Add effect or object (eg flies & stink or fxpV5) around body

Timezones and low modding population, give it time for someone to respond.

Are you saying you made a custom animation and want some effects to play while the animation runs? Follow this post then: sims4studio.com/post/66519/thread
You need to go to your Clip and find where it says "Events". Click Edit Items, find Effect in the dropdown list, click add, then fill out the info.

If it is not a custom animation, the other option is to apply it through a buff.

You'll need to figure out how you want the buff to apply during the animation/interaction you want. It can run when the interaction does, or you can apply it through other means.

Once you figure out how you want the buff to be applied, grab the name(s) of the VFX you want, then make the buff with a slightly similar layout to this:


You can follow these tutorials to learn how to make buffs, interactions, and read the TDESC.

Though if you're trying to replace the generic hygiene VFX when sims get stinky, you need to do that a different way through file overrides, if it's even possible as VFX is tricky. You would need to track down the x2 moodlet and see if it uses the same VFX method as shown above, and if it does then you need to copy all of your code and paste/replace over the original (or only some of it, depending on what you want to do). If it doesn't, that means the VFX is applied in a different way.

How you apply the buff, it's duration, what removes it, etc. is what determines how long the buff stays. If you want it to stay forever you need make sure the buff never expires, isn't removed by showering, etc. You just need to read the TDESC for file format and study other similar buffs to get it to stay.

If all you want to do is add an effect when you have the filthy buff, you just need to add the highlighted piece of code and change the effect name and the bone name(that's where the effect will play)

thanks guys, i am on it. i had a first look at the patrion tutorial and i am going to try out sigma's advice to get into the jist of things. From there, i will see where i go. thanks guys. I will report if anything goes wrong. Cheers. 03stevensmi

Use the layout I suggested previously because that layout actually supports multiple effects. See where it says <U n="play_multiple_effects">?

<V n="vfx" t="play_multiple_effects">
