The Sims Team acknowledged that their new “Dust System” that came with The Sims 4 Bust the Dust Kit needs a few tweaks. They promised that the update that will fix the rapid dust accumulation is planned for release later this month, however PC / Mac players already have a quick solution thanks to the talented modding community!
Modder simmytime came up with a Mod solution that will significantly slow down the dust accumulation period, changing it from a few hours to a few days:
Much slower dust accumulation
The EA default is ridiculous. Within 5 hours my Sim living alone had a dirty house! So with this mod, dust will collect much more slowly – the time they take to accumulate has been more than halved. Dust starts to gather at around 3-4 days, which I think is much more realistic. It would also take a good week and a half for your home to become filthy: again, much more realistic.
There’s another small mod included in the linked page below which completely gets rid of dust bunnies and their spawning!
To install these mods simply extract the .zip files to Electronic Arts > The Sims 4 > Mods folder and ensure you have Mods / CC enabled in your game options!
