AR project, Universal Render Pipeline renders blackscreen #386

Closed danbruttyo2 closed 3 years ago

danbruttyo2 commented 3 years ago

I use AR Foundation and the Universal Render Pipeline package in Unity, and it works fine when building straight from Unity, but after exporting with the flutter plugin, it displays a blackscreen. The strange thing is that planes are still detected and displayed (so AR Foundation gets the camera information), but the camera's image is not rendered.

I suspect that the Universal RP package doesn't get exported with the other packages.

Has anybody faced this problem before?

Did you follow these instructions to add an ARBackgroundRendererFeature? And if you already did, maybe try moving these files into a Resources folder instead of Rendering, to maybe force them to be included.

Haven't tested this yet, but I did run ARfoundation in URP before in flutter. I switched back because URP messed up on iOS, and don't remember what I did to set it all up.

I do remember having to add the following to proguard-user.txt in unity to deal with some camera permission issues. Not sure it is related, but it can't hurt to try.

-keep class com.unity3d.plugin.UnityAndroidPermissions** { *; }
-ignorewarnings
