Holding oxygen in a station (Problem).

[Vairon]

Hi, i'm new here and i was wondering if certain blocks can't hold oxygen?, the thing is that i was making some adjustments to my station and it looks like this:

The corridor is made with half slopes, windows and ramps, there is no gap, BUT, somehow the oxygen never stays in the station.

Can somebody help me with this?

I am pretty sure your problem lies with the half block slopes. Iirc, they are not considered air tight at all. The blocks in question would be the ones around your windows on the walkway. The ones on the lower side by the door, only the upper ones would need to be changed.

The other thing would be that the sides of those slope blocks are also not considered air tight.

It might be helpful to get the build info mod as it can inform you as to what blocks are airtight and what sides of said blocks are airtight.

I use half blocks & half slopes with windows in a *lot* of my builds & have never had any problems with them being airtight.

Honestly can't see anything here that should present a problem with this design.
The only type of block here I can't vouch for is the 2x1 ramp.
If I recall, those used to have gaps in the corners. Not sure if that's still the case but I suggest testing it by replacing them with 2x1 armour ramps.

It is either the half-slope, the 2x1 ramp, or a combination of both:

2 2x1 armor ramps set up in a similar fashion to Vairon's stairwell showing interior air tight:

Changing exterior block to half slope and interior is no longer pressurized:

Use of a full block (in this case the tip of a 2x1 armor slope) creates an air tight room:

Great testing there!
In this example you give though, what happens if you turn the half armour slope upside down, so its other merging face is against the edge of the window, as Vairon has it in his design?

Strange that the window "leaks" when the half-ramp is in the orientation you show.
Almost all my designs use it the other way up.

You sir were right! only the ones in the window needed to be replaced with the larger half blocks! here's the result of how it looks now:

The issue is not the window, but the half-slope's interaction with the 2x1 slope's side. The side's of the 2x1 slopes (both armor and ramps) are not air tight, and the same is for the half-slope I believe. The reason why it is not it's interaction with the window is due to the fact that the window is itself air-tight on the face that matters -- the one towards the interior.

Ah, I see!
That's interesting.
I can see how 2x1 ramps would not be airtight on the sides, as they have that "structral" looking framework stuff going on & gaps all over the place.
I almost never found a use for those ramps personally but good to know, so thanks for the testing & info.

Kind of surprised to hear the same is true of armour slopes though. I was under the impression all the armour shapes had been fixed for airtightness.

Might be worth someone posting on the feedback site in case Keen aren't aware.

[Bahamut]

I believe the issue is in Keen's airtightness coding. I believe they have it simplified to true/false state for airtightness on each grid face of a block. This means that regardless of whether the combination doesn't have any gaps, if neither of the mating faces are set to airtight, the combination is considered to not be airtight.

[cptsavarus]

You seem to have done your homework on this!
Are these true / false flags a transparent "layer" of the 3D model do you suppose - like merge faces or are they separate definitions found in an xml file somewhere?
I'm thinking if it's a definition it'd be easy to fix with a quick mod.
Haven't done any block modding before, so unsure which file it'd be in... if that's how it works I mean.

[Bahamut]

I have not messed around with any block files or anything like that. Just what I remember from the couple of times I used the build info mod and what I have seen in game when it comes to the various blocks.

[cptsavarus]

Well it's a start.
I'll see if I can work it out. If it can be fixed with an xml mod then maybe some other blocks can be too.
If it turns out to be part of the 3D model then it'll be for someone else to do, as I know less than nothing about that side of things.
