DecaByte Oh, okay, thanks.

Maoman
This is now part of RiverFish mod. Properly formated & fixed. Feelfree to download it there.

DecaByte could you post that on Pastebin or something instead so the formatting is retained? I was able to edit it to work again but most people won't. 

Cracking up at "Vanilla Vintage Story" being a "highly recommended mod" 

Is this compatible with Terra Prety? Thinking of using both for a server but i'm not sure if they will conflict. Thanks :p

Sylvaris yes

Is Better Ruins compatible?

you updated wildgrass, either use the 2.0 version of biomes or use an older version of wildgrass

Wildgrass suddenly stopped playing nice with Biomes. Didnt update any mods or change any configs. Been playing this world for a couple weeks no issues, but today it just doesnt want to work anymore.

1.2.2026 13:43:07 [Error] [wildgrass] An exception was thrown when trying to start the mod:

Oh that's cool, vs mod db decided to just stop giving me notifs. Sorry for not responding to any comments here, I was checking the notifications and not seeing anything and assuming there weren't any.

Been super busy and haven't had a lot of time to work on vintage story stuff. I have a few unresolved things I want to do before rolling over to a release candidate, but the current version should be mostly stable. 

getting a similar error to Amarillo once every second in my server console regarding inability to spawn mobs. i only have equus and pegasus installed as custom mobs

Is there any way to control what biomes spawn next to each other

DecaByte thanks for your patch! I incluided already to my mod River Fish

I am having some errors in console of the mod not able to spawn entities. Im not sure why

I got fish at spawn in starting biomes, thanks to the new River Fish mod! I did have to add a riverfish.json file to the Biomes mod folder.
You just have to create a riverfish.json file for the 'VintagestoryData\Cache\unpack\biomes_1.21.0.zip\assets\biomes\patches' folder.  
Here's what I put into mine after I researched the biomes for these fish. You're welcome to use it. Json formating is borked cause of chat formating. Just fix it as needed. You can use another file in the patches folder as a referance for formating.

@decabyte (I don't think tags work on mobile, I'll edit it when I'm on my PC if you don't see it.)

The command is what I meant, I said debug as short for "debug command" and didn't think about the debug log.

Your assumption is only 1/5th correct: I did check on a default sized world....and then on one with different settings for landform and such. One without rives at gen. A very tiny one, like probably bare minimum to have any meaningful chunks for spawning and I traversed many, many different biomes and checked for all sorts of fish+ listed as compatible with the mod (and confirmed to be within the files) and in all that testing I maybe saw a handful with the previously noted sunfish and other being the most significant find because they were in relative proximity. Iirc that was the smallest world I generated too. 

It's awesome that you're getting spawns, I'm jealous, maybe it's some incompatibility I'm not seeing, though I did do a test run with just biomes and just the mods that add water life and the results were the same (I was sure at one point for some reason that primitive survival was to blame, but nope. Idk where I got that idea)

I didn't see any mention of biomes compatibility being built into that new fish mod, so whitelist would be the way to go. Looks cool, and was an instant install.

MiraLeaps

What do you mean by "seen by the debug"? As far as I could tell is you can only seen what Biomes Biome you are in is by command /biomes show. How do you see it in debug? Also I assume you are using defalt world size. I had to tp 400000 # 0 & -200000 # 0, just to get to the next Biomes biome which was the Pacific palearctic & Alantic nearctic. When I got there fish were spawning in like normal. Players start in the alantic & central paleacrtic just to referance as far as I can tell the vanilla & mod fish dont spawn in these Biomes cause they wouldn't be in those biomes in rl.   
There is a new River Fish mod that adds, I believe, fish that would be in those biomes in rl. Now Biomes need to add those new River Fish to the biomes. You could add them to the config whitelist, but I'm not sure the config is working as I tried adding fish in the older builds, before the recent updates, & it didn't seem to work.

New mod River Fish  may help with the fish issue as it adds the type of fish that would spawn in the world spawn biome. Not sure if we need to whitelist them in Biomes config or Biomes needs to make changes to mod. I hope it works out of box.

DecaByte there is an assumption there about something that I got a mention: I not only tried spwaning (and traveling) to other biomes (seen by the debug), but I also added my own alterations to 'open up' where fish and other water-life were meant to spawn (a lot of these by default are really open as far as I can tell) and still, barren rivers, lakes, and oceans. When I finally got fish to spawn (one sunfish stuck in a river far to thin for it, and one other ghostfish from FSW) it was just the two for many many chunks.

I went back to older and alternate versions, I whitelisted, changed and added stuff in the core-files. Short of cracking open the dll and doing stuff there, I've tried everything I can and the disparity between fish in the vanilla handling and fish with biomes was rough.
I put hours into just seeing what magical combination of mods and stuff would get it to work, and everything failed me.

Just to be clear to folks as a little counter there. No hostility intended or anything, we're all on the same team rooting for the mod.

actioninja

A while back, before the recent updates, I looked at the fish not spawning in lakes issue. From limited testing & understanding of JSON file system. This is what I think is happening.

First, people are spawning at default world spawn & the biome, central palearctic, there dosent have fish, as vanilla salmon are not listed spawn in that biome, they should spawn in other biomes. Players not seeing fish & are saying there is no fish cause they still in the same biome.

