ArmA 3 Campaign description.ext
This following inside every mission class is not necessary:
briefingName = "Mission Name"; author = "Snake Man"; overviewText = "Campaign mission overview";
Because these values are read from the mission description.ext instead.
When you are creating your ArmA 3 campaign and if you get this error:
Warning Message: No entry 'Campaigns\<NAME>\description.ext/Campaign.briefingName'.
You need to add one line in description.ext file:
briefingName = "My Campaign!";
And its fixed.
You can put other mission description.ext class entries into campaign description.ext instead. For example CfgDebriefing and CfgCommunicationMenu.
