How can I change the cesium lighting setup so the tiles appear the same zoomed in and out?

I have a sandcastle. However, a free key will be needed to make it work. The key can be obtained by going to to create a free account. Your key will then be on

The code is:

const osm = new Cesium.UrlTemplateImageryProvider({
   url : '{z}/{x}/{y}.png?key=<your  key>',

console.log( osm.url )

const viewer = new Cesium.Viewer("cesiumContainer", {
  baseLayer: Cesium.ImageryLayer.fromProviderAsync(osm),
  baseLayerPicker: false,
  geocoder: false,
  animation: false,
  timeline: false,
  infoBox: false,
  homeButton: true,
  fullscreenButton: false,
  sceneModePicker: false,
  selectionIndicator: false,
  navigationHelpButton: false,
  terrainProvider: null,
  creditContainer: document.createElement('none'),

The image this produces when zoomed out is:


There is a light blue tint to the globe, which I don’t want. However, if I zoom in, I see:


which matches the tile set I am using (CH swisstopo LBM Dark).

I figure there is something about the lighting that needs to be changed so zoomed out will look the same as zoomed in, but I am not sure how to do that…?

(I want the dark zoomed in look, not the light blue when zoomed out)

[UPDATE 1] What has gotten me a bit closer is setting:

viewer.scene.globe.atmosphereLightIntensity = 0

which then results in the zoomed out image:

instead of a light blue, it is a light gray.

There is the bluish ring around the globe which needs to go away as well.

So, the answer appears to be to set:

viewer.scene.globe.showGroundAtmosphere = false;

This provides the zoomed out image of:

And zooming in no longer shows a distinct color shift with the drawn tiles.

There is still that blue ring around the globe that I would like to get rid of…?

Hi there,

The atmosphere is what making the imagery appear blue. You can disable it by setting scene.globe.showGroundAtmosphere to false.

Thanks. I did that and it worked. I am still getting the blue ring. Any way to get rid of it?

That’s the sky atmosphere, which can be disabled by setting to false.
