Dear Support,
i added a cesium3dTileSet, changed from ion to url, gave localhost:8000/layer.json for the terrain, then add a component TmsRasterOverlay, the url is localhost:7000/tilemapresource.xml.
the log on both ports is showing that cesium for unreal is requesting terrain and imagery tiles and it is serving them. when i also change the camera also other request and reponse appear which means my camera and georeference is on the right (lat, lon).
the problem is: Terrain is not showing in the editor and imagery tiles are not showing also, althought the localserver is returning them in response.
