viewer.scene.skyAtmosphere seem not to work anymore.

Sancastle example:

var viewer = new Cesium.Viewer(‘cesiumContainer’);  
viewer.scene.skyAtmosphere.brightnessShift = -0.8;  
viewer.scene.skyAtmosphere.hueShift = 0.5;  
viewer.scene.skyAtmosphere.saturationShift = 0.5;

Nothing change

The brightness shift you’re setting means the sky atmosphere is very dark. It shows up for me if you set it to a higher number.
