Do you have the source for this still?

would it work on old save?

@Hex okay, this is unbalanced. As much as I would love to have this mod enabled and play on Rime and have the farther biomes be -170C or even lower (Absolute Zero is actually -273.2C, so having up to -300C temperature would be awesome in some places, like the specific cold biomes, howveer can't be everywhere as oxygen would turn to liquid otherwise), this is not going to work as a challenge.

The moment I enter, the moment the cold is killing the temperature and it is impossible to progress. In particular if I have the "Diseases Restored" mod running as well, which punishes you hard when duplicants are around too cold/hot temperatures.

Would you be able to add some form of insulation to this, like even abyssalite, vacuum, or anything to slow/halt the temperature going down this quick? I want to go into temperatures this cold, it would be awesome, but not bare handed.

is this supposed to be a planet? cause i cant find anything with the name Absolute zero

biggest benefit to extreme cold is zero threat of germs, so you can go digging everywhere (assuming you have a dupe that has hard digging otherwise good luck!)

Combine generating heat with insulation to slow down heat transfer. The trick is finding a water geyser for your initial water for research. Then use it to create a central heating system with insulation in your base to bring it up to normal temps.

So there is no mechanics in game to prevent cold?

Config file

Background temp system is just mean. Everything is almost instantly -170C again. How do I stop re-freezing of stuff?

No not really. Never take any additional dupes and you can survive for a lot of cycles by mining around to find food. You have a lot of time to find a water geyser and set up a central hot water tank. Dupes get hypothermia initially but then after don't care about the cold. I've had dupes with a body temp of like -70c be completely fine with no hypothermia.

no, but water sure does, among other things at that temp, and if the starting zone is -170c there is less heat to keep back the impending cold that is moving in, so again IT MATTERS :)

Oxygen doesn't turn to liquid at -170c.

DDRMANIA, if the starting zone is too cold all oxygen turns to liquid. so in short, YES it matters.

does it really matter if the starting zone is also cold? It's not like Dupes die from cold.

Mod is broken as on 15 September. Starting zone temp -170.
May be on same default maps it would work, but I didn't find one.

DDR Not sure about the geyser thing, but for starting water you're going to want to find a steam or hot water geyser asap, either by luck or via Tools Not Included map browser. Then you could try using the algae distillery and insulated pipes to supply p/water until you get massive heating systems going. It's a struggle to survive and I depended on cheezing food packages, and the most reliable critter you can ranch earlygame is the shovel vole cause of it's -200c living temp.

Also how do I get water for initial advanced research? The ice isn't really warming up.

What does the geyser option do exactly? If it's on then they will be at their normal temps?

Whenever I try to make a new world with this mod, whether on it's own or with other mods, only the Printing Pod POI (18x7) is warm at all, the rest of the starter biome is frozen solid. The only way I could play was being lucky with a modded geoactive seed that had a couple of steam geysers nearby and active, so I could get the water needed for heating research. I think the background temp system forces the water to freeze solid after the geysers idle however, and I don't have enough output to get my tepidizer running before it freezes.
Seed is Terra 2089112709 with Better World Generation Management (Geoactive, Metal Rich, Slime Mold, Subsurface Ocean, Frozen Core, Glaciers) and other mods installed.

Untested, but it should naturally be compatible with the new update. Nobody has said otherwise yet.

Does this work on the testing branch with the new biomes? I'm yearning for a rime start that's actually cold ;)

turns out your best friend in this mode without the background tile thing at least is the metal refinery, just make a radiator across your base and itll heat the whole thing up pretty quick. just gotta be careful you dont overdo it XD

ok, well guess ill try and survive the best i can then lol

You will need to make a new save, it's all done on world generation.

awesome, is it possible for me to change it mid save or will i have to start a new save to remove the background temp? already 300 cycles into one lol

It applies to any world you generate with it active.

i subscribed but it doesn't show up in the world list, do i need to do anything else? i'm on mac

oooo, I like, what a great idea! Thanks for this

Where do I find the mod options? Love the mod. The game is very diffrent now, in a good way

There's now an option to turn it off.

