Getting Started with The Sims 4 Modding

Enable mods, find the Mods folder, install MCCC + CC, and manage the patch cycle

The Sims 4 modding has two distinct categories: CC (Custom Content) for visual additions and script mods for gameplay logic changes. Both go into the same Mods/ folder, but they behave differently. This guide walks the standard install.

Step 1 — Enable mods in game options

In-game: Options → Other tab. Check:

Enable Custom Content and Mods
Script Mods Allowed

Restart the game. Mods are now active.

Step 2 — Find your Mods folder

Documents/Electronic Arts/The Sims 4/Mods/

Everything goes here. The folder has subfolders for organisation if you want, but the game scans recursively.

Step 3 — Install script mods

Three near-universal script mods:

MC Command Center (MCCC) — comprehensive game control. NPC randomisation, story progression, age controls. Most-installed Sims 4 mod historically.
Wonderful Whims (or Wicked Whims for adult content) — relationship and attraction overhauls.
Better Build/Buy — build-mode QoL.

Each is a .zip or .package plus .ts4script. Extract into the Mods folder.

Step 4 — Install CC

CC packages are visual additions — hair, clothing, makeup, furniture. Drop .package files into the Mods folder.

CC creators are on Tumblr, Patreon, individual sites, and CurseForge. Quality varies dramatically. "Maxis Match" CC is designed to fit vanilla aesthetic; "Alpha" CC is more realistic.

Step 5 — Manage with a CC organiser (optional)

For large CC libraries, Sims 4 Tray Importer and CC Manager help organise and identify content. CurseForge's launcher is emerging as a more structured option.

Common gotchas

Mod doesn't load. Script mods must be enabled in Options. Confirm both checkboxes.
CC doesn't appear in Create-a-Sim. .package not in Mods folder, or game wasn't restarted after install.
MCCC missing after EA patch. Update MCCC. Deaderpool (the MCCC author) updates quickly after each EA patch.
Game loads slowly. Large CC libraries (thousands of files) extend startup time. Cull periodically.
Conflict between two script mods. Read each mod's compatibility notes.

The Sims 4 modding scene is fragmented (no central Workshop) but enormous in absolute terms. Once you have MCCC plus a curated CC set, the modded experience is substantially different from vanilla.
