Steps

1. Open 3DEN editor.
2. Place down the object "Weapon_hgun_Rook40_F" in any rotation.
3. Copy yaw, pitch, roll values from the attributes menu. Remember Z = yaw, X = pitch, Y = roll.
4. Run the following script with above values,

private _yaw = 0;
private _pitch = 0;
private _roll = 0;

private _object = "Land_PipeWall_concretel_8m_F" createVehicleLocal [0, 0, 0];
_object setPos ((screenToWorld[0.5, 0.5]) vectorAdd [0, 0, 1]);

private _vectorDirAndUp = [nil, -_yaw, -_pitch, -_roll] call BIS_fnc_transformVectorDirAndUp;
_object setVectorDirAndUp _vectorDirAndUp;

1. Object should spawn with different rotation than in 3den editor.

As you can see from the video, the first object "rook" does not have the correct rotation however the object with just yaw works perfectly. I suspect there's an issue with roll or pitch values.

I believe this function was made by @BIS_fnc_KK
