# LookFileOverrideEnable

LookFileOverrideEnable allows you to bring into the scene materials from a specific Look File/pass so you can override them before the Look File is resolved using the LookFileResolve node.

Connection Type | Connection Name | Function
Input | in | The place in the node graph where you want to bring into set up an override on a look file or pass before it's resolved.

Control (UI) | Default Value | Function
lookfile | N/A | Selects the Look File to import materials from. For more information, refer to the Asset and File Path Widget Types in the Common Parameter Widgets.
versionsToOverride | Only this Version | Specifies on which version of the Look File the overrides are reflected.
locationForMaterials | Use asset name | Sets where to import the materials in the scene graph. • Use asset name - the materials are imported in a unique location based on the lookfile asset fields. • User-specified - provides a parameter, userLocation, for you to specify a namespace for the materials.
When locationForMaterials: User-specified
userLocation | N/A | Specifies a namespace for the materials. For instance, a material at /root/materials/geo/chrome with userLocation default_pass is placed at /root/materials/default_pass/geo/chrome.
