[RESOLVED] Issue with Cesium Sun Sky hiding Earth surface

Hi there!

I am using Cesium in UE4 and I noticed that when I change the SolarTime variable in the CesiumSunSky blueprint, the other half of the world (which was previously in darkness), is now covered by atmosphere and just shows a blue ball, rather than the usual Cesium atmosphere and terrain. Although this is what I see when I play in the editor, it remains a problem when I run the program externally.

I have tried to play around with the properties of the Cesium Sun Sky blueprint but with no luck. I have attached two images to this post. One is what the Earth looks like using the default settings and the second is what the Earth looks like when I change the SolarTime by 12 hours.

Any help on this would be greatly appreciated.


Fixed the issue by changing the Transmittance Minimum Angle in the SkyAtmosphere component of CesiumSunSky from -90 to 90 degrees. Not completely sure what the side-effects of this change will be, but it allows the entire globe to be seen regardless of position of the sun.


Hope this helps someone!
