Sublevels are a bit broken in Cesium for Unreal, but we’re working on a replacement system. It’s not yet merged into main, but if you’d like, you can check out the PR on Github and see if it fixes your crash.

Janine is right that we’re in the process of overhauling sub-levels. I still wouldn’t expect an access violation, though. Can you reproduce that problem in the Cesium for Unreal Samples project (especially level 4, which uses sub-levels)?

I get it work.I find my collaborator fail to save all levels in a folder.Thanks for your help.I’ll also have a view on the new method.
