UPDATE COMPATIBILITY: This mod still works fine with the Feb 25th update.

Discord: I now have a Discord Server as an alternate place for support/feedback on my mods, and also for discussing furry mods in general.

This mod lets you easily and quickly add furry CC to sims to turn them into furries. You can either do this to individual sims manually, or automatically change all sims into furries. It can apply furry CC from several different mods, and has a variety of different furry species to choose from. It also has several settings to change how the furries are generated.

This mod is mainly intended to turn randomly generated townies into furries, but it can also be used to quickly furrify your own sims, quickly change existing furry sim's species or fur, or many other things. I recommend using my Furry Premade Sims mod to turn the game's premade sims into furries, as they are hand-made and generally higher quality than the furry sims this mod will make. Feel free to give feedback on the random sims as well, as this can help me make them look better.


Features/Usage:

• Interaction to instantly turn a sim into any of many furry species
• Interaction to turn a sim into an appropriate furry species based on other furry family members
• Option to automatically turn a customizable percent of unplayed sims into furries
• Options to customize what furry parts are applied to sims
• Options to customize what non-furry parts are removed from sims
• Option to keep furry children's parts consistent as they age up
• Option to ensure children of furry sims are furry and children of human sims are human
• Option to debug issues with furry eye presets
• Interaction to randomize a furry sim's fur patterns
• Interaction to update furry sim's appearances based on the preferences you set
  

The mod has 3 ways to turn sims into furries:

• Manually: From the Furrifier Menu, the "Change Species" and "Change Disguise" (for aliens) interactions will let you quickly change any sim to a furry from a list of different species. If you don't like how they look, you can change their species again, use the 'Randomize Fur' interaction to randomize only some of their appearance, or make specific edits in CAS.
• Automatically: If you turn on the automatic mode (using 'Toggle Automatic Mode' using the 'Settings' interaction in the menu), all non-furry sims will be turned into furries, and any newly created sims will also be turned into furries until automatic mode is turned off again. Be careful with this! Any unplayed sims you want to remain human or who are using furry CC from unsupported sets will be automatically furrified as soon as you turn auto mode on! Before doing so, use the mod's 'Debug' option in the menu to either mark them as already being furries, or as being exempt from automatic furrification.
• Commands: You can also manually furrify sims using commands. This doesn't require testing cheats to be on. Here's how the command works:
  

furrify - Changes the current sim to a random species
furrify [species] - Changes the current sim to the specified species
furrify [first name] [last name] - Changes the specified sim to a random species
furrify [species] [first name] [last name] - Changes the specified sim to the specified species


Advanced Usage:
For users who want more control over the randomization process, or want to make the mod compatible with unsupported furry CC, and can understand or learn JSON, there is an optional file called 'Custom Addons'. It contains instruction on how to make changes to the data file the mod draws from, allowing changes including changing how likely sims are to receive certain species, part, or colors, adding new species and parts, or removing existing ones.

If you make an interesting custom addon, I'd love to hear about it! I may want to add some of your change to the default file. You also have my permission to share it and post it wherever you want, no need to ask me. If it's SFW and I like it, I may also be willing to host it here as an alternative to my file.


Requirements and Compatibility:

Required CC:
  - Savestate's Furry Mod: A basic set of furry parts and patterns. Allows sims aged teen and older to be turned into dogs, cats, lizards, and sharks.

Optional Supported CC: These CC sets add extra options for the furrifier to use. They will be automatically detected, and you can see which sets you have installed in Settings > Manage CC.
  - Springroll's Natural and Sorbet Furry Recolors: Gives sims a much wider variety of fur colors they can have.
  - Cyangeom's Sims 4 Furry Mod - For Children, Toddlers, and Infants: Allows sims younger than teens to be turned into dogs, cats, lizards, and sharks.
  - Furry Mod Tails for Tailmod: Adds an option to use animated versions of SaveState's tails instead of the static ones.
  - Tomjj's Extra Furry Mods #1: Allows sims to be turned into pigs, boars, hippos, rhinos, elephants, and giraffes.
  - Tomjj's Extra Furry Mods #2: Allows sims to be turned into a variety of Avians.
  - Leljas' SaveState Addons: Adds an alternative for SaveState's furry heads. Only the SaveState addons are fully supported, not the Pokemod content.