Second, Looked at the files & vanilla bass is listed to spawn in the central palearctic biome. But when I look at the vanilla bass code, it looks like its not complete therefore not working. Third, Mods I looked at to add fish to VS. The mods don't add fish that would be in this the central palearctic biome normaly. So Biomes doesnt add them.

I looked into the types of fish that would be in the central palearctic biome in rl & the only fish would be some types of bass. Other fish that are native to that biome are not added by any mods I can tell.

I tried added the fish to the whitelist, but at that time I read it wasn't working & didn't really test it throughly.

In looking into the fish of the central palearctic biome region in rl & found that biome does have a few types of fish that are native. But no mods add that those types of fish. You could add fish that dont belong there, like a catfish, & pretend it's a non-native invasive species.

I dont know if any of this is accurate anymore. I hope it leads you in the right direction on the issue.
Good luck! We're all rooting for you!

If you get that working, I'd reinstall in half a heart beat. I love how it handles stuff otherwise 

Asil The world isn't neccessarily divided into continents it's more like big rectangles. They have a certain degree of "overlap" where you'll get spawns from multiple regions.
You can change the order and placement of these by changing the user config, whatever is in the "center" of the northern realms is typically what you'll end up spawning in.

With the default config, you typically spawn in a combo of atlantic palearctic and central palearctic but you can check with /biomes show

MiraLeaps I'll look into it, the way entity handling has been handled in the mod has been quite suspect to me since I started refactoring. I duplicated the original mod's implementation but I have a strong suspicion that implementation is flawed. I've also noticed a lack of fish in testing, and verified that even pre refactor there seems to be a lack of fish.

I'm not sure if this has been asked, but can you tell which region you spawn in and can you choose a continent?

Hey, to add to the report of fish being somewhat broken with this mod......fish are somewhat broken with this mod.

Tested it with some mods and go 0 fish flying around, pausing to wait, letting it run. Barren waters.

Tested it with only mods that add fish....maybe one or two fish, every once in a while. Make a 10k block world and went to each corner...legit only saw like two fish. Checked and those mods weren't throwing errors and spawn fine without biomes on. 

Biomes is a cool idea, but with the fish gone it really is something I can't use.

Some sliders or a config allowing for the overall adjustment of spawns would be nice as well....it feels like things are cut way down in general unless maybe you add all the fotsa packs while using enough ram to make openAI jealous.....

Which I did add them all and tried and it was still a bit underwhelming what spawned...but again, the fish was the worst.

Wishing you the best and thanks for the work and effort

I'm not getting biomes. I have all of the Floral Zones mods installed and before installing biomes i could see a lot of plant variety (even if plants form different parts of the world were mixed) but since I've installed the biomes mod I only get vanilla plants plus the ones from the Cosmopolitan floral zone. The only biome that seems to scarcely pop up is the mediterranean one, and only some plants like olm oak and milk thistle. I also use the FoTSA mod series, Terra Pretty and Rivers (along with a bunch more, but never had any issues before)

I'm not sure if this has been answered, but can anyone recommend some fish mods? The rivers, lakes, and ponds all around me are barren and lack any native wildlife in them. It's pretty depressing and kills immersion.

Alright, I understand what the issue is. They have an incorrect biome definition as "oceania" instead of "oceanic." Failing that catastrophically and unclearly is bad though, I'll make a release which makes it more predictable.

Hi, just wanted you to know that there is some kind of conflict between this mode and "Rivers" mod that prevents any kind of vegetation from spawning on world creation. Investigating further...

Edit: i have investigated further and i haven't learn much except for fact its not  Rivers mod. Game at generation throws this error:

10.12.2025 21:33:31 [Worldgen] An error was thrown in pass Vegetation when generating chunk column X=15998,Z=16000 in world 'Gloomy Kingdom Tales' with seed 390112929

However, I wasn't able to pinpoint mod that causes this. it seem to be an isue of biome "oceania".

Edit 2: Found it! Soap and Lye: Bloom and Lather was the culprid. After disabling it everything runs fine.

actioninja thanks ☺️

Katzvielle been fixed but not in released version

Sidfu issue is that Wildgrass is directly using a bunch of internal interfaces I didn't expect people to actually use so I've been changing completely willy-nilly. Made me realize there isn't actually any kind of stable API and I'm now working on one.

gave the newest a quick try on a test world.
wild grass comp seems to be broken. also reporting it on wildgrass mod

i got almost the same warning as last time i dont know if i should let you know or not but here you go

[Warning] Entity "primitivesurvival:willowisp-yellow" has no cache data, likely has no compat data for Biomes.

[Warning] Entity "primitivesurvival:livingdead-normal" has no cache data, likely has no compat data for Biomes.

Is there a way to get myself to spawn in the Atlantic Nearctic? 

Siegfried_Brehl pink salmon aren't native to Europe and thus don't spawn in the starting regions. If you want salmon you have to travel out of the European region, the only fish you can find there are saltwater fish.

got this warning

[Warning] Entity "primitivesurvival:willowisp-green" has no cache data, likely has no compat data for Biomes. Report this to biomes!

I'm not getting any fish spawns, im not really sure how to fix, any fixes?

Dumb question, is this fine to just update for small patches like 

"

• Internal split of config into a seperate class from the main mod system
• Several minor fixes to compat and whitelisting contributed by ShaeTsu"

ShaeTsu This should be resolved now, sorry about wrecking your changes as well. Been trying to use jujutsu vcs over git recently and still getting to grips with workflows, and I've done this twice now.

