This mod makes domesticatable animals' overall breeding time configurable using Configlib, adjusting their time between pregnancies, gestation time, and hours until children become adults, allowing faster or slower generations.

 

This is useful for shorter lived worlds which would otherwise not reach the later/more convenient animal generations, or to slow reproduction for a more challenging playthrough.

 

By default, harvestable drops for supported animals are also reduced based on breeding time. This only affects reduced breeding time settings. If breeding time is increased, instead of reduced, the standard drop rate will be used.

 

By default, breeding times are all halved, but it's expected that you would adjust these as needed per animal/mod.

Supported vanilla animals:

 

  • Chickens
  • Goats
  • Hares
  • Pigs
  • Sheep

Supported mod animals:

 

 

Note that this mod may be updated frequently to keep up with referenced mods

To do:

Extend mod support:

  • Wool & More [issue]: (reduce wool drops for vanilla and modded animals, add settings for deer breeding rate)

Not planned:

 

  • Reducing non-harvesting resources from animals (ex: milk, wool from shearing)
  • Altering stats for non-domesticatable animals

Don't know if this needs to be addressed, but I've got the mod downloaded on a personal server, I change the default settings of the mod, save, return to the server, and the settings have return to the original defaults. I don't know if the changes are happening and I'm not seeing it or the changes are not saving.

💬 Billiam , Sep 25th at 4:39 PM

Should have an update soon. Waiting for the mods in that series to settle down

Getting a few errors with Spheniscidae, Tenth Architect mentioned having removed "a couple unnecessary behaviors from the eggs, that might have broken the patch from another mod".

Oh heck yeah, this is the kinda notification you love opening the page to.
Thank you for the update!

💬 OscarK, Sep 14th at 7:57 AM

thank you so much for the update!!

💬 Billiam , Aug 28th at 1:45 AM

Mod will be updated, but not this week!

💬 NylonCat, Aug 27th at 12:55 AM

Tl;dr: Current mod version no work in 1.21 (duh), need to wait for update, praise overlord Billiam

This is admittedly one of the more difficult mods to troubleshoot but after playing with version 0.0.22 (for 1.20.12) in the new 1.21 release build, i can pretty confidently say that it's not working anymore.
The mod shows up as loaded and can be configured via the configlib menu just fine, but none of it takes effect anymore. I've tested this over the span of several hours with bighorn sheep, valais goats, the new hares (brown and river specifically), chickens and pigs. Young animals take ages to grow up and pregnancies barely progressed, while the config settings were set as low as 0.05 for some of them, so i'm guessing it is taking vanilla values instead and completely ignores the mod.

An update would be very much appreciated, though i'm assuming there might be a fair bit of work for a major version change.

💬 Gooish_Die, Aug 26th at 9:23 AM

ValariaLyte That's the question of the century for MANY mods.

💬 ValariaLyte, Aug 26th at 1:26 AM

Will this be updated to 1.21?

💬 Billiam , Jul 13th at 5:17 PM

Willobe Should be fixed!

Voilyn What do your settings look like? Are you sure you didn't set them to a lower breeding speed? Higher is slower here.

💬 Willobe, Jul 12th at 3:46 AM

@Equus setting causing an error, they changed the structure in wildhorse.json Billiam

💬 Voilyn, Jul 8th at 6:32 PM

I've changed the settings on the vanilla animals to breed at max speed. My muskox got pregnant and it still said x out of 76 days. Didn't get any shorter

💬 Billiam , Jun 26th at 4:37 AM

Anotzibartschad Thanks! Should be fixed

💬 Anotzibartschad, Jun 25th at 4:56 PM

Hey, this mod is having issues with your mod. They probably changed the file structure or something like that. It's one of the legacy of the phanerozoic mods. Other than that, great mod!

💬 Billiam , Jun 12th at 9:43 PM

Kyrju Where did you see that configlib was not compatible with 1.20.12?

