IsForeignAsset(Object)
Checks whether an asset object is a foreign asset, created outside Unity.
public static bool IsForeignAsset(Object obj)
Parameters
The asset object to check.
Returns
Type | Description |
|---|---|
| bool | True if the asset is a foreign asset. Otherwise, false. |
Remarks
A foreign asset is an asset that wasn't created in Unity, for example a .png texture file. During import, Unity creates a serialized representation of a foreign asset in the folder of the project. This happens when you first add the asset, when it changes outside Unity, and when you change its import settings. An asset that Unity creates, such as a material, is a native asset. For more information, refer to Native asset importers reference and AssetDatabase.IsNativeAsset.
LibraryExamples