Once I finish with getting biomes in a state I like, I plan to write a testing library for vintage story that should hopefully make issues like "filtered spawning is completely busted" easier to identify before actually pushing new versions. Since stuff like this is basically entirely RNG, I happened to have tested worlds where I loaded in, flew around for a minute, only saw valid spawns for the biome I spawned in, then assumed it was working correctly.

actioninja Just to be clear, my further testing shows that it isn't working at all for entities on worldgen. I've seen raccoons in atlantic/central palearctic for example.

Also you recently reintroduced broken critter pack compat that I fixed in a PR a while back. I made another to fix it again.

ShaeTsu Sorry for not addressing this sooner, I've been busy from a combo of the holidays and actually playing the game. Entity caching hasn't really been tested properly since FOSTA is so heavy that I generally test without it. I made a small behavioral change for dev purposes that entities that aren't supported are allowed by default instead of not allowed by default, and this is likely related. I'll try to get a release out to correct the issue, then add a config option as to what the default "no support detected" behavior should be. I'm close to finishing the refactor, then I'll go to release candidate for a bit to make sure issues like this don't remain.

Scratch that. It's entity spawning on worldgen in general. No entities are respecting the local bioregion.

Nice to see that this mod isn't going unchungused

Im happy to see this mod getting help with more updates! I hope that compatability with the FotSA mods will be fixed as this was the main reason I used this mod ^^

Latest version is not correctly restricting spawns on worldgen from mods that handle compatibility on their side. I'm seeing north island giant moa and south island geese from FotSA in atlantic palearctic. Both of these should be restricted to oceanic.

Distorti0N Sorry, version I told you to use was completely busted and didn't actually have any code in it due to a build system error :/
Latest should be pretty stable now, but shame to hear of spawning issues on the original version. Was hoping it would be a more stable alternative.

actioninja I was using the last stable, non-dev, release; 1.21 as I wasn't keen on introducing unexpected behaviour with dev releases. 

That being said, I see a handful of changes have been made in subsequent updates so I'll backup my world and give the latest dev release a go to see if anything improves anyway. 

Edit:
On loadup, I am presented with this error. The save continues to load as normal after the fact, but I am unsure how this impacts gameplay. 

26.11.2025 20:25:23 [Error] [biomes] An exception was thrown when trying to load assembly:

Distorti0N Are you using the dev version or the main version?

EDIT: If you were, download the latest version. There was an issue that was resulting in no biomes being considered valid for spawns if season wasn't specified rather than all biomes.

Is anyone experiencing or can point me in the right direction of troubleshooting the reduced animal spawns? 

What should I be checking, logs wise, commands, configs? (I have added anything found in unconfigured to the whitelist, except some of the egg and tamed entities from FOTSA and such)

My partner is pretty damn sad that all the various animal mods we have downloaded have nothing to show. 
We just got back from a months-long travel by land and sea, almost a hundred thousand blocks away from spawn, and across in many directions... And the only unique animal we saw was a Rhino. (So something must be working right?)

Other than this, none of the various capreolinae from FOTSA, which should actually be spawning near our home region, according to the command "/biomes entity" or any of the other FOTSA mods appear to be loading. (Even though they show in the entity list)

She is a big fan of the sea, so had expected to see, in the literal hours of time spent by sea, SOMETHING swimming along, but not a single fish was. Not from vanilla and not from the 4 or 5 different fish life mods we have added. 

With the exception of ornamental fish, since this was added to the whitelist. They seem to be loading in small water areas. 

At this rate we would have been happy to see even some salmon on our large water travels, but nothing. 

I really love what this mod is trying to do in adding value to travel, because thats what we love, but if I knew it meant trading the joy of animal discovery in for this level of tedium in simply trying to find animals then I would have chosen otherwise. 
(Not to say we werent thoroughly entertained by all the landscapes, better ruins and loot for the loot goblin along the way)

It could be that we are tremendously unlucky or that there is something set incorrectly and after proof reading, my comments seem a little dramatic, but man, my girlfriend wanted to see some turtles and dolphins while we travelled yaknow. 

Thankyou so much for working on this. i cant wait for the update. 

👋 I'm currently in the middle of a pretty major refactor. I would push the previous optimized versions to this page, but the crash reports I haven't properly investigated yet and it would feel irresponsible to break the game for some people when I haven't even figured out what's broken.

I've added two new team members - actioninja and hydromancerx. Hopefully they can help get some of these issues resolved and keep the mod maintained.

SpacedInvader after playing around i did find fish using this version https://mods.vintagestory.at/show/mod/35666 i just had to go in creative and check deep pools of water for a long time, they were very hard to find. fish do not spawn in rivers if you have that mod on. anyway i just wanted to let you know.

@Katzvielle i had no fish in my world long before i installed primitive survival.

SpacedInvader im not 100% sure think having no fish in the world has something to do with Primitive Survival

How do i add fish back to my world? My lakes and oceans are devoid of all life. Im running on gportal if that makes a difference...

i'm also pretty confused becuase you list the fauna of the stone age series as being compatible yet when i ran the command to show unconfigured entities the results were 90% all fauna of the stone age related animals. I had to go in and whitelist a bunch of it which I'm not even sure if it worked.... I added "salmon" to the whitelisted entities too but still haven't seen any so far....

