In Sandcastle, rendering transparent objects in this way causes a problem with the order. I hope the display level of the billboard and label can be higher, and the rendered image of the billboard is not consistent with my original image.

你好
你能详细解释一下你到底想要什么效果吗？
Hi @zhangyahan ,
Thanks for your post and welcome to the Cesium community.
I took a look at the sandcastle you provided and it seems what is happening is Z-fighting caused by a general transparency issue in Cesium related to Billboards and Labels. This issue has been reported in the past and we have an issue open to make a fix in the library Translucency issues with label on top of billboard · Issue #9681 · CesiumGS/cesium · GitHub
Here is one thread that covering another discussion of this issue if you are interested The problem about depth performance between label and billboard - #2 by kasatik143
Unfortunately we do not know of a workaround at the moment. I added a note about your post to the GitHub issue, feel free to add more info or upvote the issue to help us prioritize the fix.
Thanks,
Luke
