Troubleshooting

Fixes for common problems: a mod missing in-game, a blank catalog thumbnail, a disabled Download button, stretched images, and lost projects.

Here are fixes for the most common issues.

My mod is not showing up in-game

Did the game just update? The Sims 4 turns custom content off after every patch. This is the most common reason a mod that used to work stops showing up.

Check that custom content is enabled. Go to Game Options → Other, confirm Enable Custom Content and Mods is checked, and click Apply Changes. A TV Channel that adds a new channel also needs Script Mods Allowed. Every other project type is a plain .package and does not.

Restart the game. Mods load at startup, so quit and relaunch completely after adding a file or changing settings.

Check the file location. The .package file must be inside Documents/Electronic Arts/The Sims 4/Mods (or a subfolder). Make sure it is not still inside a zip archive.

Look in the right catalog section. Wall Art, Rugs, Vases, and Tables are in Build/Buy (vases under Decorations → Sculptures). Nails, Earrings, and Glasses are in Create-a-Sim under Accessories, and Tattoos under Tattoos. Eyes are also in Create-a-Sim: Contacts under Makeup → Face Paint, Eye Colors in the Eye Color picker. A TV Channel is not a catalog item, so check a TV's channel list.

The catalog thumbnail is missing or shows a grey box

The thumbnail is embedded at export time. On Auto, Llama Builder renders it from the 3D preview, so downloading again regenerates it. If it still looks wrong, switch to Upload and provide your own image.

The Download button shows a lock

The Download button needs a Creator subscription. If it shows a lock:

Sign in, then subscribe from the plans page.
If you already subscribe, try refreshing the page.
Check that your subscription is still active under Account settings.

My image looks stretched or cropped in the 3D preview

Adjust Image Fit. Contain keeps the whole image visible (with letterboxing); Cover fills the canvas but may crop; Custom lets you position and scale it yourself. See Image Fit.

The rug shape mask looks wrong

Check that the right mask type is selected and adjust its sliders (Ellipse Radius for oval, Corner Radius for rounded). Some masks only show once you move a slider off its default.

I lost my project

Projects autosave. Open the Projects drawer to find recent work. If you were signed out, the project lives in your browser's local storage, so clear browser data cautiously. Signing in syncs projects to your account.
