So you just finished creating your Sims in the Sims 4 and something doesn't look quite right. Maybe you were trying to make a Sim look like someone but got one of the details wrong. Maybe you gave them an annoying trait that you regret. Unfortunately, when you enter Create-a-Sim (CAS), it won't let you edit their traits or facial features anymore. Well, there is a cheat you can activate that allows you to fully edit your Sims after they've been created. This wikiHow teaches you how to use Full Edit Mode on the Sims 4.

How do you change traits in Sims 4?

The Sims specialist Kate Emerald says to enter the cheat code cas.fulleditmode to edit existing households. This allows you to edit everything about a Sim, including their traits, appearance, name, and age. If you just want to change their clothes, simply go into Create a Sim.
