Hello community.
I dont really know if there is a tool like that already released, but... okay nevermind.
Here is a release of simple QPF editor.
This tool can read, edit and save QPF files. Nothing more to say
All data manipulations provided by a grid view.
There are only real ingame coordinates of props could be shown/set for QPF files. By the way, the tool save it as local coordinates for location you will work with.
There is NO errors checking if you will set wrong coordinates (that must belong to another QPF file). Do what you do only if you know what are you doing.
Enjoy!
Thanks to ismokedrow for TSP Map Editor open source release.
