ArmA 3, Config, Missions, 3D Modeling, Scripting, Terrain, Texturing, Tools

Mission name wont show up, I can only see mission directory instead of the name I wrote into mission editor, howto fix?

That is because ArmA 3 only searches the first 4KB of a unbinarized mission.sqm for your briefingName. To workaround it you can cheat and edit your mission.sqm and put your briefingName at the start.

mission.sqm:

version=54;
briefingName="My Mission Name";

It is also good idea to write mission name to description.ext:

briefingName = "My Mission Name";
