Change Sun Light to White Light

[Gabby_Getz]

Hi @whoisstan,

Those colors are coming from the Imaged Based Lighting (IBL) (and if you’re interested in more technical details, checkout this blog post).

It’s possible to configure model.environmentMapManager to adjust the lighting on each model. There are a few options depending on the look you are going for. I’ll use this test model for comparison:

1. You could disable procedural IBL entirely:

    model.environmentMapManager.enabled =
      false;

2. You could change the ground color to a dark gray:

    model.environmentMapManager.groundColor =
      Cesium.Color.fromCssColorString("#262626");

3. You could adjust the saturation and brightness:

    model.environmentMapManager.groundColor =
      Cesium.Color.fromCssColorString("#262626");

    model.environmentMapManager.saturation = 0.1;
    model.environmentMapManager.brightness = 1.5;
