Hi there,    It's true that: - Massive Constructs "battlestar cruiser" size or "death star" will require incredible amount of resources and may not (or hardly) be possible to build alone. - We don't plan to let players import design from 3D tools like 3DS Max, Blender or Zbrush.   However: - It's also true that trial & errors will have a massive cost in resources if designing/prototyping a very large of spaceship must be done in the "real" in-game universe.
