Every pack code: EP01 to EP21 and GP01 to GP12

Stuff packs start at SP01 and kits carry on the same SP numbering, with gaps in it, so you have to look a kit code up rather than work it out.

Edit traits in Simology with UI Cheats

UI Cheats for The Sims 4, the free mod by weerbesu, edits traits straight from the Simology panel.

  • A Sim in a bedroom with the Traits section of the Simology panel open and a right-click menu adding a trait

    Traits in Simology

    • Right-click the Traits bar to add one, or a trait to take it off.

    More on Simology

  • A Sim on a turntable in a character creation screen with a right-click Randomize option beside the confirm button

    Create a Sim

    • Right-click the confirm button to randomize the name, traits and aspiration.

    Every UI Cheats feature

What the mod can't do here

The mod never opens Create a Sim for you. There's no rename feature either, and no panel for body sliders or voice. The Simology age bar adds or takes away days, but it can't jump a life stage, so cas.fulleditmode stays a typed command. To set the mod up, follow the install guide, and every UI Cheats feature lists the other panels.

Frequently asked questions

What is the full edit mode cheat in The Sims 4?

Type testingcheats true, then cas.fulleditmode. Shift-click the Sim, pick Modify in CAS, and Create a Sim opens with every field unlocked instead of the short list you normally get.

Why is Modify in CAS missing from the menu?

You probably haven't typed testingcheats true, which is what puts the cheat menu on a shift-click. cas.fulleditmode only changes what you can edit once you're inside Create a Sim. Most reports of full edit mode not working come down to that missing first command.
