Asset bundles showing pink using new URP

I have 2 projects and upgraded them to Unity 2020.1.13 using AR Foundation 4.0.9, AR Core 4.0.9, and Universal RP 8.2.0

Then i just change the settings on both projects to use the new Universal RP using this tutorial

On one project i just create asset bundles to upload them to my server, the other is an AR Core app that downloads them and puts them on scene, but now all my asset bundles are pink

I upgraded the materials on the first project, rebuild the Asset Bundle and upload it to the server, it stills shows it pink

My asset instantiator on the App is pretty straightfoward:

Code (CSharp):

1. using (UnityWebRequest ww2 = UnityWebRequestAssetBundle.GetAssetBundle(asset["file_android"], (uint)asset["version"], 0))
2.     {
3.         operation = ww2.SendWebRequest();
4.  
5.         while (!operation.isDone)
6.         {
7.             yield return null;
8.         }
9.  
10.         if (ww2.isNetworkError || ww2.isHttpError)
11.         {
12.             Debug.Log(ww2.error);
13.             Debug.Log(asset["url"]);
14.         }
15.         else
16.         {
17.             // Get downloaded asset bundle
18.             AssetBundle bundle = DownloadHandlerAssetBundle.GetContent(ww2);
19.             Material[] materials = bundle.LoadAllAssets<Material>();
20.             GameObject[] objects = bundle.LoadAllAssets<GameObject>();
21.             // Sprite[] sprites = bundle.LoadAllAssets<Sprite>();
22.             bundle.Unload(false);
23.  
24.             GameObject newObj = Instantiate(objects[0], transform);
25.             newObj.transform.localScale = new Vector3(scaleFactor, scaleFactor, scaleFactor);
26.         }
27.     }
28.  

And my Asset Bundle Creator is just extracted from the manual:

Code (CSharp):

1. string folderName = "AssetBundles";
2.     string filePath = Path.Combine(Application.streamingAssetsPath, folderName);
3.     AssetBundleManifest asset = BuildPipeline.BuildAssetBundles(filePath, BuildAssetBundleOptions.None, BuildTarget.Android);
4.  
5.     AssetDatabase.Refresh();
6.     string oldfn = filePath + "/" + asset.GetAllAssetBundles()[0];
7.     string newfn = filePath + "/" + asset.GetAllAssetBundles()[0] + ".asset";
8.     System.IO.File.Move(oldfn, newfn);
9.     Debug.Log("Archivo Creado:" + newfn);
10.     EditorUtility.RevealInFinder(newfn);
11.  

Any ideas on what can be happening?

 

Having the same problem myself, unable to resolve it at the moment.

 

I had the same problem before and the only solution I'd found was to add the shader into the "Aways included shaders" in the project settings.
