Currently the point that characters look at is a point at infinity, straight away from their face: this results in soldiers with their guns up on target staring onto the ground five meters in front of them.
Please make the eyes of a character move around, and focus on the point they are looking/aiming at. (But don't make them move unrestrained and instantaneously as in arma 2, so they rotate 180 around in the characters head as he turns it)
Especially when characters are talking to each other, or inside vehicles, them looking at each other occasionally would do much to the immersion. Right now everybody behaves as if they're just staring into space. {F22783} {F22784}
