Aiming sights adjustment for vehicles

[Gargantua 0]

I can't get how to use zoom values for optics

Quote[/b] ]initFov=0.7; minFov=0.42; maxFov=0.8;

i guess lower values mean bigger zoom ? but i can't get big zoom even with minFov=0.01 or smth. also i'd like to know how to adjust aiming sights.

gunEnd = "e_1";

memoryPointGunnerOptics = "view_1";

this is what defines aiming in vehicles when looking down the sights. but no matter how i move these point real aim is a bit higher then optic sight itself. what's up? are there usefull hints to adjust sights ?