💬 Kyrju, Jun 12th at 6:28 PM

It is really puzzling why coniglib is not updated to version 1.20.12 when other mods that depend on this mod like this have this version 1.20.12. I have the latest version VintageStory 1.20.12 I would like to download this mod but I will not be able to configure it because Configlib does not work for me because it has an old version :(

💬 Billiam , Jun 10th at 5:17 PM

Aniriteron These are currently listed under a single "Legacy of the Phanerozoic breeding rate" config item.

💬 Aniriteron, Jun 10th at 6:01 AM

i may be stupid, but when i open it up, it does not show any of the Legacy of the Phanerozoic animals?

💬 ssunny2008, May 22nd at 12:48 PM

Billiam Thanks for the quick answer!

💬 Billiam , May 21st at 5:04 PM

ssunny2008 Those 0.5 multipliers mean that the time has been reduced by 50%. If you wanted to use the default vanilla times, you'd set those to 1.0 instead

💬 Billiam , May 21st at 5:03 PM

BrotherMorse No, portions are not reduced

💬 ssunny2008, May 21st at 11:39 AM

Hi there,

just a short question... are those 0.5 multipliers the default time the game / several mods are using or is it already reduced by 50% at this point?

Thanks in advance and thanks for the mod. Helps a lot if i don´t have to reconfigure dozens of Jsons. ^^

💬 BrotherMorse, May 21st at 2:40 AM

Does reduced breeding time also reduce the amount of portions an animal needs to eat?

💬 Vigilance, May 18th at 2:15 AM

That's fair, I dunno, I don't care much about generational increase compared to... not needing to wait for a century to get eggs from them haha. I'll just stick to chickens I suppose.

💬 Billiam , May 17th at 3:54 PM

> Any ETA on the FOTSA pack with the emus etc? 

I'm not sure. From the description, emus are not domesticatable, and don't increase in generation (which is the point of the mod), but you can breed them by feeding from a trough, so they're in a weird gray area as far as the mod's purpose goes

💬 Vigilance, May 17th at 2:17 AM

Billiam I'm personally modifying values individually. I would be heartbroken if my modifier for some of the for-fun animals would be merged with my modifier for "useful" animals.

 

Any ETA on the FOTSA pack with the emus etc? I just looked at some of these Emus having about 80 days left until they'll breed haha

💬 Billiam , May 14th at 7:26 PM

Question to anybody using this mod: Are you customizing the Fauna of the Stone Age mod values individually, or should those mods' settings be grouped together into one setting, like Legacy of the Phanerozoic?

💬 Billiam , May 14th at 4:33 PM

nomashawn If you have ConfigLib installed, you can access the settings by clicking the "Mod settings" button in the pause/escape menu.

💬 nomashawn, May 14th at 6:16 AM

Hi! Love this mod a lot, it's working very well :)

 

I'm new to modding vintage story & mods in general. How do I access the configuration panel? thank you <3

💬 MyNameWill, May 2nd at 4:53 PM

Thanks homie, you're awesome

💬 Billiam , May 2nd at 4:32 PM

MyNameWill I'll take a look

💬 MyNameWill, May 2nd at 4:28 PM

Thank you for adding this mod! Makes my life so much easier lol. I don't want to be that guy, but do you plan on adding support for the various Dinosaur mods? No worries if not, I just think it'd be neat!

 

💬 James122603, May 2nd at 5:03 AM

Billiam Thank you very much!

💬 Deathstrich, May 1st at 9:31 PM

Billiam Thanks a lot :)

💬 Billiam , May 1st at 4:19 PM

James122603 Deathstrich Sure, will be added in the next release

💬 James122603, May 1st at 4:03 PM

Might I suggest of adding support for the Monoceros mod? I shall suggest vice versa to them as well.

💬 Deathstrich, May 1st at 2:58 PM

Could you add support for More Animals mod? Thank you in advance.
