Cesium3DTileset rendering when extremely close in Cesium+Webpack, any input?

1. A concise explanation of the problem you're experiencing.

Hi,
I installed cesium using webpack as instructed in this tutorial:https://cesiumjs.org/tutorials/cesium-and-webpack. But when I load a Cesium3DTileset it doesn't show up until I'm extremely close to it. I've tried tinkering with every option for the Cesium3DTileset with no avail.

2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.

import ces from 'cesium/Cesium';
require('cesium/Widgets/widgets.css');
require('./css/main.css');
let viewer = new ces.Viewer('mapContainer',
{
      timeline: false,
      animation: false,
      vrButton: true,
      sceneModePicker: false,
      projectionPicker:false,
      infoBox: false,
      selectionIndicator: false,
   // terrainProvider :new ces.EllipsoidTerrainProvider({}),
   // baseLayerPicker: false,
   // imageryProvider: false,
   // globe:false,
      scene3DOnly: true,
    }
  );

let pinBuilder = new ces.PinBuilder();
viewer.scene.globe.depthTestAgainstTerrain = false;

//tileset
let tileset = viewer.scene.primitives.add(new ces.Cesium3DTileset({
     url : '../Scene/Cesium.json'
}));
let v = viewer;
//tileset position
viewer.entities.add({
     name: 'Blank blue pin',
     position: new ces.Cartesian3.fromDegrees(lng, lat, height),
     billboard: {
       image: pinBuilder.fromColor(ces.Color.ROYALBLUE, 48).toDataURL(),
       verticalOrigin: ces.VerticalOrigin.BOTTOM
     }
   });
//testing other entities and primitives
var blueEllipse = viewer.entities.add({
    position: ces.Cartesian3.fromDegrees(-95.0, 40.0, 100000.0),
    name : 'Blue translucent, rotated, and extruded ellipse with outline',
    ellipse : {
        semiMinorAxis : 150000.0,
        semiMajorAxis : 300000.0,
        extrudedHeight : 200000.0,
        rotation : ces.Math.toRadians(45),
        material : ces.Color.BLUE.withAlpha(0.5),
        outline : true
    }
});
var outlineOnly = viewer.entities.add({
    name : 'Yellow ellipsoid outline',
    position: ces.Cartesian3.fromDegrees(-100.0, 40.0, 300000.0),
    ellipsoid : {
        radii : new ces.Cartesian3(200000.0, 200000.0, 300000.0),
        fill : false,
        outline : true,
        outlineColor : ces.Color.YELLOW,
        slicePartitions : 24,
        stackPartitions : 36
    }
});
// 1. Draw a translucent ellipse on the surface with a checkerboard pattern
var instance = new ces.GeometryInstance({
  geometry : new ces.EllipseGeometry({
      center : ces.Cartesian3.fromDegrees(-100.0, 20.0),
      semiMinorAxis : 500000.0,
      semiMajorAxis : 1000000.0,
      rotation : ces.Math.PI_OVER_FOUR,
      vertexFormat : ces.VertexFormat.POSITION_AND_ST
  }),
  id : 'object returned when this instance is picked and to get/set per-instance attributes'
});
viewer.scene.primitives.add(new ces.Primitive({
  geometryInstances : instance,
  appearance : new ces.EllipsoidSurfaceAppearance({
    material : ces.Material.fromType('Checkerboard')
  })
}));

tileset.readyPromise.then(function(tileset) {
  // viewer.scene.primitives.add(tileset);
  viewer.flyTo(tileset);
  console.log(`cargo con exito! ${tileset}`);
}).otherwise(function(error) {
  console.log(error);
});

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.
My application needs to be able to show a Cesium3DTileset from a relatively far distance.

4. The Cesium version you're using, your operating system and browser.
  cesium: "^1.49.0"
  os: Windows 10
  tested browsers:
         Chrome Version 69.0.3497.92 (Official Build) (64-bit)
         Firefox Quantum 61.0.2 (32-bit)

Does this only happen in Webpack? Can you try it with regular CesiumJS as well?

It’s hard to tell without seeing the tileset, but I can imagine this happening if your root tile is empty and the geometric error set is too small to load the child tiles until you’re close enough. See the geometric error in the spec. To debug this, you can try setting the maximumScreenSpaceError to 1 to see if that fixes it, and if so, then it is a problem with figuring out the right geometric error.
