Hi, a lot already shared the Space Battleship Yamato as Blueprint, some go up to 50K blocks with Mods and some are smaller.

You should try some, paste in Vaniila no Mods world, in space (no Gravity), paste without the Mods used so you can complete to your liking, or at least to see how much blocks it needs and if you like the size.

Type in "Space Battleship Yamato" in the Workshop search tool, you will see there are a lot.

Done checked all of them, most tgat are in tge 10k block range use modded blocks and do not specify the block mod

You don't need the Mod at all, I would paste in without the Mods just to see how much blocks it need, because 9K blocks seems low for that ship, in my opinion = 20K would be a minimum.

Yes, I have tried to past them in and no hull appears.
Hence why I am trying to commission one specifically to what I need. Kinda hard to design something when I am working 12 to 16hr days

Ok, there are so much I thought one would fit your needs, looks like you will have to wait for a kind player wating to do it for you.

I wish lol been hunting for months and trying all of them on the workshop. Even took one that was meant for tge water mod and retrofitted it. It worked for awhile but I fail to have the skill needed for such a specific design
