Seeing red stripes on your Sim in The Sims 4 can be a jarring and confusing experience. This visual glitch often manifests as thin red lines cutting across the character model, particularly noticeable on the face, arms, or legs. While it might initially suggest a game-breaking bug or a horrifying fate befallen your digital citizen, the cause is usually far more mundane and easily fixable. This phenomenon is almost never a sign of a corrupted save file, but rather a technical hiccup related to how the game loads and applies textures to your Sim.
Understanding Texture Loading and the "Red Stripe" Glitch
The core issue behind red stripes lies in the game's process of loading assets. When you create or play a Sim, The Sims 4 has to pull various files from your computer's storage, including the Sim's body mesh and the texture files that provide their skin color, clothing, and accessories. A red stripe typically appears when the game fails to properly load the texture file. Instead of showing the missing image, the screen renderer displays the default underlying color, which is often a bright, flat red.
Common Triggers for the Glitch
Several scenarios can trigger this texture loading error. A sudden power outage or game crash while your Sim is active is a prime suspect, as it can interrupt the save process mid-texture-application. Similarly, installing a large number of custom content (CC) or mods at once can overwhelm the game's asset management system, causing it to load the wrong files or skip them entirely. Even a routine game update can sometimes corrupt these specific asset links, leading to the visual anomaly.

How to Fix the Red Stripes
The good news is that resolving this issue is usually straightforward and requires only a few simple steps. You do not need to delete your Sim or start a new game. The solution focuses on forcing the game to re-cache the correct texture files, essentially rebuilding its memory of what your Sim is supposed to look like.
Method 1: The Quick Save and Load
The easiest first attempt is to trick the game into re-applying the textures. To do this, move the afflicted Sim to a different lot. If the red stripes appear on a Sim in your home, drive them to a community lot like a park or a bar. Once they are on the new lot, use the "Save" option and then immediately "Load" that same save game. This process often triggers a hard reset of the Sim's visual assets, clearing the red stripes.
Method 2: The Delete Cache File (Clear Cache)
If moving lots doesn't work, you need to target the root of the problem: the corrupted cache file. The game uses these cache files to store temporary data for faster loading, and a damaged one is likely causing the texture error. You must locate and delete this specific file, which will force the game to create a fresh, clean version upon the next launch.

Step-by-Step Guide to Clearing the Cache
Follow these steps carefully to clear your The Sims 4 cache. Remember to close the game completely before starting.
| Ensure The Sims 4 is fully closed. Do not have it running in the background. |
| Open File Explorer (Windows) or Finder (Mac). |
| Navigate to your Documents folder. |
| Find the The Sims 4 folder and open it. |
| Locate the folder named Cache. |
| Open the Cache folder and select all the files inside (Ctrl+A or Cmd+A). |
| Press Delete. Confirm the deletion when prompted. |
After deleting the cache files, relaunch The Sims 4. The game will automatically generate new, empty cache files. Upon loading the affected household, the red stripes should be gone, replaced by your Sim's intended appearance.
When to Worry About Mods and Custom Content
If you are an avid user of custom content, the red stripes might be a direct warning sign from the game. Sometimes, a newly installed mod or a conflicting texture pack can interfere with the base game's rendering. If the Clear Cache method only provides a temporary fix, returning the specific CC responsible is the next logical step. Installing mods one by one and testing in between is the best practice to prevent these conflicts in the future.
