If you download a pirated version, once one of your Sims doffs their clothes, the pixelation will keep spreading until it covers the whole screen, making the game unplayable. In interesting related news, it seems as though EA has included an amusing intentional anti-piracy glitch in the game. Realistic junk is, sadly, not a feature of The Sims 4 - still very Ken and Barbie down there. You can download the nude mod right here, but don’t get too excited. I’m not sure why the makers of the mod used this picture to demonstrate it. There has been some kind of nude patch for every previous Sims game, and now the same can be said about The Sims 4!
For example, when opening the Random Sims Body Selector by clicking on a female. Random Sims Body Selector modifies bodies of randomly picked Sims in the world that matches the CAS Gender Settings of the clicked Sim. The Sims has always had an odd approach to nudity - nude models for all your Sims exist, they’re just censored by a pixelated filter when they disrobe, and modders are always quick to discover how to remove said filter. Every new Sim that is added to the world will follow what is set inside of the All Sims Body Selector. The Sims 4 may have eliminated certain longstanding Sims “features” like toddlers and the ability to drown your Sims in the pool, but the proud tradition that is the Sims nude mod is still very much alive.
