In other words, how to adjust the source code so it can allow for WMS handling along with REST for elevations models ?
Since WMS 1.3.0 the order of bbox coordinates depends on the CRS. Systems with angular coordinates like EPSG:4326 use latitude as first axis. So the BBOX should be S,W,N,E
DEFAULT_DEM_SERVER = [
("https://data.geopf.fr/wms-r/wms?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&STYLES=normal&FORMAT=image/geotiff&LAYERS=ELEVATION.ELEVATIONGRIDCOVERAGE.HIGHRES&WIDTH=5000&HEIGHT=5000&CRS=EPSG:4326&BBOX={S},{W},{N},{E}", 'Geoplateforme', 'Elevation data from IGN')
]
This url works but it miss a peace of code into _operators/io_getdem.py to correctly setup WIDTH and HEIGHT according to the target resolution of the DEM (meter/pixel).
Oh I see, I just checked and it works indeed. So you also implemented this handling of WIDTH and HEIGHT according to target resolution for the Basemap I presume? Maybe if you guide me to which line in which file you implemented it I can reproduce the same for the DEM ?
check this branch : https://github.com/domlysz/BlenderGIS/tree/wms_dem
The target res is hardcoded to 5m/pixel : https://github.com/domlysz/BlenderGIS/commit/b3e6a6a788913f3a23d4d893e9fe462a7fcbe63f
alright, cool! So the WMS version of RGE ALTI's resolution is 5m and not 1m? Also there is a max height/width of 10000 imposed by the server, what happens if the user chooses an extent bigger than 10km * 10km ?

Describe the bug
This isn't a bug but only a question that have been raised in https://github.com/domlysz/BlenderGIS/issues/158. Since it has been 5 years now I was wondering if it is now possible to import custom elevation from WMS even though it serves a 3 band geotiff (the elevation information is in the first band).
How to Reproduce
What I have been doing is trying to add the WMS GetMap request in the list named DEFAULT_DEM_SERVER of the prefs.py source code. It doesn't seem to be working which is quite anticipated.
