Well, at least the Polarstorm ship set is not so ugly as the Bezimeni ship set, right? oh, and you can tell me how I can add the Amarr ship set - and only the Amarr ship set - in my PC?
Actually I would advise against it. It's most likely not configured the same way as the shipsets provided with the mod (so it will select the models based on size alone, not on hull type used) and, more importantly, adding another shipset will increase the mod's memory usage even further. The mod can cause frequent crashes as it is, so I would rather advise removing
shipsets instead of adding new ones.
If you really
insist on trying it for yourself, though, the installation should be pretty simple. I assume the shipset comes packed in an archive (.zip, .rar or .7z). Somewhere in that archive should be three folders: Game Data, Images, Models.This is important, read it carefully:
If you want to add the shipset to the Galactic Armory Mod instead of the base game, extract those three folders to the mod's main folder, which should be Star Ruler\Mods\GalacticArmory
or Star Ruler\Mods\galactic-armory-1.9.4
Basically, it's the same procedure as with the Mirage Battleship Gray shipset; I'm sure you'll figure it out.
