sceneview-android: Augmented Face - Not Rendering Model and Still in "surface mode"

Hello, I was trying to understand learn and understand “sceneview” usages, I already discovered how to get Augmented face in “sceneform-android” but when I try sceneview, I encountered several problems,

• First camera settings are seems to be not working properly because some options act wrong. (For example MESH3D mode or I was able to enable Deph mode (normally I shouldn’t be able to do that in Front Camera) )
• Model size is too small
• Model moving opposite side when I move my head (If I go right, model goes left)
• Model not render properly and shows me “black material”
• I’m always seeing “Searching for surfaces…” (front camera or back camera) It should not be visible in front camera

Here my minimal code (only MainActivity)

    private lateinit var binding: ActivityMainBinding
    private val facesNodes = HashMap<AugmentedFace, AugmentedFaceNode>()
    private var faceModel: ModelRenderable? = null
    
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = ActivityMainBinding.inflate(layoutInflater)
        setContentView(binding.root)
        loadModels()

    }
    
    private fun loadModels() {

        lifecycleScope.launchWhenCreated {
            binding.sceneView.configureSession { arSession, config ->
                val filter =
                    CameraConfigFilter(arSession).setFacingDirection(CameraConfig.FacingDirection.FRONT)
                val cameraConfig = arSession.getSupportedCameraConfigs(filter)[0]
                arSession.cameraConfig = cameraConfig
                config.instantPlacementMode = Config.InstantPlacementMode.DISABLED

                config.augmentedFaceMode = Config.AugmentedFaceMode.MESH3D
                arSession.configure(config)
            }


            faceModel = loadModel(
                context = this@MainActivity,
                lifecycle = lifecycle,
                glbFileLocation = "models/fox.glb",
            )

            binding.sceneView.onAugmentedFaceUpdate = {
                val existingFaceNode = facesNodes[it]
                when (it.trackingState) {
                    TrackingState.TRACKING ->
                        if (existingFaceNode == null) {
                            val faceNode = AugmentedFaceNode(binding.sceneView.lifecycle, it)
                            val modelInstance = faceNode.setFaceRegionsRenderable(faceModel)
                            modelInstance.isShadowCaster = false
                            modelInstance.isShadowReceiver = true
                            faceNode.faceRegionsRenderable = faceModel!!
                            binding.sceneView.addChild(faceNode)
                            facesNodes[it] = faceNode
                        }
                    TrackingState.STOPPED -> {
                        if (existingFaceNode != null) {
                            binding.sceneView.removeChild(existingFaceNode)
                            facesNodes.remove(it)
                        }
                        facesNodes.remove(it)
                    }
                    else -> {
                        facesNodes.remove(it)
                    }
                }
            }

        }
    }

activity_main.xml snippet as well

    <io.github.sceneview.ar.ArSceneView
        android:id="@+id/sceneView"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

PS : I used "fox and “face” glb files from sceneform for quick testing.

If you need additional information please let me know.

Thank you.
