Look at the vehicles_airplane_4.pkg file in C:\Games\World_of_Warplanes\res\packages
Inside of it there's a folder structure, in vehicles\airplanes\japan\JP04_A6M you'll find it
I do find the folder, but there are just two texture files; Hangar and Premium.... and.... that's It!! .... I mean.... other nations and planes have all the complete list, this is the only one where the whole set of maps is missing, ::.
Another Issue was.... I tested my new map and just found out one of my planes showing bare metal gray, did I miss something while saving the file or while packaging it again?... Are there any special settings for the DDS Image Files?
