video background is not rendered (But recognition works).

I have got the same issue, I am on Unity Version 2018.2.0f2.

The current version of EasyAR does not support Unity 2018.2

Answer 2

There was this in Release Notes of Unity version 2018.2.0:

Android: WebCamTexture is implemented using android.hardware.camera2 package for devices which support API level 21

I suspect this change causing issue with EasyAR using webcam and result a black camera.

The last version before that (2018.1.9) works well.

Comments

Correct; I noticed that... however, with other projects the WebCamTexture works almost flawless (apart from a minor issue on Android when shutting down).

Also this affects the Editor as well so I'm afraid this issue is caused by something else.

An official response from EasyAR would be highly appreciated!

I have same problem since upgrading Unity. Some sort of official response would be good as I have to use latest version of Unity which fixes a prefab instantiation bug. At the moment I am dead in the water without a fix

---

I submitted this question again and also sent a direct email to support@easyar.com and got this non committal  response

Hi，

This is a known problem. Thank you for your feedback. We're making plans to fix it.

Thanks

is there any update on this issue?

Thanks

Did anyone ever have any luck with this?

I am running the latest versions of Unity  (2018.2.12f1) and EasyAR and am still getting a black screen, instead of the camera view, when running it on my Android device.

I disabled/enabled the PlayerSetting ： OpenGLES2 setting with no luck either.

Any help appreciated.

Thanks,  Simon

Thanks

EasyAR SDK 2.3.0/2.2.1 have been released. They are compatible with Unity 2018. You can get it from EasyAR website. You may need to refresh the webpage if you didn't see them.

Additional For MacOS, because Unity 2018 use Metal by default, you may also need to change the settings to use OpenGL Core. Look at Unity title bar and make sure there is OpenGL instead of Metal.

BTW, we are working on a perfect solution in EasyAR SDK 3.0, which will use the most of Unity features instead of a custom renderer. We will make the whole EasyAR Unity Plugin open source.

Big thanks) New version of SDK helped me.
Unity3D 2018.2.13f1

Im developing on MacOS, i'm still on Unity 2018.2.12f1, with the latest SDK 2.3.0, I'm still have the black screen, with no video display. I've already set the GPU to OpenGLCore, but still the same issue.

pls help i am using unity 2018.1 and EasyAR 2.3 still black screen on my android can some one help me on this many thanks

Please look at the logs tagged with Unity and EasyAR using commandline logcat or Android Studio to see if anything unusual happens.
EasyAR SDK 3 has been released for a while and eliminated the dependency on OpenGL, maybe you want to try that first.
By the way, try samples first. They should work.

That is probably not the error itself. There should be more lines.
Before continue report errors, did you try to run a Unity only project? And did you try samples? And did you use an uncommon Unity setting?
