CesiumJS tutorial will show buildings but not the map

I’m new to Cesium and I’m trying the CesiumJS tutorial. I created a webpage using the provided code, but when I try to run it, I see only the buildings against a black sky - no terrain. I’ve tried 3 different browsers with the same result each time. I’ve provided an image below. Everything looks fine in Sandcastle, just not when I bring up my own html file. Does anyone have any suggestions as to what I can try?


Thanks for reporting this. It’s been reported previously and we’re tracking it in GitHub. We’re currently taking a look. In the meantime, you can try using a method other than the CDN to import CesiumJS in your application.