I love the mod but not if it's going to break animal spawns for my game...i might give this a skip on my next game although it sounded good in theory.

There is an optimized for performance version of this mod as a fork by Actioninja https://mods.vintagestory.at/show/mod/35666

Aksyl

please do, i had no issues whatsoever on 1.21.4, bearing in mind im playing with a big modlist

Rikaiu I'm testing this today, I'm using the new "Simple VS Manager" and I see several "no issues noticed" votes on it, and since I have nothing better to do today, I'll update here.

You may be encountering some incompatibility otherwise.

doesn't seem to work for me on 1.21.5, commands don't work for me (says they don't exist) and i keep finding elephants in temperate climates

Nephelangelo If you change your block codes from stuff like flower-whitecatmint-free to flower-catmint-white-free it'll work out of the box.

If you want to keep the same block codes, or if you want to restrict certain flower colors to different regions than what the mod is doing for the vanilla varieties, you'll need to patch biomes2.json. I was planning on doing this myself soon anyway, because I use both mods. But I've had a PR sitting on the repo for like 5 weeks to add and fix a bunch of mod compat, so the author seems MIA. I can send you the patch when I get around to it if you want.

Ahoy there, I'm looking to make the new flowers from my mod Material Needs compatible with Biomes. They are all real world color varieties of existing vanilla flowers, patched in to operate from the vanilla resources. What would be the best way to make them play nicely with Biomes?

The east west biome relationship doesn't scale the same way on a 1.25 mil square as it does N/S with default equator settings (100K)

This is a "read the fine print" kind of suggestion for those using this mod. Please learn from my user error. If used as intended with otherwise vanilla settings, you get a really, really big world. And if you are using other mods, such as Alchemy, that rely on specific flowers, your players could end up losing their minds because to find a golden poppy for mining potions they have to travel like 350K blocks just to get in a zone that "might" spawn them in the Pacific Neararctic.


I am guessing that if I remove Biomes from a world generated with it that I will get massive chunk border issues, among other things?

I am guessing that I would have needed to set the actual world size to be 200K x 200K with the pole to equator distance left at 100K to get a map where the distances E/W make more sense relative to the pole/equator distance

Crabb PR updated for the new wildcraft fruits version

Thallassa You need to edit vanilla-water.json in /patches

How can I edit this mod so salmon are whitelisted/will spawn everywhere? I tried adding "salmon" to the whitelist in the configuration file, but doesn't seem to work. I also tried editing biomes2.json but couldn't find salmon in the list. 

@ManManGuy10

Had the same question, ended up finding the answer from the author:

"Biomes and terrain-gen mods don't interfere with each other, so you're good to use Conquest Landform Overhaul and Biomes togehter"

Yelb I believe a solution to this is using the "Hot (28-32)" starting climate selection in the first settings option for your world creation customization menu since this will cause 0, 0 to spawn roughly at the equator from what I can tell. Hope this helps!

Does this mod work with terrain changing mods such as "Plains and Valleys" or "Conquest Landform"? I know it might be a stupid question but im not sure if this mod just changes the biome placement, or the actual terrain in any way.

Crabb heads up I've made another PR that fixes some issues with critter pack compatibility.

Heya Crabb have you gotten a chance to check the incompatability with some of the FOTSA mods?

techy if you read any of the floral zones mods you'll see that they're compatible.

Any integreations with Floral Zones mods like https://mods.vintagestory.at/floralzonesneozeylandicregion ?

Hello,

How can i spawn (0, 0, 0)  at equator, and have north/south pole equidistant, like 250K each for a 500k size world ?

From other discussions, I undestood the game generates the midle of the world at player spawn, and it can never be at strict equator for some reason, and so the world is actually excentred.

South pole is out of the map, and north pole is not the top, you can keep walking and it gets warmer.

For some reason I can't use any of the biomes chat commands and I think it broke the generation of Fotsa and floral zones:series mods. It's like it stopped working but in the logs the mod biomes is loaded so Idk. Update: the mod stopped working. 

Does this mod block unsupported mods creatures from spawning or just let's them spawn everywhere like normal?

Crabb my world is 1million by 1million, 400k Polar Equator, which is my standard size. I went all the way to about 350,000 north from spawn in a straightish line

"FruitTreeBiomes": {
"shea": {
"biorealm": [
"atlantic palearctic",
"eastern afrotropic",
"atlantic afrotropic"
],
"bioriver": "both"
}
}

Note that compatibility for this mod is handled on their side, not on Biomes side.

How big are your worlds? Rikaiu Raelin

Yes it's safe to remove mid-game EthelVril

Hi, I'm wondering what the spawning conditions for fruit trees are. We have Terra pretty and Biomes and so far I've seen 4 types of fruit trees spawn (Mostly cherries in the north and olive/breadfruit to the south. there are mabye 2 confirmed pears), and I've been searching for shea trees from lather and bloom without any luck. If I had to guess apple trees would be in the americas?

same here, i've gone 10000 blocks away into a jungle and it still says central paleartic for me. also the foxes from fotsa don't spawn, instead the vanilla ones do

Havng an odd issue. In my last world the biomes tracked just fine, but I've been teleporting further away from my start to explore and the game isn't recording anything but central paleartic. I've gone from 0 to -300000 and its still the same

The grid stretches horizontally to take up the width, but it can repeat vertically. I would tend to make a smaller world for use with this mod just so all the biomes are accessible in a reasonable time but of course it's personal preference.

