public static string ExtractAsset(Object asset, string newPath);

Parameters

asset The sub-asset to extract.
newPath The file path of the new Asset.

Returns

string An empty string if Unity has successfully extracted the Asset, or an error message if not.

Description

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.
