Hi Stefan,
A vector tile may contain data for several zoom levels. But what data is
shown at which zoom level is defined by the styling, not by the data
itself. It is handled on client side, by the web (or native) tile
renderer.
The path is the same as with mercator tiles (zoomLevel/x/y):

Because I have to write :

mn() returns "" and serverLayer.GetGeomType()

And the layer serverLayer ( or a layer provide by a Memory Driver) have any
method "ChoseGeometryField" or "SetGeometryColumn" (or I have missed it).
If I call serverDataSource.GetLayerByName(&

Because I have not such table.
