I figured out the problem and I managed to made my own custom size for the ship, but I'm waiting for you to make more Legend of the Galactic Heroes ships, they're all really well made and I love the asethetic of Imperial Ships

This ship uses a custom turret. A turret design must be registered on the turret base.
Note the size of the turret base. The turret base must be of regular size.
The turret base of this ship's main gun is 1.5 x 1.5.
Did you change the size of the ship?
If you change the size of the ship, please try the turret base 3x3.(200%)

Hey I know you can't speak English very well but can you please help me with something? I've been using this ship and I can't get it to work properly, I place down the turrets but they won't fit onto the ship, and they won't be considered real turrets either, how did you get them to fire like in your video? I'm posting this comment on the video itself too.

Thank you! I think I fell in love... Now finally the Galaxy can be freed from the Rebellion of the "Free Planets Alliance" and be brought the peace of the Goldenbaum dynasty. ;)
