Sorry for the delay. Yes, I have already solved it. The problem is specific to TianDiTu Map service. I think somehow the TianDiTu Server needs to confirm the request is from browser. I made some changes on the files CesiumWebMapTileServiceRasterOverlay.h and CesiumWebMapTileServiceRasterOverlay.cpp to add Header to the request. Then I made some settings in Cesium for Unreal WMTS RasterOverlay. And it worked. See the details below.
- The change to CesiumWebMapTileServiceRasterOverlay.h
- The change to CesiumWebMapTileServiceRasterOverlay.cpp
- The settings in Cesium for Unreal depend on which url is filled. The following is just an example for Longitude and latitude projection. The WebMercatorProjection is different and simple.
