Sorry, my English is not good
environment：C++ Project 、 UE5.5.4 、cesium for unrealv2.16.0 from FAB
step：
unreal editor works fine,Run crash after bundling
I have been troubled for a long time, please help me,thank!
@Yuan_Yao Thank you for the bug report. Do you have any further information - a log to attach or an error message? It’s hard for us to figure out what might be causing this error just from this information.
I used the first map from the CesiumforUnrealSamples project, changed “Source “from” WorldTerrain” to “FromEllipsoid”, pressed “1” to call “RefreshTileset”, and Package the project.
Crash when called the second time.
I suspect something to do with FromEllipsoid.
Do you have any solutions？Thank!
can you please share unreal engine log that would be helpfull.

@Yuan_Yao Sorry for the delaying in responding, we had a long weekend this week so I’ve only just gotten back to the office.
I was able to look in to your crash and reproduce it with the steps you’ve described. I’m still trying to figure out what’s causing it, but I’ve drafted up a GitHub issue to keep track and make sure we tackle it.
Thank you again for the bug report!
OK, thank you.
I’ve managed to track down the source of the bug, and I’ve made a pull request with a fix that you can find here. This fix will hopefully make it into the next release of Cesium for Unreal, but you can follow the developer setup to build your own copy of Cesium for Unreal with the ellipsoid-tileset-raster-unloading branch of Cesium Native if you want to get the fix now.
