Mods Folders & The 50/50 Technique
The Sims Crew confirmed in a message on The Sims Discord that this Sims 4 Replace will have an effect on mods:
This replace is anticipated to have an effect on mods and we advocate you again up your saves and handle your mods/CC rigorously.
Like most different updates, mods have an opportunity of breaking, particularly if they alter a characteristic that has been adjusted within the replace. Customized content material is commonly utterly fantastic, however recordsdata can at all times corrupt or go unsuitable ultimately. Because of this, whereas it could appear tedious, the 50/50 technique is one of the simplest ways to seek out any points which have popped up in your recreation which are stemming from damaged or corrupted mods and customized content material.
The 50/50 technique is a method of organizing and testing mods and customized content material to trace down a selected file or recordsdata which are inflicting a bug or error in your recreation, or are inflicting it to not load or crash. Ensure that to again up your saves, mods, and tray folders previous to this!
For a extra in-depth information to the 50/50 technique, ThatSimsLady has damaged it down beforehand and supplied a guide that walks you through it, however right here’s a common diagram from Sims After Darkish.

Principally, the 50/50 technique is once you cut up your mods folder down the center, testing every half (Say, Half A and Half B) individually to rule out points. For instance, if the error or bug in questions persists in Half A however not Half B, then you understand that the difficulty is held in Half A. You’ll be able to safely kind away Half B after which cut up Half A and take a look at both half, and so forth and so forth.
This could enable you monitor down problematic recordsdata pretty simply. And I’ll say that no person likes doing the 50/50 technique since it could possibly take a very long time, particularly should you play with a great deal of mods and customized content material, however is an excellent method to ensure your recreation is in wholesome situation and none of your saves are in danger.
Normally, mods that break throughout updates are UI Mods and Gameplay Mods.
Gameplay Mods usually add or change options in The Sims 4, and lots of comprise two recordsdata; .package deal and .ts4script recordsdata. Whereas not at all times, these mods are liable to breaking with updates and must be eliminated and individually examined, or solely up to date/added again in as soon as the creator has stated it’s secure.
UI Mods are any mods that change the person interface, just like the menus surrounding your display screen in Reside mode and Construct mode, or your columns in Create-A-Sim. Probably the most generally used UI mods embrace UI Cheats, Extra Columns in CAS, and any Consumer Interface Substitute mods. Whereas it’s not inherent that they are going to break, they’re normally the primary to interrupt throughout any replace.
Additionally, at all times delete your thumbcache file. It regenerates each time the sport launches, and will at all times be deleted whereas altering your mods folder in any method, particularly should you’re doing the 50/50 technique.
Additionally it is really helpful to check mods with new updates in a totally recent save file, to keep away from corruption but in addition since sure updates solely work with newer saves.
Different Factors of Word for Mod Group & The 50/50 Technique
- An excellent rule of thumb is to maintain all mods separate from customized content material. Customized content material can break, however it is rather unlikely since they typically do not change something concerning the video games capabilities or options, and as an alternative simply add new belongings.
- You can not separate mods from their additional recordsdata. In case you have two recordsdata for a mod, like “MODNAME.package deal” and “MODNAME.ts4script”, these two recordsdata should at all times be in the identical folder to operate.
- Mod dependencies are bigger mods that do not do a lot on their very own, however are required for others to operate. Many smaller mods require issues like Lot51’s Core File, the XML injector, Lumpinou’s Temper Pack, and lots of others that should be examined alongside mods that require them.
- These might also should be up to date on their very own.
- Some straightforward methods to arrange your customized content material and mods embrace…
- NOTE: Script mods can solely be one folder deep, whereas customized content material can go round 5 folders deep.
- By Kind: You’ll be able to manage by the kind of asset, space of the sport, and many others., and it actually simply will depend on how detailed you wish to go.

- Ex: Putting hairs in a folder referred to as “Hairs”, “CAS_Hairs”, “CAS”, or much more detailed folders like “Hairs_Infant_Fem” or any variant.
- You may as well make an general “Create-A-Sim” folder, after which add particular person folders for issues like hair, make-up, and many others.

- By Creator: Whereas this will get semi-tricky when creators have collaborations, it may be simpler to keep away from duplicate mod recordsdata by sorting by creator, particularly in case you have plenty of objects from a choose few.

- Ex: “Creator1”, “Creator2”, “Creator3”.

- In the event you solely have a handful of things from a sure creator, you may as well alphabetically kind. Like “A-D”, and embrace all creators with names beginning with that vary of letters.
The most important level is that your group technique is sensible to you, and also you alone! So long as you will discover the place you place issues and troubleshoot your
