Sorry, I didn't know that that is what tourists means.

Ok, I will try to give an example: You open an habitat UI (f.e.). There, along with the other bars, stands "Hygiene" or "Cleanity", even if that is not a real word. It says 100%. As soon as you run out of a certain ressource, f.e. Disinfectation Liquid, that "Hygiene" bar will drop. And when it drops below 40%, your Kerbal has a chance of getting a disease. Now the Kerbals UI also has a bar which says "Health". Once that will drop below 50%, your Kerbal will "die", but without the death part. Which means that he wont be able to control the ship, do EVA's and so on, but if you give him medicine, his health bar will fill up again. Although when you dont give him medicine, and the bar reaches 0%, he will actually die. There is also a change that when there are other Kerbals with a sick Kerbal in a habitat, they will get the disease too. It could even transfer between habitats. As long as a Kerbal is sick, he carries the disease with him, meaning that moving between habitats wouldn't be a good idea, since that could infect other Kerbals. The best thing would be to have a medbay, but since you're a coder and not modeller, that would require some help. I hope that you get it now, because I lost track halfway through

Well, every shortage of a resource just causes death. But getting a disease could become a serious problem, if you are having something like a super colony. One kerbal could get infected, who would infect another kerbal and so on. If the disease goes around long enough, your entire colony could just die out. But, as already said, I think this would only be "useful" if you have a really big colony with alot of kerbals.

Maybe some kind of hygiene. That when f.e. the hygiene of a ship drops below x%, your kerbals start being less productive or get diseases.

Is there a way to make this work with the Kerbal Planetary Base Systems Science Lab and ISRU?

This comes just in time for my Duna mission. Good work

Is it possible to put cargo bays upside down (cargo bays open downwards), but still keep the black texture at the bottom?

Where are the big cube parts?
