well, I did not try hillshade in any other case yet, so, yes. > Have you chosen the correct a factor value? What is that?

The project is set to EPSG:6670, and the Raster layer is not projected on the fly, but from a file that is in EPSG:6670. So I think, reprojection is not the problem here. Thanks for checking this up, if you have an explanation about the factor value, that might help. Best, Maria Shinoto > > Nicolas Cadieux > Ça va bien aller! > >> Le 13 mai 2020 à 04:31, Priv.-Doz.
