AssetDatabase.IsNativeAsset

Parameters

Returns

bool True if the asset is a native asset, otherwise false.

Description

Determines whether the asset is a native asset.

A native asset is a file produced directly by Unity's serialization system (for example, a .mat material file is a native asset)

Scenes, prefabs and assembly definitions aren't native assets. For more information, refer to Supported asset types.