Ok, cool! With that in mind, how are they distributed as far as size/distance goes? Do the various biomes average out across your world width setting or is there a set distance? I'm curious if I've made a mistake not limiting the width of my world.

Yes the biomes are laid out in a grid and the arrangement is roughly equal to the real world. So yes you will hit Eastern Palearctic if you go east from Central Palearctic, and if you went south instead you will hit Eastern Afrotropic. It's a bit distorted but Eastern Palearctic is above Australasian and Pacific Palearctic is above Oceania. PandaBearJelly

Is there an order to how biomes distribute or is it randomized? If you head east from Central Palearctic, will you hit the Eastern Palearctic biome first?

i have the fotsa animals spawning but i think the mod reduces the amounts of animal there can spawn, managed to find 2 wolves from the caninae mod and a stray elephant

Thanks for the bug reports, I'll look into them as soon as I'm back home.

Crabb Some testing was done and it is confirmed that the Biomes mod currently does not work with the 1.21 FotSA mods, specificaly tested with the FotSA: Caninae mod where it does not seem to spawn the FotSA Canines, only the base game wolfs and foxes.

Hello, was playing on the latest update on my server with the FSA: Caninae mod also installed (which also just recently updated to 1.21.1) and noticed that base game wolfs and foxes where still spawning even though they are supposed to be disabled by FSA: Caninae, not sure if this is a compatability issue between this mod and FSA: Caninae with the new update or not.

it looks like the new reed butterfly got missed (vanilla game:butterfly-reedbutterfly) it came up when I ran the unconfigured command. also 'floralzonescosmopolitanregion:coconut' but I can't tell if it's supposed to be like that or not, its the only one from floralzones that came up. 

Fuar Someone can correct me if I'm wrong, but 0,0 has nothing to do with where it is on the planet and is entirely based on spawn location. What you're looking for is the starting climate setting which defaults to temperate and a 45 degree latitude. AFAIK, each setting changes the starting latitude by 15 degrees north or south depending if you go warmer or colder.

Is it possible to change which biome you start a new world in? Is it always atlantic palearctic because that's 0,0 and it's the "middle" of the planet? 

Ok thanks very much for the PR, I've merged it ShaeTsu

Unfortunately I'm going to have to break compat with this release. If you're running 1.20 Vintage Story, please stick with 1.20.x Biomes. If you've updated to 1.21.x VS, please use 1.21.x Biomes.

ShaeTsu

Ok, I tried but something went wrong. My world was barren, I'm not sure how compatible this is with the FotSA mods right now. (Certainly not compatible with floral zones~)

AzuliBluespots I made the PR but it hasn't gotten a response yet, mod author is probably busy. You can get the changes here in the meantime: https://github.com/ShaeTsuPog/biomes/tree/master/biomes/assets/biomes

You'll need the updated biomes2.json out of /config and all 4 vanilla files out of /patches. Just unzip the biomes mod and replace the files in the correct spots. 1.21 changed folder structure from things like entities/land/ to entities/animal/mammal which broke the mod because it's still using the old structure.

I sorted many of the saltwater fish into biomes too, but it might not be that accurate, I couldn't find good sources on habitats for all of them. If you want better accuracy you should wait for the mod author to put out an update here.

ShaeTsu
So that's (probaly) why Terra Prety isn't spawning basically any critters.

Can you please share it?

Turns out the absurdly low animal spawn rates was mostly due to 1.21 changing the folder structure of vanilla animals, causing them to never spawn with this mod. I forked the repo and fixed it for personal use, I can make a PR with the changes if you're interested. I also took the liberty of sorting the different hares into different regions, because Wikipedia had nice maps showing where the different hare species can be found.

anyone got any idea how id add coral from the new update to the whitelist? ive been trying to figure it out but no luck. i can only figure out how to whitelist the fish from the update

Yeah, this mod is murdering animal spawn rates. I installed the Mobs Radar mod for further testing. Started a new world without Biomes, and I spawned in with about a dozen animals in my immediate vicinity. Turned Biomes back on, and generated another new world... zero animals. Flew around for about 20 minutes, saw 1 fox. 

Hello,

i've seen zero land animal, only one pack of water crocs from Legacy dino mods. Not a single rabbit, etc. Several days, hundreds of tiles, went to creative with /gamemode to move further and pass days. Still nothing.

Does this mod mess with spawn rates besides dictating where things can spawn? I installed this mod and ran around a world for 4 hours and saw a grand total of 1 moose. No wolves, foxes, hares, bears, pigs, deer, or fish. I'm using the full suite of FotSA mods and not seeing any of those animals either. I see that salmon are excluded from the starting biome, but that doesn't explain the lack of animals in general. 

Biomes and terrain-gen mods don't interfere with each other, so you're good to use Conquest Landform Overhaul and Biomes togehter.

You can teleport with the standard game admin commands as normal.

Yes that option just flips the layout of the biomes, it doesn't move your starting position. You'll need to travel or teleport if you actually want to be in the south.

Swipedude10

Does this mod work with Conquest Landform Overhaul? And, is there any way to teleport myself to a biome other then the one I spawn in?

Edit: I'm trying to flip north to south to spawn in a southern hemisphere biome but it will only spawn me in the africans biomes when I swap it - and i'll still be in the northern hemisphere.

Are there any errors in the log when you try to connect to a server with it installed?

