ScriptedImporter

Description

Abstract base class for custom Asset importers.

Scripted importers are scripts that are associated with specific file extensions. They are invoked by Unity's Asset pipeline to convert the contents of associated files into Assets.

Use the ScriptedImporterAttribute class to register custom importers with the Asset pipeline.
