Quite the shame, wonderful trench design however. Great job, Devil_Creator.

No, it's one pack that you spawn, but you then delete the sets that you don't require.

Is there any way I can just spawn a certain trench part in the editor instead of the entire composition? I'm not experienced with Arma 3, so forgive me.

I use this composition all the time, it's awesome. Is there any chance you could optimize the simple objects in this composition? I do this myself manually every time but I would appreciate it if you could implement it into the composition.

For most objects under layer "Simple Objects," I always change the init fields from:

this call bis_fnc_replaceWithSimpleObject;

to

if (isServer) then {
this call bis_fnc_replaceWithSimpleObject;
};

I do this for multiplayer optimization, otherwise every connecting player's machine attempts to replace an object with a simple object.. Could you update this composition to include an ifServer check?
