Why am I getting "AssetImporter is referencing an asset from the previous import..."?

Hi @Shinkaze33 ,

The error you are seeing is due to an asset having a broken reference to itself. The issue can be fixed by reserializing the problematic assets. In this case it's:

 \Assets\Oculus\SampleFramework\Core\CustomHands\Animations\r_hand_relax_3qtr_fist_anim.fbx

Unfortunately, reserializing can be done only through script, so I've attached a simple script that you can add in your Assets/Editor folder (you can create it if it doesn't exist) and it will add an option to "Force Reserialize" when you right click the assets in the editor.

 using UnityEditor;
 using UnityEngine;
 
 [CreateAssetMenu()]
 public class PrefabReferenceFixer : ScriptableObject
 {
     [MenuItem("Assets/Force Reserialize")]
     private static void ForceReserialize()
     {
         GameObject[] selection = Selection.gameObjects;
         string[] objectPaths = new string[selection.Length];
 
         for(int i = 0; i < selection.Length; ++i)
         {
             objectPaths[i] = AssetDatabase.GetAssetPath(selection[i]);
         }
 
         AssetDatabase.ForceReserializeAssets(objectPaths);
     }
 }

You can either reserialize the specific asset, or the whole Oculus folder. That should get rid of the error for you.

Thanks,
Martin
