Can’t see terrain after standalone exe build

After building my unreal project as a stand-alone package exe, nothing from cesium shows up when I open the file. It works fine in editor mode, but in the built exe It’s just missing. Any ideas what to do to make it show up?

Hmm, not sure what would cause that. Do you get the same behavior with the Cesium for Unreal Samples project, or only with your own project?
