Oh i see you mean ghost part in ship, well yeah but we need to be able go in and out of ships, and im not the creator of the walls mod so i dont know how its made.

maybe i'll try a day to make an addon for wall mod with "missing" solid part of ships, but it will be solid so you'll have to remove them each time you go in/out, or use a teleportation tech.

I'll try to explain it better, ah... The parts where you've cut off pieces of the ship's structure to allow access - in particular, the T5 and T6 ships' cockpits - can't really be built 'shut' using anything in the Better Ships - Walls mod. The blockades end up looking kinda slapdash. Having solid blocks that mimic the removed structure geometry would be nice.

That mod use the Better ship wall mod too , its not ok for what you asking ?

or maybe i didnt understood what you ask

There's one other thing I'd like to bring up - there doesn't seem to be much in the way of building reasonable-looking pieces where the ships are accessed. Since I'm using WTM to warp between the ships, I've had to use stopgap solutions to block off the cockpits of the T5 and T6 additions. Adding some placeable fragments in the shape of the parts removed from the ship pieces would be nice.

Can you make one for the Hylotl race?
