Problem of almost all heavy machinery in Arma3.
Correction of an aim scale on range works. But the bullet always does not lay down in a scale cross hairs. On each heavy machinery the bullet lays down on a miscellaneous from a cross hairs of an aim scale. Some low to the left. Some it is low in the right.
It occurs at different distances to the purpose. At distant distances it is badly visible, but too occurs. Machine-gun shots repeat a problem.
How it works in Arma3. By changing the firing range bullet hit no interface with horizontal and vertical lines, according to a laser rangefinder.
At the end of the video clip all as has to be.
There is a technique where the problem is not as pronounced
The offset axis ballistic computer AI from the optical sight AI. AI does not need a grid at the sight optics. For live players should not be such ballistic displacement axis.
Especially critical look at the displacement Slamer. To hit the target, the sight axis must be higher than the target.
