I am trying to use the VRM tool in QGIS of the SAGA package. Every time I get an error message:
layers could not be generated.
I tried different input rasters (DEM and DTM) and kept other settings at default.
I do not understand what prevents a successful execution. Does someone understand from the corresponding processing message? (posted below).
