spacebuild mapping help

I have been working on a spacebuild map, and I got it to work, but I want to know if it is possible to change the levels of oxygen, carbon dioxide, hydrogen, and nitrogen, instead of just saying breathable air/not breathable air.

I don’t think so.

Yes it is.
(Assuming you’re using SB3)
Using cases 09 through 12.

I am using sb3. So now that I know its possible, a little explanation/tutorial would be greatly appreciated.

Intresting, i would like to know aswel

This?

Aha! Found it.
