"What does "gunnerCanSee = 1+16+4+8;" do?"
after a quick google search, I found on this thread : http://www.ofpec.com/index.p....g_id%25
Basically, if you have these values :
#define CanSeeRadar 1
#define CanSeeEye 2
#define CanSeeOptics 4
#define CanSeeEar 8
#define CanSeeCompass 16
then gunnerCanSee = 1+16+4+8 means the gunner can see radar, compass, optics and ear
"And what is the "irScanToEyeFactor" ?"

Great mod by the way!
