Is there any in the year 2019 working plugin? I try QTiles but this make errors (https://github.com/nextgis/QTiles/issues/100). So I need an alternative that is working with QGIS 3.6 How I can produce tiles from maps I produce with QGIS? On Windows, if possible without any scripting.
Open the QGIS 3x change log (in my case 3.8).
https://qgis.org/en/site/forusers/visualchangelog38/#feature-generate-raster-xyz-tiles You should have the Qtiles option in the Processing toolbox.
You don't need a plugin it's a native feature of QGIS save as geopackage or Mbtiles (both are SQLITE) if you want folder of tiles just use python mbutil or others to extract. There is also GDAL2TILES_parallel.py give it a TIf makes folder of tiles. You can still download QGIS 2.18x And use the plugins that have not migrated to 3x. QGIS-LTR is now at 3x.
