I use Cesium in Unreal to visualize heavy marine construction projects on the water.
I had a project in Cesium I made in Oct 2024 that was working as expected but in December I loaded it again and the map tiles were floating 20ft off the terrain. I thought at first it was a Cesium issue but I actually see the error on google maps 3D too:
You can see all the trees along the waters edge are floating about 20ft above where they should be. I experience the exact same issue in Cesium too.
Unfortunately it has made using Cesium with google for my use case unusable.
Is Cesium aware of this issue? I filed a bug report with Google last week but they haven’t responded and I doubt they ever will. Maybe there is a chance Cesium has a contact at Google Map Tiles API that could look into this.
