I have to elaborate on this further. lets take a look at B_G_Offroad_01_armed_F

It has the following init statement to call randomise script:

init = "(_this select 0) execVM ""\A3\Soft_F_Gamma\Offroad_01\scripts\randomize_IG.sqf""";

randomize_IG:

if (isServer) then {
_this execVM "\A3\soft_f_gamma\Offroad_01\scripts\randomize_doors.sqf";

_this animate [["HideBumper1","HideBumper2"] select floor random 2, 0];
_this animate ["HideBackpacks", 0];
_this animate ["HideConstruction", 0];
_this animate ["HidePolice", 1];
_this animate ["HideServices", 1];

_this setObjectTextureGlobal [0, "\A3\soft_f_gamma\Offroad_01\Data\Offroad_01_ext_IG01_CO.paa"];
_this setObjectTextureGlobal [1, "\A3\soft_f_gamma\Offroad_01\Data\Offroad_01_ext_IG01_CO.paa"];
};

randomize_doors.sqf

if (isServer) then {
_rnd2 = floor random 2;
if (_rnd2 == 1) then
{

		_rnd3 = floor random 3;
		_this animate [["HideDoor1","HideDoor2","HideDoor3"] select _rnd3, 1];
		if (_rnd3 == 1) then {_this animate ["HideGlass2", 1]};
		_this execVM "\A3\soft_F\Offroad_01\scripts\randomize_doors.sqf";

};
};

While I understand the need to hide various elements of offroad to give it military look in randomize_IG, calling randomize_doors IMO is unnecessary and badly implemented at that. Let me explain.

The use of execVM leads to unpleasant visual effect. Offroad spawns with all doors and then user can see the doors disappear in front of his eyes. Why? Because execVM works on its own time, it is up to the engine when to run execVM code, milliseconds or even seconds after command has been executed. Apart from unpleasant visual side effect there is this other thing.

If you want all doors back, there is no way of telling if execVM has finished and you can safely add doors back. You can wait for a second and add them, but if execVM took 1.0000001 seconds to execute the doors may get removed again after you added them.

Another issue is with design of the script. As you can see randomize_doors calls itself!!! This means that theoretically it can go on for a long time, hence making even more impossible to predict when execVM is done. I've had all 3 doors removal happened, this means that randomize_doors was called at least 3 times or more.

Thirdly, this randomisation is purely artistic decision, therefore this should not be hardcoded and imposed on the user. Please give us an option to disable randomisation at will, it is very simple to implement.

Thanks

These issues really are a mission makers worst nightmare.
It's nearly impossible to customize the looks of civilians because of this.
