Ok thanks very much.
I understand now the process, interresting but time consumering! I think in the future a more powerful mission builder enabling zooming in, until map beeing replaced by aerial view like IL2 Fmb, will be welcomed by average user like me and experts modders like you mates.
By the way as we are speaking about maps, I have a weard phenomena on three downloaded Maps: Iran-Irak 8O's, Lybia and Falklands. In those three maps Runways, taxiways, and parkings are not showing up! all objects seems to be here... I've downloaded also Mescalero proving grounds, and in this case it's perfect!
Falklands is in a separate install, and the others in SF2 Europe. Looks like those maps search for an missing objects library not present in the stock game?
