| asset | The sub-asset to extract. |
| newPath | The file path of the new Asset. |
string An empty string if Unity has successfully extracted the Asset, or an error message if not.
Creates an external Asset from an object (such as a Material) by extracting it from within an imported asset (such as an FBX file).
NOTE: The feature is currently only available for materials embedded in model assets.
All file paths are relative to the project folder. For example: "Assets/Materials/myMaterial.mat".
Method throws ArgumentNullException when the Asset is null and ArgumentException when the file path is null or empty.
