# Import/Export: MLMask and MLSetup

## MultilayerMask

You can export and import MultilayerMasks via Wolvenkit.

{% endhint %}

### Exporting MLMASK files

Mask files can be exported with the Import/Export tool in a similar fashion to [texture files](/wolvenkit/wolvenkit-app/usage/import-export/textures.md). Additionally, WolvenKit will automatically create a custom `masklist` file, which can be used for importing modified mlmask files.

{% hint style="info" %}
Masklist files can be opened and modified with any text-editing program.

You can use absolute or relative texture paths.
{% endhint %}

### Importing MLMASK files

Use the **import** tool to select any `masklist` file within the *raw directory* of the Project Explorer. If you don't have one, export an MLMask first.

## MultilayerSetup

You can export and import MLSetup files via JSON and edit them with the MLSetupBuilder.
