How to config the elevation angle of a bipod?

[hiddenzone 2]

The default elevation angle (vertical) of a deployed rifle with official bi-pod would be about -10 ~ 10 degrees when prone, or -20 ~ 20 degrees otherwise. How to config that in 3rd-party mods?

I'm pretty sure that, unlike turning horizontally, elevating is not restricted by collision detection, since a soldier lying on the edge of a building with his upper body suspended in the air still cannot aim more than 10 degrees up or down against the platform he is lying on.

 

BTW,  the deployed bi-pod is much closer to the ground when prone, than to the objects deployed on when kneeling or standing. Is that configurable?
