Only option would be to swap the guns yourself and save the edited ships as new blueprint for your server. I quit playing SE years ago, so there will be no updates. :-/

any chance to get your ships without the battle cannons mod? We don't have that on the server I play on but would love to use some of your ships.

Very Thanks, will test this !

Oh and it's the same script for the Twinport, only with TWINPORT CONNECTOR in the block's names.

It's a very basic script I made with the "Visual Script Builder for SE" ( http://dco.pe/vsb/ ).
You can copy it from the Greyhold's programable block. All you need is a connector and a interior light with GREYHOLD CONNECTOR in their names.

NOTE: Since it is a very simple script, it only works with ONE Connector per ship. If you have more than one connector on your ship, you will have to change the script for every connector (since I don't know how to use prefixes and stuff in my code). That's, why I didn't upload the script to the workshop. It's too specific.

Hope this helps

Nice one !! maybe do you have an Link to the "simple script for the connector status light" ?
