Ship is sealed but not pressurized?

[Little Sun]

My second ship is sealed but the vent says that the cockpit part is "not pressurized". The airlock has no windows and works perfectly. On the contrary the cockpit was fully enclosed with windows and it seems to be leaking somehow.

Tell please if there is any method / mod to know which parts are losing air ? I am on a Earthlike planet, the airtightness is enabled.

windows are not airtight when there diagonal

[Little Sun]

Really? Then what they are for?

[cptsavarus]

Windows ARE air-tight but there are Oxygen "voids" in some of the diagonal window blocks which can cause strange effects when the windows are arranged in certain configurations. One of the effects is that rooms may not pressurise.

The worst culprits are the 2x1x1 slope windows - an effect I've noticed with those is that if your astronaught is inside the block occupied by the window with his helmet off, he'll suffocate, even though the rest of the room is full of Oxygen & the vent reads pressurised.

Just built a ship with a 3x3x3 glass cockpit made of 1x1x1 sloped, flat & corner windows and it pressurises fine.

A fix will come but for now it's just a case of avoiding building huge windows, especially out of the larger window blocks.

yeah, that's been a thing forever. Make sure seats are placed well away from windows because one set right next to a window will cut off oxygen to the player once they sit down w/o a helmet on. Its a collision/bounding box issue i believe.

Here is how I go about making sure a build is air tight just as a general fyi.

1: Build w/e (obviously), and make sure you can either block off smaller areas easily with a quick wall of blocks, and then tear down that wall later, or have doors between each area.

2: have vents+oxygen tanks and generators in each area; at least one of each depending on the size of the room. Larger rooms fill up more quickly with multiple vents. This is two fold, 1 so you know for a fact that particular area can actually recieve oxygen, and 2 you will have backups in case of damage later on. Always have redundencies on everything. Thats just good advice all around. Why have just one of something when you can have twenty?

3: Seal off the first area with the door, or the wall, then check to see if the light on the vent turns green. It doesn't have to go full bars, just make sure the light is green. If it is, the room is sealed. If not search for where the hole is. This can be tedious and more than a little annoyng. Especially, when it's some weird place you never think to look that's behind something else.

4: Keep moving on, making sure that each area is sealed off from the rest until each is air tight.

5: Open all doors to make sure you didn't miss anything. If you did, start again from the opposite end of the build than you started the first time and go over everything again. Keep doing this until the entire build is airtight with all inside doors open.


6: Done


If a vent goes green, but all four bars do not light up you do not have enough oxygen in the system, or a vent cannot access it either through missing conveyors or other poorly placed conveyorable blocks: like an assembler placed backwards for example. Keep in mind that often blocks like conveyors tubes are NOT airtight and check around everything to make sure you don't have some silly block missing behind a refinery or something that hides it from view. Spectator helps with this, but not always.

To make sure conveyors are never a problem for you make sure when the run goes through a wall/floor/ceiling, place the six-sided conveyor block there to fill the hole instead of just running a tube through. If you do the latter, you need to make damn sure the entire run is airtight because it will leak otherwise. The tubes absolutely do not contain air. Can't stress that enough because many people still think they do, or don't even give it a thought one way or the other. If you must keep them out in the open for asthetics, cover them with windows and you can still see them, but they will be airtight. Remember that windows aren't very strong though and your build could depressurize easily if these covers are broken.

I have fully enclosed it with cubes, replaced every catwalk by a large cube. It.'s still "not pressurized"

Have an oxygen generator with ice, two tanks (4 green dots) and an external vent in sink mode. Nope.

screenshots, or a blueprint so we can take a look?

[Little Sun]

It looks awful now and the conveyors are between the cubes. All i need is a stable leak location method if there is any. I see a sort of wind leaving my airlock (it works), but the rest has no air effects.

Even if the hidden conveyors were initially broken the new vents (attached close to generator ) seem to not work.

[Karmaterrorᵁᴷ]

The only way i know is to just wall off more and more of it untill it does preassurise then build a horizontal layer at a time and keep checking. Its time consuming but you usually find the problem. I dont usually have any issues with windows preassurising, some blocks arent airtight even though thel look like they should be aswel :)

How do i show a blueprint?

[cptsavarus]

I think the particle effect of air rushing out of places only applies to
-doors
-airtight hangar doors
-air vents
-blocks that are damaged or cut away with the grinder.

Tiny holes between blocks will just prevent the room from pressurising to begin with, so you wont spot leaks that way, as there wont be any air in the room to leak out.

Really we need some screenshots in order to solve this one.
Better yet, upload the build to the workshop and link us so we can have a proper look at it.

[Little Sun]

There are no windows anymore, only black cubes from outside. It keeps leaking.

I'll try uploading the original design a bit later. The menu looks not very intuitive to manage it.

It's only a leak if there was air there to begin with!
Sounds more & more like you have an issue either with the air vent or the conveyor system.
Fear not though, we will know how to fix it as soon as we see it.

To create a blueprint, target the ship with your crosshair and press CTRL+B
Check it's there in your blueprints list by pressing F10. It should appear under a name like "Large grid XXXX". A small thumbnail image of the ship will appear when you mouse over the entry, so you can be sure you've picked the right ship.

To publish the bluprint...
Load a world, then enter the Blueprints menu using F10
Select the blueprint you want to upload & click the "Details" button
A new window will pop up in the top left of the screen.
In this window, click "Publish to workshop".
Follow on-screen instructions.
Only check the "Exploration" tags box if the build does not use mods.
If it does use mods we'll need to know what they are. I'll explain how to create a mods list if & when we need one.
Visit your new workshop page, right click anywhere on the page & select "Copy page URL".
Return here, click "Paste" in the text window.

In the Steam Workship there's a mod by Digi, "Build Info - extra block information",
https://steamcommunity.com/sharedfiles/filedetails/?id=514062285

Included in this mod is the ability to find air leaks. Once installed in your world, go to the air vent and open the control panel in it. There's a box to be checked that says "find air leaks", check this box and follow the dots.

[Little Sun]

odysseymwm, i tried this mod. It always shows how the air leaks through a nearest solid block... even if it is a cube.

P.S. Unbelieveable but this mod has both reversed and ruined a piston and teleported its head into a "leaking" spot!
