elephand is 101% correct it used in Kursk with that cammo pattern , it's a historical skinpack after all they did not paint all vehicles /tanks in the same pattern.
FYI the problem I was having was caused by one of my UV's being outside of 0,0 to 1,1. Fixed that and then the map converted perfectly. This tool is great!
