Tutorial + Mod (Requested) - Motives Decay Rate (Patreon)

I was requested a mod to make the motives decay 15% slower. I already have a mod to make motives decay go faster or slower (in mine, it depends on the motive, since I use a custom time speed and balanced it to my taste and needs, I never shared that one), and this is by far one of the easier mod you can make. So I'm going to make a step to step tutorial into making the mod from start to finish.

Let's open Sims 4 Studio and create an empty package under tools:

Give the package a name, click on save and it will open the empty package, again under tools let's select "extract tuning":

Now, I know what I'm looking for, so I can just type motive_ in the bar.... If you don't know what you're looking for when making a mod, then you'll have to make some research...

I selected all the base motives I want to change and imported them into my package, and you'll see that every single one of them has a tuning file and a SimData file:

Now, when this happens and you want to change something, you need to check also the SimData file. This because a mis-match between the two can cause problems that can vary from a mis-matched information in the UI to a game crash... for example if I were to change the max vale tuning (and we're NOT):

(This is the max value this statistic can reach, it can go from 100 to -100) then I'd need to change it both in the SimData file and in the Tuning file:

Now, this was just an information, because the value we need to change is the decay rate:

So we can go and check that this value is not present in the SimData file, and after we're sure that it's not, we can just remove them from our mod:

at this point, we can go back to our decay rate and do some math...

After you changed the decay rate to the desired value, you can save the package and you're done. This all a mod like this one is about.

The decay rate in the following mod is decreased by 15% for all motives.

The decay rate in my private mod is decreased or increased on a singular motive base.
