I can count as terraforming one of my current projects, wich is building a replica of the R.M.S Titanic using the little tiles mod, with blocks that are 1/16 of a normal one.
Rather unluckily in comparison to the yamato I didnt had a hull plan at my disposal since they are not either free or cheap.
So I instead plan to have each deck plotted joining each profile with lines for then refining it, although the bottom of the ship (wich I am currently working on) is a bit different, its curvy and I did find some “not excellent” but enough profiles of the bottom deck compartments.
Thats the bottom deck having each square steel plate awaiting for being shaped.
The process of shaping them.
And the result!
The project is currently a W.I.P and will be for years with all the likeness.
