The selectionName that lineIntersectsSurfaces returns is incorrect, and inconsistent with the one returned by intersect command.
That's because the returned name is the topmost parent of the bone.
Edit: After more tests it seems that it only happens in some cases. I'm not sure exactly when.
apc = createSimpleObject ["a3\armor_f_beta\apc_wheeled_01\apc_wheeled_01_cannon_f.p3d", player modelToWorldWorld [0, 10, 3], true]; apc animate ["poklop_gunner", 1, true];
onEachFrame {
_p1 = AGLToASL positionCameraToWorld [0,0,0];

lineIntersectsSurfaces [_p1, _p2, objNull, objNull, true, 1, "FIRE", "NONE"] apply {

};
};

}our stuff thing, returns name of all selections that were found.
In this case otocvez AND poklop_gunner, but it returns only the first one.
If we return the last one we would return the correct one here.
