Sweat When Workout (Collab with K_Delk)

K_Delk recently released a custom overlay of sweaty stains on clothes. I liked the idea, so I created an add-on mod that applies these stains after a Sim exercises, climbs rocks, or does fitness activities, for approximately 40 minutes. However, the stains aren't applied to topless Sims because they are made specifically for clothing.

A Sim also receives a random reaction moodlet, which depends on their personality.

INSTALLATION

CC by K_Delk IS REQUIRED FOR THIS MOD! But you can use this CC standalone without my part.

Put both the CC and the mod in the Mods folder

F.A.Q.

No sweat stains / moodlets?

  • You didn't install Lot51 Core Library correctly

  • You didn't install CC by K_Delk

  • A Sim's training lasted less than 40 minutes

  • A Sim is topless

  • Some clothes can hide an overlay, just experiment with different tops to find out the cause

DOWNLOAD

Both files are required!

Thanks! I haven't talked with KDelk recently so I didn't know she decided to upload on Patreon too. I'll update the link

I love this but I feel like it's occurring way to often. Maybe it can be tweaked so sims work out have to be going on for much longer for it to occur.

I would imagine the Buff Tuning for the string titled Sweat_When_Workout_Delay_Buff is where the time is set. You need to open and edit in Sims4Studio (don't worry it's just text and is easy, just make a backup first just in case) Assuming the 45 in that string is the delay. If that is the case is there an easy way to make the time variable in a future release?

Try clear the cookies or another browser, there is no another source of this CC

Boosty still broken 2-3d later. I'm not comfortable removing all my firewalls to see if it loads that way. Too bad the creator doesn't seem to use anything else. I would've liked to use their mod.....or any of the cc I just discovered from them.

It works perfectly fine for me, I just rechecked it. It's not about firewalls, but you can try another browser or clear cookies. I don't like Boosty either, though it's a decision of each creator what they'd like to use, especially since it's tough to maintain all content on multiple platforms. For the same reason I publish only on SFS

Just out of curiosity; For how long will these stains remain present after you stopped working out?

S
SonozakiSisters · August 3, 2026

A couple of hours

The boosty link for the sweat cc refuses to open or load. I tried with a different browser, and it made me sign up for Boosty. Once I did that, after clicking the download button, I got an error page, so I'm unable to download the cc for this mod. I tried both Google Chrome and Microsoft Edge.

Seems to be a server error on the Boosty side. Try a bit later, and you don't require to have an account there to download a content

Does this cause issues with Wicked and or Wonderful Whims? Both have a sweating system but for skin yet not clothes so I'm curious

S
SonozakiSisters · August 1, 2026

No, both mods can work at the same time. The WW's sweat is applied directly on a Sim
