Oh , i am still trying to create vector tiles

look at this!
gagiopapinni@dell:~/marble-master/tools/vectortilecreator$ python3 vectortilecreator.py -d ~/.local/share/marble/maps/earth/vectorosm asia.txt
Creating cut out region ./japan-latest.osm.pbf.139.6561-35.5825-139.8820-35.7850.osm.o5m

in asia.txt i have this:http://download.geofabrik.de/asia/japan-latest.osm.pbf;Tokyo;139.6561;35.5825;139.8820;35.7850.It is from default asia.txt region file, so here everything is good... but what is wrong ?What is 'osmconvert' and where is it ?

See the section "Creating the tools - osmconvert and osmfilter" in https://techbase.kde.org/Projects/Marbl ... leCreation
