I just watched the tutorial of how to download mods, but I find that you can actually select mods in the start screen of ArmA3, do I also need to do what the video tell me to after I moved the file??
also, I don't know why, my accessory mod don't work (the flip up magnifier part), I downloaded joinrail, CBA... everything the mod requires, and still it don't work. (I need to push the switch optic key or what?)