Crabb Yes, but if I don't have it installed, then I cannot use it in single player...

Soap and Lye, Draconia, and Equus: Wild Horses mods have added support on their side. No need to update Biomes, just make sure you're using the latest version of those mods if you want to combine them with Biomes.

It's a server-side mod, you don't install it on your machine, only the server needs it. traugdor

I have an interesting problem with this mod. If I connect to a server that has it installed, it will not download. If I download the mod, it will not let me connect. I have never had this error with any other servers/mods before.

Anyone have an explanation?

Should be fixed now, thank you Kierantheking 

Sounds like a good suggestion HalfEnder776

I'll try and look into it for you

Could we get a setting that makes the biomes scale with the polar distance instead of the world size?

Or just some way to make the biomes repeat after a set number of blocks since by default reaching 102K blocks to get to the farthest biome would take forever.

it appears that for jalapeno in the code that their spawn zone for pacific nearctic is spelled neartic instead

Don't know what to say other than if this is happening, use the workaround. :/

I am having the same issue as AaronVonGraff. Tried to gen. a world with only this mod and it still threw the error. Only version of biomes in the mod manager, and there is only one biomes in the mods directory. Running on 1.20.12 (Stable) as well.

EDIT: deleted and redownloaded the mod. Error no longer occurring. Only difference was that I downloaded the mod's zip file and placed it in the mods folder manually, rather than using the "1-click install" button.

@Crabb no, I double checked. Works fine on 1.20.7 for me.

updated compatibility with Wildcraft from NiCH518

Do you somehow have the mod in your mods directory twice? AaronVonGraff

No idea how to fix this. I'm on 1.20.12 (Stable). I tried 1.20.15, 1.12.12, and 1.12.13 versions of biomes. Same issue on each.

There should be no conflict with Terra Prety

so feel free to use both.

Crabb also interested if you know whether this should conflict with Terra Prety or work alongside.  Thanks :)

Is this mod compatible with Tera Prety or should I only use one or the other?

Crabb also working for me! thank you!

Crabb This is working fine for me now, thank you

Biomes 1.20.15 adds experimental support for Linux. You have to be on VS 1.20.11 or newer for this to work. Windows users can ignore this.

Ok I'll see if I can find a way to detect Linux and fix the problem. If not, I'll put a workaround in the config file.

Crabb yep, i am also running on linux

Crabb I've post same issue on Github, my servers run on Linux, yes  (with Pterodactyl)

Are the servers that are having issues running on Linux by any chance ?

When generating a world and spawning in using the recommended settings, is there a recommendation for starting climate? I don't totally understand VS' spawning logic, but it seems like the world wants to spawn the player at 0,0 - which in my mind means it would be the center of the world/equatorial area. Is this the case? I would obviously prefer to start in a northern hemisphere, temperate climate for balance/ease of gameplay, but I'm not sure if this is messing with biome distribution in the world. Does that make sense? Thanks anyone who can answer!

having trouble with the latest version in VS 1.20.11 - got this in my server-main.log

(note: cleared my cache, modconfig, and all other mods to generate a new world)

p.s.: just want to say i love this mod and all the work y'all've put in to it! hope you're doing well!

1.20.14 version crashes our server on startup. We have 1.20.11 VS version.

Latest Biomes should be compatible with new and old Vintage Story versions.

I need Crabbs. Desperate for Crabbs.

Also... old world pond frogs had frogs spawning in the arctic. Not sure if that's intended or not. Also I wish I had Crabbs.

The private worldgen API has changed slightly which is causing the Harmony patch to fail. Crupette has given me a patch to fix the problem. When I get home in a weeks time I'll upload the fix. I'll try to make it backwards compatible with older versions of VS.

Esjitu Unsuprisingly, that's exactly the FIRST thing I did. While the world around the pregenerated area (What was loaded on my PC before uploading onto the server) loaded correctly but everything past that nothing loaded, hence why I was posting.

I pretty much gave up completely and have not used it for the playthrough because of it so I have shelved the mod for a good while.

Crabb

Same issue as everyone else is having with 1.20.11 update is needed to fix Biomes

Crabb
We have same problem after update! Please fix this! Thank you!

Mod seems to have issues with version 1.20.11 that released today.

Here's the finished patch for Florasphere:

crumps & Crabb

Oh dear

Latest unstable revision.  Biomes doesn't function at all.  Hopefully they will release it to stable soon cause the TPS gains are drastic.

12.5.2025 18:00:43 [Server Error] [biomes] An exception was thrown when trying to start the mod:

@Crabb Pretty sure its not really this mod.  Its a dedicated server running 8gbs of memory and I'm pretty sure the main culprit was all of the animal mods.  Seems to be stable now.  My comment can be disregarded.

Important: If you have a custom whitelist, please make sure its still working as you expect with /biomes whitelist when you upgrade from Biomes 1.20.12 or lower, to Biomes 1.20.13 or greater. You may need to change it slightly as it now expects the mod folder as well e.g. pachycephalosauria-* must be changed to pachycephalosauria:pachycephalosauria-*  or if you prefer, you can just put pachycephalosauria:* now and it will work for all entities in that mod.

