Would be great if we had the option to blacklist/whitelist certain weapons from being added into the turrets.

There is a plugin by misticos that restricts what is placed into turrets, but that will affect all turrets, not just these modular car turrets.

Thank you!

I figured it was only a matter of time before somebody asked for something like this. I will add it to my long TODO list.

One wrinkle I'll have to figure out is the interaction with Turret Loadouts. Currently it will try to auto fill items. I'll have to ensure it doesn't override the rules, and to avoid printing errors if some of the loadout items are blocked.

I have no doubt you can achieve it.  You rock!
