The fsize of the flag can be any size of multiples of 2 , u need to experiment ot get the correct proportion for when the flag is ingame.. (from experience)
If you are oging to use them universally for other missions, create a folder named "Flags" in ur OFP directory,,,
To get the flag textures ingame, use
this setFlagTexture "..Flags\nameofflagpic.extensions"its either ...Flags, ..Flags or just Flags
not sure which one sorry.
extensions is the extensiont hat the flag picture is saved as. (JPEG, PAA etc)
nameofflagpic is the name of the flag in the flag folder.
Hope this helps
Rhys
EDIT: - No problem mate
