Hi,

Use this:

sceneform-android/core/src/main/java/com/google/ar/sceneform/Scene.java

Lines 138 to 149 in 4bdb114

	/**
	* Adds a listener that will be called before the {@link Scene.OnTouchListener} is invoked. This
	* is invoked even if the gesture was consumed, making it possible to observe all motion events
	* dispatched to the scene. This is called even if the touch is not over a node, in which case
	* {@link HitTestResult#getNode()} will be null. The listeners will be called in the order in
	* which they were added.
	*
	* @param onPeekTouchListener the peek touch listener to add
	*/
	public void addOnPeekTouchListener(OnPeekTouchListener onPeekTouchListener) {
	touchEventSystem.addOnPeekTouchListener(onPeekTouchListener);
	}

HitTestResult contains the touched node, the distance and position of the peek.

I tried it, but it doesn't work. I have two cartoon characters in a glb file. I can't get the different returns when I click on the two people. Their results are always the same.

You will soon have access to the glTF picked sub-entity thanks to the new Filament Pick API but that will be only available on SceneView (not Sceneform)
