I have used the GRASS v.to.rast and r.surf.contour functions in the processing toolbox of QGIS 3.10.13 to generate DTM raster layers from some vector contour layers. However, the DTM layers are flagged as "Temporary layer only!", and QGIS warns that they "will be discarded after closing QGIS". How do I save them as permanent layers in the current project? I'm new to QGIS so it's possible I've missed something obvious, but I've looked everywhere in the software, along with Google and stackoverflow, with no luck so far. Thanks!
