about load asset by code.

hello, everybody.

i'm comfuse about the asset load API.

i want generate *.prefab file when import the *.fbx file.

• step 1: load *.fbx file
• step 2: Create *.prefab file
• step 3: load *.prefab file and Instantiate it.

i try the code such below, but return null: [Windows]

Code (CSharp):

1.  
2.               var prefab = AssetDatabase.LoadMainAssetAtPath("");
3.                 Debug.Log(prefab);
4.                 // This instantiates the prefab into the Hierarchy.
5.                 var instance = (GameObject)PrefabUtility.InstantiatePrefab(prefab);
6.  

 

i try it, but fail again.

so, I think this is bug of Unity 4.6 version.
