public static bool CopyAsset(string path, string newPath);


path Filesystem path of the source asset.
newPath Filesystem path of the new asset to create.


bool Returns true if the copy operation is successful or false if part of the process fails.


Duplicates the asset at path and stores it at newPath.

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

using UnityEngine;
using UnityEditor;

public class AssetDatabaseExamples : MonoBehaviour { [MenuItem("AssetDatabase/Duplicate Material")] static void DuplicateMaterial() { const string assetPath = "Assets/Materials/CarMaterial.mat"; for (var i = 0; i < 20; i++) { if(!AssetDatabase.CopyAsset(assetPath, $"Assets/Duplicates/Materials/CarMaterial{i}.mat")) Debug.LogWarning($"Failed to copy {assetPath}"); } } }

Any errors and warnings from the copy operation are reported in the log and the console.
