# Create a Prefab Variant based on an existing FBX model Create a Prefab Variant based on an existing FBX Model Prefab without having to perform FBX re-export. For example, you might need to do this if you already exported a Unity GameObject to FBX using the FBX Exporter, or if you imported an external FBX file in your project. ## Results to expect When you perform this action, Unity: * Keeps the FBX file and its corresponding Model Prefab unchanged, and * Creates a new Prefab Variant based on the Model Prefab. ## Create the Prefab Variant To create a Prefab Variant based on an FBX Model Prefab: 1. In the Project window, right-click on the Model Prefab to use as the base of the Prefab Variant. 2. Select **Create** > **Prefab Variant**. ## Further management After you create the Prefab Variant: * The FBX file remains unchanged and continues to be the model source which you can edit via a 3D modeling application. * The created Prefab Variant becomes the only asset you should manipulate and instantiate in your Unity project. ## Additional resources * [FBX files and Prefab Variants](prefab-variants-concepts.md) * [FBX Prefab Variant workflow](prefab-variants-concepts.md) * [Export to FBX](export.md) * [Importing a model](https://docs.unity3d.com/Manual/ImportingModelFiles.html)
