Cannot load animation clip from asset bundle!!! :( How to set animation clip to legacy in code?

So, I packed a model, a animation clip of it and material into asset bundle with the following code:

Code (CSharp):

1. public static void buildAllAssetBundles()
2.     {
3.         System.Guid fileGUID = System.Guid.NewGuid();
4.  
5.         AssetBundleBuild[] buildInfo = new[]
6.         {
7.             new AssetBundleBuild {assetBundleName=fileGUID.ToString()+".unity3d", assetNames=new[]{"Assets/ARAsset"}}
8.         };
9.        
10.         string projectPath = Directory.GetParent (Application.dataPath).FullName;
11.  
12.         string outputPathWeb = projectPath + "/assetbundle/";
13.  
14.         Directory.CreateDirectory (outputPathWeb);
15.  
16.         EditorUserBuildSettings.SwitchActiveBuildTarget (BuildTarget.WebGL);
17.         BuildPipeline.BuildAssetBundles (outputPathWeb, buildInfo,BuildAssetBundleOptions.CompleteAssets |  BuildAssetBundleOptions.CollectDependencies, BuildTarget.WebGL);
18.         System.IO.File.Move(outputPathWeb + "/" + fileGUID.ToString()+".unity3d", outputPathWeb + "/" + "asset.unity3d");
19.         System.IO.File.Move(outputPathWeb + "/" + fileGUID.ToString()+".unity3d.manifest", outputPathWeb + "/" + "asset.unity3d.manifest");
20.         Debug.Log ("AssetProcess: Assetbundle for Web created");
21.  
22.     }

Then, I load the model and the animation with the following code:

Code (CSharp):

1.     IEnumerator download(string inUrl)
2.     {
3.         while (!Caching.ready)
4.             yield return null;
5.        
6.         var www = new WWW(inUrl);
7.         yield return www;
8.         if (!string.IsNullOrEmpty(www.error))
9.         {
10.             Debug.Log(www.error);
11.         }
12.         var myLoadedAssetBundle = www.assetBundle;
13.  
14.         var prefab = myLoadedAssetBundle.LoadAsset<GameObject>("01_Idel");
15.         currentObj = Instantiate (prefab);
16.         currentObj.transform.position = new Vector3 (0, -0.5f, 0);
17.  
18.         AnimationClip animationClip = myLoadedAssetBundle.LoadAsset<AnimationClip> ("Take002);
19.        animationClip.legacy = true;
20.  
21.        currentObj.GetComponent<Animation> ().AddClip(animationClip,animationClip.name);
22.      
23.        currentObj.GetComponent<Animation> ().Play ("Take002");
24.  
25.    }

But the animation clip is empty!!!


If I set the .anim file to legacy manually in debug mode first then export the asset bundle, the animation will works fine.


The thing is, I have thousands of hundreds of those clip I need to pack, it's not possible to set it to legacy manually I wonder is there anyway to set it in code?
I try to do it with AssetPostprocessor with no success:

Code (CSharp):

1. private void OnPreprocessAnimation()
2.     {
3.         Debug.Log ("AssetProcess: Importing animation");
4.         Debug.Log ("dllm");
5.  
6.         var modelImporter = assetImporter as ModelImporter;
7.         modelImporter.clipAnimations = modelImporter.defaultClipAnimations;
8.         foreach(ModelImporterClipAnimation anim in modelImporter.clipAnimations){
9.             anim.wrapMode = WrapMode.Loop;
10.         }
11.     }

There is not any parameter for me to set the animation type.

Please Help!!! I'm stuck for a week now!!!

 

Did you manage to solve this problem? I'm stuck in this too.

 

F***, I'm stuck in this too too.

 

I have this problem too, is there any solution?

 

For who came from google, fixed doing this:

Code (CSharp):

1.  
2. string url = "http://downloadurl/animation.prefab";
3.  
4. using (UnityWebRequest www = UnityWebRequestAssetBundle.GetAssetBundle(url))
5. {
6.     yield return www.SendWebRequest();
7.  
8.     if (www.result == UnityWebRequest.Result.Success)
9.     {
10.         AssetBundle bundle = DownloadHandlerAssetBundle.GetContent(www);
11.         AssetBundleRequest assetBR = bundle.LoadAssetAsync<AnimationClip>("/Assets/Animation.anim");
12.         AnimationClip anim = assetBR.asset as AnimationClip;
13.  
14.         Debug.Log(anim);
15.     }
16.     else
17.     {
18.         Debug.Log("Download Failed");
19.     }
20. }
21.
