Kennel;
I'm in the middle of creating a DCG coop campaign using HSFX and the WF44 map. I found out pretty early that two key files that DCG needs is;
class.dcg, and
payloads.dcg
Those two files (someone will correct me if I'm wrong) provide DCG with the parameters of all the aircraft. If they are 'old' or out of date compared to the actual aircraft available in game version you're using (e.g. HSFX) then DCG will crap out. Additionally if a skin file is not available for an aircraft you are using, DCG will also crap out.
For example, in my initial .mis master file I used the L-5 Stinson but something isn't right in one of the files because I get an error message when trying to generate a mission. I swapped out the Stinson for a Spitfire and then it was good to go.
If the class and payload files don't match the aircraft 'list' in the game then you can get a situation where your generated mission starts and every aircraft (I mean everything) blows up upon spawning. Frustrating at first but funny too.
I've literally just gone through the above scenarios. I've still can't get the Stinson into the game yet but nothing is blowing up so it's all good, LOL.