Odd place to crash. Is it happening consistently? Whats your mod list? Turn on biomes debug in your user config file and check if there is anything else in the server main or debug logs. What happens when you run /biomes show ? Is your machine generally low on memory? Kasel

I'm going to enable this kind of whitelisting for entire mods in the next release:

{
"FlipNorthSouth": false,
"EntitySpawnWhiteList": [
"wethology:*"
],
"Debug": false
}

Not really sure if this is the exact cause but I've been getting OutOfMemory errors and this is the mod the error names.

Ok, thanks, Crabb.

Reading the details of that mod, it seems it does three things - adds more plants, changes the shape of trees, and changes the climate spawn conditions for trees. The only thing that is required for compatibility is patching in the biorealms tag to their new plants.

Whitelist is indeed for entities only. I actually need to double-check that it is still working.

Also you don't need to rezip the mod after changing it. The game will pick it up anyway. Makes life easier if you have to make a few changes.

Froshure

crumps Looking at florasphere_1.0.5.zip>assets>game>worldgen>treengenproperties.json, your concern is probably true. The only generation properties for Florasphere's flora are MinSize, MaxSize, Weight, MinTemp, MaxTemp, MinRain, MaxRain, MinFert, MaxFert, MinForest, MaxForest, MinHeight, and MaxHeight, suggesting that the mod doesn't have a built-in feature to separate flora into their real-world regions, like this mod has. In any case, however, no vanilla, Wildcraft, or Floral Zones flora should generate where they wouldn't without my Florasphere patch, as my Florasphere patch only targets Florasphere IDs.

Personally, it's too much commitment for me to fully integrate Florasphere with this mod (as I just need simple compatibility between this mod and Florasphere). However, you're welcome to install the patch I made and fully integrate the two mods, then upload it back here. Crabb probably would appreciate it too, assuming he decides to make the two mods compatible. Or I might change my mind and do this task myself; we'll see how I feel.

thanks again btw crabbs for doing this latest push to add more to the biomes mod. my server has gotten even more dynamic and better with having a lot of these working official now without having to custom patch :)

Froshure do you know or have experience in how this mod would mix when using this, floral zones, and wildcraft? I'm quite curious if they'd all consistently work together. at the moment biomes floral zones and wildcraft all play nice, but i'm curious if adding another like florasphere would throw patches of, say, spruce in the middle of new zealand.

Crabb, here is a compat patch for the Florasphere mod; it is to be added to your mod's biomes2.json. It allows all flora from that mod to spawn. I believe that mod has its own biome-sorting logic like yours has, so this patch just allows that mod to do its thing (though I may be wrong on this, in which case I or you can edit this Florasphere patch's spawn conditions to be stricter). I tried to use your mod's config file to make this fix, but couldn't get it to work (maybe the whitelist doesn't accept non-entities?). I tested my patch (albeit non-exhaustively), and it seems to work as expected. On a side note, I believe your biomes2.json misspells "shrubsaxaul" (it says "shrubsalaux").

Kasel I may be wrong, so someone correct me if I am, but from what I've found, to make a patch yourself, you can unzip the mod file and go to assets>biomes>patches, then make a new .json file. If you're unfamiliar with how to format the .json (like I was), you can use the preexisting patches as reference. Note that this method is only to patch entities (e.g. animals and monsters). To patch non-entities, such as trees and crops, you'd go to assets>biomes>config>biomes2, then add the tree/crop/whatever to the list, and its biome spawn conditions. Once you're finished making the patch, rezip the mod folder. Make sure that when you open the mod's new .zip, you see /assets, biomes.deps.json, biomes.dll, biomes.pdb, and modinfo.json (i.e. there should not be a biomes_1.20.12 folder when you open biomes_1.20.12.zip). I'm happy to help if you're confused.

Tall dry grass has been added GON

I've added a bit of documentation for the commands above in the spoiler. Note the base command has changed from /biome to /biomes

Just FYI, the latest versions of the Legacy of the Phanerzoics series work a lot better with Biomes now.

Not a bad idea Froshure

Vanilla salmon work, they just are not found in the starting location. Wilderlands Ethology is now supported by the latest Biomes release.

Froshure Kasel

Churburby I would also like to know or atleast have an example of the whitelist so I can add them myself.  No fish at all in my world.

Churburby How do I add the Wilderlands patch you made to my copy of the mod?

GodzillaFan_13 No, I think he's referring to a different collection of mods. This is one of them, for example: Bioregions: Eastern Palearctic Realm - Vintage Story Mod DB

This mod (Biomes) is compatible with the Floral Zones series.

hey, sorry if this is a stupid question (i am currently stoned rn so idfk if i'm computing right) but are the bioreigions mods referring to the floral zone mods correct?

Could you add a config option that automatically whitelists any mod that your mod doesn't configure, or a whitelist for whole mods (as opposed to just individual entities)?

Thanks Churburby

Wilderlands ethology compat patch;

New commands added

/biome entity

/biome unconfigured

/biome whitelist

These should help figure out if entities from other mods are working properly or not.

Started adding Fantasy NPC Series support - its not working properly yet tho - ok seems to be working. Goblins will be added next.

PhantomOfGrace usually if you're using worldgen mods (in this or Minecraft or similar) you should make a world in singleplayer with all your desired mods, THEN upload that world to the server. Letting the server generate a modded world for you tends to result in lots of issues in both these games.

Rustbound Magic compat is now built in Metroxide PhantomOfGrace

Yes it does support multiplayer. What version is the server? PhantomOfGrace

Is this mod not compatable with Multiplayer?

