Declaration

public static void ImportAsset(string path, ImportAssetOptions options = ImportAssetOptions.Default);

Description

Import asset at path.

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

All paths are relative to the project folder, for example: "Assets/MyTextures/hello.png"

See Also: ImportAssetOptions.
