Unity supports many asset file types via its collection of built-in importers. Most of these importers are implemented in the Unity Editor’s native code, and are named “native importers”. They provide the import functionality for most of Unity’s basic asset types, such as 3D models, Textures, and audio files.

Scripted importers allow you to write your own custom importers for formats that Unity does not natively support. However, in addition to the built-in native importers listed above, some of Unity’s own built-in importers are themselves implemented as scripted importers. This is because they are implemented in C# in core packages, rather than within the Editor’s native code itself. Unity imports scripted importer assets after native importer assets.
