Step-By-Step Instructions for Editing Sims

Follow this walkthrough to edit any Sim in your game:

1. Enable Cheats

First, you need to activate testing cheats. This grants access to special commands that let you bend or break the rules of the game.

• PC: Press CTRL + SHIFT + C
• Mac: Press CMD + SHIFT + C
• PS4/PS5: Press all 4 shoulder buttons at once
• Xbox: Press all 4 shoulder buttons at once

This brings up the cheat console box. Next, type testingcheats on and press enter to enable cheats.

2. Enter CAS Full Edit Mode

The special command you need is cas.fulleditmode. This removes all locks in Create-A-Sim so you have unlimited customization options for any Sim.

After enabling testing cheats, type cas.fulleditmode into the console and press enter again.

3. Select a Sim to Edit

Now comes the fun part – picking a lucky subject for your makeover magic!

To load any Sim into CAS, press and hold Shift on your keyboard. Then simply click on them (left click with mouse or A/X on controller).

When the menu pops up, choose "Modify in CAS."

Ta-da – CAS opens up with that Sim loaded and ready for editing!

4. Customize to Your Heart‘s Content!

Go wild and customize their:

• Body features and body type
• Makeup and hair
• Clothing style
• Personality traits
• Aspirations and skills
• Relationships and family ties
• Name, voice, preferences

Everything is editable with no restrictions in CAS fulleditmode. So sprinkle some magic and give random townies a long overdue makeover!

5. Save Your Masterpiece

Once you finish customizing your randomized masterpiece, there is one crucial final step – saving your changes correctly.

Do NOT create a new Sim or clone the existing one. Simply click the checkmark in the top right to save edits and exit back into gameplay. This permanently updates that Sim with all changes applied.

Now sit back and watch your personalized Sims come to life!

Who Can You Edit with This Cheat?

The CAS full edit unlock lets you modify and customize:

• Townies – Revamp procedurally generated NPCs wanderings the neighborhoods
• Pre-Made Sims – Tweak starter families like the Goths or Landgraabs
• NPCs / Background Characters – Customize special NPCs like Father Winter

Essentially every Sim that exists in your save file can be edited – playable or not. The only exceptions are Sims stored in your library that have not been placed into the world.

So feel free to give the townies roaming around a fresh new look tailored to your preferences. Or fix any odd randomized outfits the game creates.

According to many players, editing townies is the #1 use case since their wild fashion is notoriously questionable!

Saving Your Edits Correctly

When finished customizing a Sim, it‘s vital that you save properly so changes remain permanent.

Exit CAS by clicking the checkmark icon. Do NOT clone or create new Sims. Overwriting the original is how edits are applied permanently when you return to gameplay.

If you save incorrectly, the game will discard all changes or duplicates won‘t retain custom tweaks. So remember – exit normally to make all CAS edits "stick."
