Hannah you forgot to enable terrain. Here’s your code with terrain ON and ground clamping isn’t working:

Sorry, I did enable terrain, I just didn’t include that in my code snippet. Here’s what I see:

What version of Cesium are you using, and what is your browser and operating system?

Sorry, I feel a bit stupid that I was using an old installation of Cesium. The current version fixed it. So I’m waiting for the ground clamping and rotation support of imagery layers. Thank you and let me know if there’s any way I can speed up some developments in this area.
