Hello !  
I have installed Cesium ion addon to Unreal. I followed all steps and created a project with 3D Google tileset. When I try to open this project on a different computer the 3D map doesn’t load. There are no error messages or any other identification of what is going wrong. I debugged API key and it seems to work fine. Log message in Unreal also says that loading of the map was “done”

Can you help me solving this?

Does the sample level work on both computers? You can download the Cesium for Unreal Samples and open the `12_CesiumGoogleMapsTiles` level to check.
