  <p>I am adding an image on vertical plane in Sceneform ARFragment. But it always get rotated. The code is working fine on horizontal plane. My code for placing images on vertical Plane is as follow:</p>
  
  <pre><code>arFragment.setOnTapArPlaneListener { hitResult: HitResult, 
                                           plane: Plane, 
                                     motionEvent: MotionEvent -&gt;
  
      if(!isOnceTapedOnSurface) {
          val anchor = hitResult.createAnchor()
          val anchorNode = AnchorNode(anchor)
          anchorNode.setParent(arFragment.arSceneView.scene)
  
          andy = TransformableNode(arFragment.transformationSystem)
  
          if(plane.type == Plane.Type.VERTICAL) {
              val anchorUp = anchorNode.up
              andy.setLookDirection(Vector3.up(), anchorUp)
          }
  
          andy.setParent(anchorNode)
          andy.renderable = andyRenderable
          andy.select()
  
          // arFragment.arSceneView.planeRenderer.isVisible = false
          isOnceTapedOnSurface = true
      }
  }
  </code></pre>
