And it is a fact that muzzle flashes are very rare.
Not nearly every shot fired produces a muzzle flash.
It has to do with gunpowder residues in the barrel of the gun. Those are ignited and sends out a muzzle flash.
It's different for different weapons, but since OFP is either all or nothing (Muzzle flash all the time, or no muzzle flash at all) my suggestion is no muzzle flash at all.
The reason you see huge muzzle flashes in the movies is because of the blank shots they use.
Umm...actually...
EVERY round fired
DOES produce a muzzle flash,...but you can
NOT SEE muzzle flash in daylight. It pretty much only shows up in the dark. (I dont think that is possible in OFP)
Muzzle flash has
nothing to do with powder residue in the bore. When a round is fired, the powder in the casing does
not "explode"...it
burns rapidly, causing gasses to expand, and push the projectile along down the bore. When the bullet leaves the muzzle, it is followed by the gasses that are pushing it (which are
still burning) hence producing flash.
Pretty much all modern military ball powder has "flash retardants" added
And "movie" ammo has things added to increase flash (for dramatic effect)
ANYWAY as you stated, in OFP it is either all, or none when it comes to muzzle flash...If you take it away during the day, you wont have it at night (which would be even more un-realistic)...so it is probably best left alone
