How do i create a new mapset from QGIS 3.2 for GRASS?
I can´t find the Plugin GRASS in manage and install plugins...
You need to run the QGIS 3.2.0 Desktop with GRASS 7.4.1.exe file to load GRASS with QGIS.
If using Windows, you can find this in
Start > All Programs > QGIS 3.2 > QGIS 3.2.0 Desktop with GRASS 7.4.1
