AssetDatabase.ImportAsset

説明

パスからアセットをインポートします

This imports an Asset at the specified path, and triggers a number of callbacks including AssetModificationProcessor.OnWillSaveAssets and AssetPostProcessor.OnPostProcessAllAssets

すべてのパスは、例えば "Assets/MyTextures/hello.png" のような Project フォルダーに対する相対パスです。
