AssetDatabase.ExtractAsset

Parameters

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.