The following Supported CC sets contain NSFW content, or required sets that contain that content, but the NSFW content iteslf is not used or required by this mod and can be easily removed (18+ Only):
Partially Supported CC: These CC sets will not be used by this mod, but the mod will not automatically re-furrify sims using them. More compatibility can be added by creating an add-on (see advanced usage).
  - Leljas's Mods
  - Tomjj's Pokemon CC
  - CC using furry head parts from already supported CC sets

Unsupported CC: Sims using CC from these sets may be re-furrified if the furrifier is in automatic mode and they aren't marked as exempt, but they might be able to be made compatible using add-ons (see advanced usage).
  - Other CC with unique furry head parts
  - Any CC without any furry head parts

Additionally, if you have Simply Invisible Clothes, it unlocks an extra option to automatically remove sim clothes for fully PG/SFW furry 'nudity'.

You can find a list of all the furry CC I know about here, and some notes I've written about using them here.


Installation/Updating:
1. Download Savestate's Furry mod

• Optionally, also any the Optional Supported CC listed above
  

2. Download the mod's file, unzip it and put the 2 files inside in your sims mod folder

• There are 2 files, they are both important and must be kept together in the same folder
• It includes a .ts4script file, which the game only checks for in your mod folder and its subfolders, not subfolders of those subfolders, so don't place the mod files more than 1 subfolder deep. Ex "The Sims 4/Mods/Sim Furrifier (containing the 2 mod files)" is fine, but not "The Sims 4/Mods/Furry/Sim Furrifier"
  

3. Make sure that "Enable Custom Content and Mods" and "Script Mods Allowed" are both checked in the 'Other' section of the game's settings
4. If updating, still download both files and delete the 2 you downloaded previously, but keep the automatically created furrifier_settings.cfg file in the same file to keep your settings.


Limitations:

• Ugly Sims: All parts are applied randomly, and sometimes they won't match well. This is mostly an issue for colors, as they will often won't look very good. Please report any obviously mismatched parts though and I may be able to fix them. The mod generates log files when it furrifies a sim, so send it to me and I'll try to fix it.
• Plant Sims: Plant Sims will briefly become normal sims in order to apply parts to them. This can lead to strange behaviors directly after they are furrified, such as needs or buff timers being reset.
  

Other Notes:

• Unlock Child Fur Setting: This setting allows child sims to use any fur patterns the adult sims use. By default, fur patterns applied with this setting on might be removed when you open the child's family in CAS. To fix this, follow this guide.
• Frame Restricted Heads: This setting partially fixes an issue with some of SoraFoxyTeil's heads, specifically the Dragon, Horse, Sergal, Dino, Canine/Fox, and Deer heads. Furry heads are restricted by the sim's body Frame to fix issues with seams, but these heads are mistakenly restricted by the sim's gender instead, so sims with body frames that don't match their gender will use the wrong heads. By default, the mod will respect this and give these sims the wrong heads, but you can turn this setting on to give them the correct heads. Note that unless you also fix the flags, the heads might not apply properly and can be randomly removed. To prevent this, you'll need to open each affected head in Sims 4 Studio, and go to categories -> Part Flags (at the bottom of the list), and make sure 'Restrict Opposite Gender' is unchecked and 'Restrict Opposite Frame' is checked.
  

Future Plans:

• Improved randomization, especially for fur colors (suggestions welcome!)
• Accounting for identical twins
  

• Bug fixes
• Randomization for Savestate muzzle shapes
• Replacing sim's pants to digitigrade-compatible versions
• Improved Plant Sims treatment
• Anything else that users suggest!
  

My Other Mods:

• Furry Leg Fix: Fixes sims having broken digitigrade legs when using vanilla nudity
• Furry Premade Sims: Turns all the game's premade sims into furries
• Simply Invisible Clothes: Adds a set of invisible clothes to allow for PG furry 'nudity'
