Nested portalscene content is shown outside of portalscene?

[0megaD]

I have a portal (portal 1) (a rectangle with a transparent cover in the middle, which shows the portalscene) at -0.5f in front of me.

I have a portal (portal 2) (same rectangle shape) inside the portalscene of the first portal, located at +0.5f behind me.

If I look around in the ''real world'' I only see portal 1. If I look around inside portal 1 I can find portal 2.

However, if I position myself so that portal 2 is behind portal 1 while I'm in the portal 1 portalscene, I can see portal2 inside the real world. (It does not get cropped out of the view into the ''real world'')

I will add images and code later to expand if necessary. It may be due to user error, but as the documentation is kind of lacking for Portals I've been trying to figure it out on my own. :p

Hi @0megaD,

Thanks for trying out the platform and reporting the issue!

This does look like an issue with our platform (and not your error). We'll log a bug in our backlog and look to get it out in a future release.

Let us know if you have any other questions,

Andy

  }

  /*

  */
  private static class ARSceneListener implements ARScene.Listener {
    private WeakReference<Activity> mCurrentActivityWeak;

    public ARSceneListener(Activity activity, View rootView) {
      mCurrentActivityWeak = new WeakReference<Activity>(activity);
    }

    @Override public void onTrackingInitialized() {
      Activity activity = mCurrentActivityWeak.get();
      if (activity == null) {
        return;
      }

      TextView initText = (TextView) activity.findViewById(R.id.initText);
      initText.setText("AR is initialized.");
    }

    @Override public void onAmbientLightUpdate(float v, float v1) {

    }

    @Override public void onAnchorFound(ARAnchor arAnchor, ARNode arNode) {

    }

    @Override public void onAnchorRemoved(ARAnchor arAnchor, ARNode arNode) {

    }

    @Override public void onAnchorUpdated(ARAnchor arAnchor, ARNode arNode) {

    }
  }
}

I have to used above code for portal scene but it's not working properly.
