3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

We want to keep the camera above the terrain. The camera does snap back above the terrain, but you can get some views that look kind of bad. See attachment. Is this a known issue?

4. The Cesium version you’re using, your operating system and browser.

Hi Scott,

Yes, the is a known problem, we’re tracking in #5999. The camera is allowed to “pass through” the terrain until loading is complete, which allows these views.

There’s been a PR opened to fix, #6012, but a consensus has not yet been reached about the best way to solve the issue. If you have any input, let us know there!
