re-render scenelayer

[JamesEyre]

I am am writing a web app builder widget, and i want to re-render a scenelayer coming from my sceneview. I set the renderer on the scenelayer, but nothing happens. Any ideas?

see the code below.

public startup() {

   this.sceneView.map.allLayers.forEach((layer: Layer) => {

       if (layer.id == "154bd77e20e-layer-16") {

         this.layerToRender = layer as SceneLayer;

      }

   });

   var symbol = new MeshSymbol3D(
      new FillSymbol3DLayer({
         material: {
            color: [244, 2, 1]
         }
      })
   );
   var renderer = new SimpleRenderer({
      symbol: symbol
   });

   this.layerToRender.renderer = renderer;

}
