We recently observed that when running a UE application containing CesiumForUnreal plugin, if the directory containing the UE app does not have write permission for the user then there’s a Fatal Crash. This only happens when trying to use the CesiumForUnreal plugin. The app is able to run fine if the plugin features are not accessed. Does the CesiumForUnreal plugin require the UE app directory to be writable? And if so, are there workarounds for allowing the app to run in cases where the app directory is read-only?
