I am looking for a way to pre-generate raster tiles from a QGIS project. I need the tiles themselves to be created in EPSG:4326 CRS. The QGIS project contains a lot of vector layers with complex symbology which is also scale dependent so export the QML to SLD files is not an option. After the tiles creation I need to serve the tiles through WMTS in EPSG:4326 tile matrix (prefer using QGIS Server). Finally the client needs to display the tiles in EPSG:4326 without any special installation and without re-projection of the tiles.
