https://t0.tianditu.gov.cn/img_w/wmts?SERVICE=WMTS&REQUEST=GetTile&VERSION=1.0.0&LAYER=img&STYLE=default&TILEMATRIXSET=w&FORMAT=tiles&TILEMATRIX={z}&TILEROW={y}&TILECOL={x}&tk=。For this string of map service addresses, I want to fill them into the CesiumWebMapTileServiceRasterOverlay script of Cesium For Unity. How should I fill in each field?
@jh007 Thanks for the question! If I understand the service you’re trying to access correctly, you should be able to use the Web Map Tile Service Raster Overlay with the URL set to http://t0.tianditu.gov.cn/img_w/wmts?tk=<your key here> (you should replace <your key here> with the value of tk, which I didn’t want to include in my reply as you probably shouldn’t make your access key public! I would suggest removing it from your post as well 
). You can set layer to img, style to default, and tileMatrixSetID to w. This should be all the parameters required to get this WMTS service loading in Cesium for Unity!
