Hey again!
This is the Dungeondraft-integrated version of all the Interior modules.
It is the fastest way to build a ship, and much more convenient than using Photoshop.
To use Prefabs, unpack the zip archive into USERNAME\AppData\Roaming\Dungeondraft\prefabs.
There may be a few minor bugs in the new prefabs, I will fix and reupload the archive in a few days.
If you had used the old prefab set, don't forget to delete it first.
By doing this, you can paste the modules not as merged images, but as a set of assets, that you can then recolor, rearrange, change lighting etc.
I hope it will make your creative process much easier.
See you soon! :)
