I don’t keep up with the ‘No Mosaic Nude Patch’ mod for The Sims 3 as I did for The Sims 1 and 2. It’s just too much hassle when the mod has to be updated every time the game is updated. Of course, none of this faults on the creators – its just the way the game has to deal with mods. Anyhow, if you hit up Mod The Sims you can download and update your patch so it will work with the latest game updates as well as The Sims 3 Fast Lane Stuff. Thanks for the tip, Sims 3 Nieuws!

It works the same way, but it does not remove the effect, in fact, it delays the censor to 250ms.
The positive point of this one is that it’s dynamical.
So the creator does not have to update it for each patch, unless EA change how/when the effect is applied into the game in the core files.