Be warned, the early game will be substantially harder with no background temps to keep the start biome warm.

I'm working on additional settings.

is it possible to remove the background temperature so that i can overtime heat up areas?

heat from compost piles is barely even considered when dealing with so much mass being sub-zero temps.

my first attempt through I had 5 coal generators up and running supporting 20+ Heaters (I did not try using any vacuum methods for insulation to test it out). Lets just say that I was barely able to keep the cold at bay even with double layered insulated walls around my main area.

Once I ran out of coal it was game over; crops failed, dupes starved, and GG.

10/10 will try again, but going to try a liquid tepidizer next time around and see if it ends up being more efficient.

also, compost piles make some heat too, but im gonna try this challenge out soon

No, being colder than -170C allows oxygen to condense, creating that vacuum in the first place.

wait vacuum insulation fails at absolute zero?

The lava biome is cooled, yes. The only source of heat outside of the starting area is the surface, due to asteroids.

Gasses do condense and solidify, which is why I changed the default to -170C (just above oxygen condensation). You get a lot longer before cold is an issue (almost too much time for my liking), but you also can't abuse free vacuum insulation from such low temps.

so it's like helicona but with the ability to actually get to the endgame? sounds interesting enough, though i feel like the map will end up condensing and solidifying most gases in non-temperate biomes. i suppose the need to warm things like hydrogen and oil in order to use them presents a unique challenge. is the lava biome cooled to 3K as well?

100K is too warm, one of the more severe concerns you have is that oxygen will condense, which will not happen at that temperature.

I'll set abyss to 50C or so, so it's easily identifiable.

I only ask for abyssalite changed, because it would have zero impact on the overall changes, but I want to be able to quickly identify insulated routes. If abysalite is warmer than the rest, I can easily see it with temp overlay.

not a big concern, as there are other methods for me to see it easily (turn overlay off is one :D or material overlay) so no big deal if you don't.

maybe instead of 3k set to 100K? I feel it would give a little more time, but still provide a challenge.

I basically rushed for the tepidizer on my test playthrough, you need that as well as insulated tiles to stand even a remote chance at surviving. I had to resort to printing dupes constantly due to starvation, though.

I'm actually considering making it so that the temperature difference isn't a sharp change, so that the cold takes a little longer to creep in, and it would look a little nicer to boot.

I could make abyss 20C naturally, but why? It has no conductivity (outside of strange bugs).

Side note - is it possible to exclude Abyssalite from being 3k?

yes and no.. if you get lucky and that bubble is mostly made of igneous, it is a better buffer/"insulator" since it has a higher heat capacity, but the difference is marginal.

the real issue here is that there is nothing in the game to easily counteract such cold easily from the start.. it is quite the challenge. I insulated my entire starting area but then I ran out of coal and was unable to get more quick enough, all crops froze, then everyone starved XDDD

Also, being so cold, slime-lung is a non-issue so there is nothing to stop you from rushing to nearby biomes for resources, I just realized that too late :P

Sandstone is more insulative than the materials that layer is made of.

The reason they start at 3K is because they are not actually inside what the game considers the starting biome. There's an odd discrepancy between biomes and borders, with borders not actually being strictly correct. It's most noticeable when you get elements that only spawn in one biome (i.e. ice) spawning in another (i.e. slime biome).

One issue I have thus far (only 6 cycles in) is that the "insulation" layer around the starting biome also starts at 3k. This means that immediately from cycle 1 the starting biome starts to freeze, rapidly.

Is there any way to change it so that the insulating layer around the starting biome starts at normal temps? Otherwise if I can't get heaters up within the next few cycles every dupe will freeze :(

It works regardless of world settings, and only needs to be enabled for the initial creation of a world.

interesting... does this work regardless of world settings or do you have to select a specific world start?

omg I always thinking this myself ,instead of hot game a cold game will be fun.
space heater etc will be useful lol.

need to change wheezze to cold to 3K too so everything keep going down
