Here are two of the objects/scene I work on
For the Nuclear Fission Reactor (an assembled self-contained one):
For the Mining Site:
They are the easier ones.
For the Pressurized Tanks Array I must do some work , like merging some objects from different sources.
For the Humidity Trap, I must Remake entirely the object, the one provided in the FBX is completely screwed up:
For the Multipurpose Depot, I though I found one, but it is more a full fledged warehouse than a modest assembled infrastructure.
In this way I need to modify the data of this infrastructure, and it isn't the new one to adjust with more coherent informations.
For the Houses Pack, I found something simple for houses in Free Environment (directly liveable like on Earth):
For Restricted and Space Environments (with some mods necessary):
Of course it will expand over the time, and even affine but for now it's very satisfying.
