A fresh Sims 4 loading screen, every time you play.

TS4RLS picks a random image from a folder you choose and installs it as your Sims 4 loading screen mod — a single self-contained app with a GUI and a headless mode for unattended use.

What it does

Random, every launch

Drop PNG/JPG/BMP/WebP/TIFF images into a folder. Each run picks one at random (or two, in vertical mode) and splices it into a real Sims 4 loading-screen .package file.

Vertical combine mode

Pair two portrait-oriented images side-by-side into one landscape loading screen automatically — great for phone-camera photos and portrait art.

GUI or headless

Double-click for a desktop GUI, or run with --generate for a silent one-shot — the same single executable does both.

Steam artwork included

A full set of Steam library artwork (capsules, hero, logo) ships with the app — see the Steam guide.

Settings that follow you

Configuration lives in your OS's per-user app-data directory, not next to the executable — move or update the app freely without losing your setup.

Safe by default

Only ever writes a single .package file to your Mods folder — no auto-launching your game, and it warns you if it finds a leftover mod from an older version before generating a new one.

How it works

  1. 1

    First run

    The Build tab asks for your images folder and Sims 4 Mods folder, then saves your settings for next time.

  2. 2

    Generate

    TS4RLS scans the images folder, picks one (or two) at random, resizes/centre-crops it, and splices it into the loading-screen template.

  3. 3

    Install

    The finished .package is written straight to your Sims 4 Mods folder as TS4RLS.package.

  4. 4

    Play

    Launch Sims 4 yourself and enjoy a new loading screen. Run it again any time for another random pick.
