The feature for defining different eye points based on the zeroing setting is a very nice feature, BUT there is a serious error with it. The result of this error is that it is basically impossible to set up properly aligned sights, that work and look correct, unless you spend an unjustifiably huge amount of time to trial and error every single zeroing position and apropriate sight animation to match.
The error is that there is a position / translation offset ,which increases with increasing view angle in relation to the gun muzzle (defined by the eye points). The angle itself matches the defined one well, but the camera offset breaks the system.
So for example when defined in the config as this
```
discretedistance[] = {50,100,150,200,250,300,350,400,440};
discreteDistanceCameraPoint[] = {"eye_50", "eye_100", "eye_150", "eye_200", "eye_250", "eye_300", "eye_350", "eye_400", "eye_440"};
cameraDir = "eye_lookat";
```
and with a memory point set up like this:

(Grey and blue parts are the adjustable, rotating sight, which rotates around a point identical to the "eye_lookat" point; Purple represents the barrel)
Now in theory the sight line (green), when the sight is rotated will always be exactly lined up with the matching discrete eye point pair, keeping the sight perfectly aligned on the screen. In practice this doesnt work at all. The angle is correct, as said, but the position of the camera gets moved in relation to the weapon's body, as shown in this picture series of my example:
[[ https://abload.de/img/look_at_bullshitlwsmw.png | Ingame Example ]]
In this picture the center of the screen is the little white dot (marked by pink arrow on the most left picture in the series). Notice how the sight, in relation to the center of the screen moves when changing the zeroing setting. The cyan part is the rear sight piece, the orange piece is the front sight piece. They are never aligned properly due to the offset. The other little boxes are just to confirm that the animation of the sight is working exactly as i defined (and matched with the multiple eye points).
Even for sights that use a reddot (and therefore get around having to align the sight animation precisely) , the translation makes it so that the defined angle becomes useless, as the aim will be higher/lower due to the heigth offset of the aimpoint.
