This guide will walk you through the process of adding custom models, ensuring you have the right tools, understanding the necessary steps, and troubleshooting common issues.
Prerequisites: Tools and Knowledge
Before you dive into creating your custom models, ensure you have the following tools and basic knowledge:
- Blender: A free and open-source 3D creation suite. Familiarize yourself with its interface and basic functionalities.
- Sims 4 Studio: A free, user-friendly tool designed to help create and package custom content for The Sims 4.
- Basic understanding of 3D modeling, UV mapping, and texturing.
- Knowledge of The Sims 4's package file format (.package) and its structure.
Preparing Your Custom Model
Once you have your 3D model ready, follow these steps to prepare it for import into Sims 4 Studio:

- Export your model from Blender as an OBJ file. Ensure your model has a proper UV map and is optimized for game use.
- Create or obtain a suitable texture for your model. The Sims 4 uses DDS format with 2048x2048 or 1024x1024 resolution.
- Prepare any additional resources, such as thumbnails or icons, required for your custom content.
Importing and Packaging with Sims 4 Studio
Now that you have your model and resources ready, use Sims 4 Studio to package your custom content:
- Launch Sims 4 Studio and select "Create New Project". Choose the appropriate type (e.g., Object, Clothing, etc.) for your custom model.
- Click on "Import Mesh" and select your OBJ file. Position and scale your model as needed within the studio's 3D view.
- Import your texture and any additional resources using the appropriate buttons in the studio's interface.
- Customize your model's properties, such as name, description, and category, using the "Properties" panel.
- Click on "Package" to create your custom content package. Choose a save location and give your package a name.
Testing and Installing Your Custom Model
Before sharing or using your custom model in-game, ensure it works correctly:
- Place your packaged file in your Sims 4 Mods folder, typically located at:
- C:\Users\YourUsername\Documents\Electronic Arts\The Sims 4\Mods
- Launch The Sims 4 and test your custom model in-game. Ensure it appears correctly and functions as expected.
- If you encounter issues, use the Sims 4 Studio's "Log" feature to help diagnose and troubleshoot problems.
Troubleshooting Common Issues
Here are some common issues and solutions when adding custom models to The Sims 4:

| Issue | Solution |
