sceneform-intro | Sceneform is a high level 3D rendering API for Android

I added a feature based on the Codelabs tutorial from Google (https://codelabs.developers.google.com/codelabs/sceneform-intro/index.html?index=..%2F..index#15) which allows users to take photos of AR objects that were added into the scene. The code works fine, however, I wish to hide the PlaneRenderer (the white dots that appear when ARCore detects a surface) in the photo taken by users.

In the onClickListener for the "Capture Photo" button, I tried setting PlaneRenderer to invisible before the takePhoto() is called. This hid the PlaneRenderer on screen, but not in the photo captured.

This is my onClickListener:

I'm designing a Augmented Reality Android application using Sceneform. It should be able to take a photo shot with the virtual 3D objects and the physical environment, but the application keeps on crashing. I created a class WritingArFragment in Java and reference it in a fragment, but it's not working.

It says the Class WritingArFragment is never used. For example, when I change android:name="fully.qualified.class.name.WritingArFragment" to android:name="com.google.ar.sceneform.ux.ArFragment"

it works, but when I leave it as fully.qualified.class.name.WritingArFragment", it always crashes.

I want the application to take a photo of the AR environment together with 3D objects without crashing.

I was following the Sceneform Tutorials from

I have loaded a 3D object using Sceneform in Android app. I enabled AR core and used fragment as Google Developers ARCore example

Now I need to change that loaded object color at runtime when a button is clicked.

Thank you in advance for your help.
