Below is my code that I have been tinkering with, however, I can't seem to figure how to remove highlighting from my 3D buildings. Not sure how to go about it.

], function(Map, SceneView, SceneLayer) {

// Create Map
var map = new Map({
basemap: "dark-gray",
ground: "world-elevation"
});

// Create the SceneView
var view = new SceneView({
container: "viewDiv",
map: map,
camera: {

// Create SceneLayer and add to the map
var sceneLayer = new SceneLayer({
portalItem: {

},
popupEnabled: false
});
map.add(sceneLayer);

// Create MeshSymbol3D for symbolizing SceneLayer
var symbol = {
type: "mesh-3d", // autocasts as new MeshSymbol3D()
symbolLayers: [{
type: "fill", // autocasts as new FillSymbol3DLayer()
// If the value of material is not assigned, the default color will be grey
material: {
color: [244, 247, 134]
}
}]
};
view.on("pointer-move", function(event){
view.hitTest(event).then(function(response){
let highlight;
if (response.results[0]) {
var graphic = response.results[0].graphic;
view.whenLayerView(graphic.layer).then(function(layerView){
highlight = layerView.highlight(graphic);
})

}
})
});
// Add the renderer to sceneLayer

};
});

Check out the pointer-move listener on line 65, those functions/callbacks are where your highlight is applied.

Hi Jeremy Singh‌,

I couldn't get your code to work as its throwing error for invalid Portal ID.

However what I see missing is for you to add:

if (highlight) {
      highlight.remove();
}

That should do the trick.
