How to use TransformableNode in SceneView with all gestures?

TransformableNode gestures are not working on the object in SceneView.

I'm displaying a 3D object on SceneView. When I provide TransformableNode as first child to the scene of SceneView then no gesture is working. But when do the same thing with ArFragment, then everything works.

private fun createNode() {
    val transformationSystem = makeTransformationSystem()
    val transformableNode = TransformableNode(transformationSystem).apply {
        rotationController.isEnabled = true
        scaleController.isEnabled = true
        translationController.isEnabled = false // not support
        setParent(sceneView.scene)
        this.renderable = myRenderable // Build using CompletableFuture
    }

    sceneView.scene.addOnPeekTouchListener { hitTestResult, motionEvent ->
        transformationSystem.onTouch(hitTestResult, motionEvent)
    }
}

private fun makeTransformationSystem(): TransformationSystem {
    val selectionVisualizer = FootprintSelectionVisualizer()
    return TransformationSystem(resources.displayMetrics, selectionVisualizer)
}

I want my 3D object in SceneView can be able to rotate and scale using gestures which are used in TransformabelNode.

Try calling transformableNode.select() after you create your node (or simply call select() in your apply block).