I have tried using it on a dedicated server I am renting but whenever it generates a world it doesnt spawn any plants at all. The world is just the terrain with a lot of standard grass and trader carts but no trees, bushes, or other vegetation spawn on the map. Even animals do not spawn (But the humans in the cart do). The log shows nothing but "Exception System.NullReferenceException: Object reference not set to an instance of an object" for both "PreDone" and "Vegetation"

Small compatibility request - the Dry Grass from https://mods.vintagestory.at/artofgrowing doesn't appear to spawn with this mod enabled

Metroxide I finally got it to work
The config .JSON file in %AppData%\Roaming\VintagestoryData\ModConfig needs to look like this

{
  "FlipNorthSouth": false,
  "EntitySpawnWhiteList": [
  "elemental*"
  ],
  "Debug": false
}

the entity name I used is just elemental with the star after it. Problem is they don't spawn all that often so getting one to spawn to check and confirm its working may take a bit.

I am also trying to use Rustbound Magic for this - would I just use the name of the json file for the entities?

I cannot, for the life of me get the Whitelist in the config to work. I have been trying to whitelist the Rustbound Magic entities so they can spawn but as I have no experience with VS modding, or coding in general I am finding myself unable to get it to work.
Does anyone have a modified Config file that is set up properly to whitelist Rustbound Magic mod?

All I have been able to go off of is Costardine / MaiaK's comments in both the comments here and for Rustbound Magic but am still ending up stuck.

You can only whitelist through the config. You'll need to look in the files for the mod you're using. The correct name will be in there. Metroxide

Can you whitelist creatures through the command, or just the config? How do you find out what the names required for entities are?

Awww man this game really seems not to be built for a lot of ocean in it which is a bummer ^^

Should be absolutely fine janchtexalibur

is this mod compatible with terra pretty? i like them to try on 1.20.9 update.

IMPORTANT  Biomes 1.20.6 should fix bowtorn and shiver. I HIGHLY recommend grabbing this update. You should see them start to spawn even without regenning a new world.

My personal worldgen settings would look something like this:

World height - 256 (default)

World width - 102k

World length - 102k

Polar-Equator distance - 50k

In my opinion this gives a good feel to the size of the world and the way Biomes lays itself out. Of course in your game you should make it however you want!

Adding that to the log would probably spam the logfile hard and hurt performance as VS does a lot of spawn checks. Sidfu

All Fauna of the Stone Age and Legacy of the Phanerzoix have Biomes support builtin, so no need to update Biomes mod as new versions of those mods are released. ThePhantomX64

I'll get those added Oghrind

Biomes are set for all chunks, not just ones containing land. HaraiseTenshi

any plans to update this mode with Fauna of the Stone Age new creatures and Legacy of the Phanerzoix new dinos that they made?

Crabb Hey, I noticed that bowtorns and shivers aren't whitelisted and don't spawn at all by default, but I was able to whitelist them so they'd spawn. Is this intended?

How does this mod work for a world created with Terra Prety or any kind of "real" earth as in half or more the surface Ocean?

Will it generate Biomes only for Chunks containing land or will I loose out on a lot of stuff if it just happens to be located entierly on the ocean?

florins
In assets/biomes/config/realms.json, the biomes are listed in order of appearance, from west to east. When the world is generated, the biomes engine will calculate, based on x-position, what biome a chunk should be generated in based on evenly distributing the biomes across the width of the world. (also based on latitude to determine hemisphere)

Typically, this means that a 1,000,000-block wide world will have 166,666-block wide vertical strips, going from -500,000 to +500,000, that are, in the north, PacNearc, AtlNearc, AtlPalearc, and so on. The biomes also overlap a little bit. However, if you copy and paste the realms in the file so that, for instance, NorthernRealms has 12 entries listed (the original six, but twice) then the northern hemisphere will be sliced into 12 slices by the engine, leading to a different realm every 83,333 blocks on a default sized world, with the Pacific being the center of the world. (I tested this on a 25k block world and flew around; there was a new biome every 2 kilometers)

So theoretically, to have a new biome every 50k blocks in a 1mil block world, you would need 20 items in each list. To start in the same place as normal (Atlantic/Central Palearctic), NorthernRealms should start with "pacific palearctic", and SouthernRealms should start with "oceanic."

It's badly worded. They mean setting your world length (north-south axis) to half of your world width (west-east axis) inside of your worldgen settings, so that your world is roughly twice as wide as it is high - similar to how a planet would look like proportionally if you were to flatten its surface out onto a square.

Is there a way to make biomes occur more frequently than once per world? Like have all express themselves every 50k blocks even though world size is 1 million blocks.  

how do we know if something was bloacked spawning? does the mod make a log saying xx  blocked spawning?

so i have been saving this question for a very long time , in your description it says to set the pole to equator distance to half the world height, and your example you use 1 million blocks tall but the game maxes out in the world setting at like 500 or whatever (not exact) Im just wondering what my pole to equator ditance should be for the default world height of 256 blocks??? sorry for the confusion.  

So, all the mods on the list, some are very old. Do they still work in 1.20? I am scared to test

Biomes doesn't touch temperature in any way. Check the biome you are in with '/biome show' command, it's possible you aren't in a biome that redwoods exist in.

With this mod enabled it seems my world setup ignores starting climate which I set to warm. It may be that trees I expect in a warm climate (mainly redwoods) are not spawning and that is by design but the temp seems more like temporate also
