Hello，everyone.I using nginx to publish terrain and tms service.
UE version is 5.0.3, cesium version is 1.28.0.
I put the IP address " http://192.1xx.xx.xx:xx/xxx/tilemapresource.xml" into CesiumTileMapServiceRasterOverlay cesium URL.
[error] [RasterOverlayCollection.cpp:127] Tile map service XML document does not have an SRS.
How can i load it?
Well, you probably need to add an SRS element. The tilemapresource.xml file should look something like this:
https://wiki.osgeo.org/wiki/Tile_Map_Service_Specification#TileMap_Resource
What does yours look like?
Hi

XML is case sensitive. Your tags use the wrong case, so your file is invalid.
Ok,I fix it.
But it still have some error
[RasterOverlayCollection.cpp:127] Error while creating tile provider: Connection failed.
[RasterOverlayCollection.cpp:127] Tile map service XML document does not have any tilesets.
Is it add some code?

You haven’t fixed it completely yet. Please check the example I linked above carefully. At a glance, I can see TileMap, TileSets, and TileSet all still have incorrect casing.
Thanks,I am careless.
By the way. I have a problem:OSGEO:41001 is not supported.

I compared it, do I need to add code?
- Must use OSGEO:41001
- Must provide s with units-per-pixel meeting the following formula for any integral value of “n” greater than or equal to 0: units-per-pixel = 78271.516 / 2^n
- This scaling allows an initial zoom level that consists of four 256x256 pixel tiles covering the whole earth, with an of (-20037508.34, -20037508.34). Other combinations of tile size and are also possible at this scale.
I’m not familiar with OSGEO:41001 offhand, but Cesium for Unreal only supports EPSG:4326 and EPSG:3857 out of the box. You’ll need to either convert it to one of those, or modify the code to add support for more. The latter is likely to be a lot of work, unless OSGEO:41001 happens to be really similar to one of the other two!
Oh, I just Googled OSGEO:41001. Should have done that before, because apparently it’s just a deprecated name for EPSG:3857.
Ah I see where you found OSGEO:41001 in the TMS spec, now. That bit about global-mercator Must use <SRS>OSGEO:41001</SRS> is… definitely not true in the case of any of Cesium’s products, and I’m quite surprised to read it on that page. If you’re using global-mercator, your SRS should be EPSG:3857.
