trying to create a tunning mod override

i tried to change a buff/tuning of a mod.

if i directly used sims4studio do that, its working.

but seems like that mod can detect file changes, prompt an alert that the mod maybe unstable.

i use windiff (tool to compare 2 files), and it show the difference more than a simple changes i made.

i guess sims4studio when saving, it rearrange the original mod and caused major changes even i only have a simple value changes in 1 of the mod tunning.

so i tried the _overrides folder approach, after search on the net.

use the studio, create empty package, add a new/empty file with the supposed matching type.

paste the xml i extracted from the original mod tuning, change the value in there. save the package.

when run the game, err! better-exception pop the issue into browser, and i can't play the game with my changes.

i guess my override is not done properly.

does the new override tunning need different id/naming, or more?

its xml content practically the same as original, just 1 of the value i want to change.

Better exception error is because you done something wrong in your tuning file.

I have never had sims 4 studio make changes to tunings on it's own.

What ever gets placed into the mods folder overwrites the games files.

The override folder is for overriding other mods, like say someone has a walk by mod, instead of actually modifying the package i can extract the default
walkbyDirector_CityLife_SpiceMarket make my own changes, then i would place it into the override folder so my walkbyDirector_CityLife_SpiceMarket gets loaded first.

Sometimes when the game updates EA change how tunings have to be formatted. If you are using tuning from before an update, you should extract a fresh copy and make your changes in the new file to make sure it is format correctly.
Sims4Studio will not make any changes that you did not make on purpose.

Another thing to add, you mentioned you made changes to a buff depending on what you changed that may need to be reflected in the sim data as well.
We can only guess what changes you made as you haven't shared the original buff and your modified one.

If you changed the mood type that needs to be changed in sim data.

You should use https://tdesc.lot51.cc/ as you can import your own tuning files, if a tuning requires sim data you can download it with out you having to edit it by hand.

it doesn't worked as expected.

the last test i did:
- i created folder "_Overrides" within mods
- edit Resource.cfg to have:
Priority 500
PackedFile *.package
PackedFile */*.package
PackedFile */*/*.package
PackedFile */*/*/*.package
PackedFile */*/*/*/*.package
PackedFile */*/*/*/*/*.package

Priority 1000
PackedFile _Overrides/*.package
PackedFile _Overrides/*/*.package
PackedFile _Overrides/*/*/*.package
PackedFile _Overrides/*/*/*/*.package
PackedFile _Overrides/*/*/*/*/*.package
PackedFile _Overrides/*/*/*/*/*/*.package

- created package file contained the tuning and data file. their contents all same, except the buff duration number.
- i even renamed the package file same as the original.

what i get in-game, when i tried to use mccc cheat to add the buff, it shows up 2 of them!

the only way worked is forget about the override folder, directly edit the original mod buff.
