3. Context. Why do you need to do this? We might know a better way to accomplish your goal.
I need clamp to ground to work so that I can clamp things to the ground.

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

Cesium 1.38. OSX 10.12.6. Chrome 62.0.3202.38.

Tested on Safari 11.0 as well and it seems to work. May be an issue with Chrome on OS X?


Thanks for reporting this, I’ll try and duplicate and open an issue.

To clarify this happens with the default example you provided, no code changes?



I can confirm no changes were made to the code. The point just hovers above the ground in OS X Chrome.

Got it. Looks like we’re already tracking this issue here. There’s been some activity in recent days on that issue, so hopefully a fix is coming soon! Feel free to add suggestions ot even a contribution if you have the time.
