3D Tiles render as a flat white mass with no edges

• Every face is almost #ffffff, with barely any brightness difference between side and top faces.
• No window frames or floor lines are visible even at street level.
• The scene looks identical whether globe lighting is on or off, which hides the real cause.

1. Set tileset.enableLighting to false and see whether the white darkens and edges appear.
2. Hide all imagery and set scene.globe.baseColor to dark grey to confirm the model is not lost against the basemap.
3. Log the tileset.properties keys to see which batch table fields exist, such as height, floors or use.
4. Toggle viewer.scene.globe.show to false to separate a contrast problem from a placement problem.

Pass enableLighting: false with maximumScreenSpaceError: 8 to Cesium3DTileset.fromUrl, or colour by a batch table field through Cesium3DTileStyle conditions on the height property. Set colorBlendMode to Cesium3DTilesetColorBlendMode.REPLACE when ambient light washes the colour out again.

var tileset = await Cesium.Cesium3DTileset.fromUrl('/data/buildings/tileset.json');
viewer.scene.primitives.add(tileset);

tileset.readyPromise.then(function () {
  var names = tileset.properties && Object.keys(tileset.properties);
  console.log('batch table 字段：', names);
});

var tileset = await Cesium.Cesium3DTileset.fromUrl('/data/buildings/tileset.json', {
  enableLighting: false,
  maximumScreenSpaceError: 8
});

• Referencing a batch table field that does not exist: the style silently keeps the default colour and reports nothing.
• Leaving globe.show true and blaming the tileset when the model was merely invisible against a white background.
