WebGL remote download material problem

Hello. I am new to using addressables and have been working with them for only 2 weeks now. So now I am kinda stuck with my prefabs remote downloading. The problem is that it seems prefabs materials are not downloaded correctly on WebGL build platform. I just made several prefabs of default 3D objects and tried to download them by label using following script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.AddressableAssets;
5. using UnityEngine.ResourceManagement.ResourceLocations;
6. using System;
7. using UnityEngine.ResourceManagement.AsyncOperations;
8.  
9. public class PrefabsDownloader : MonoBehaviour
10. {
11.     [SerializeField]
12.     private string modelsLabel;
13.  
14.     private List<GameObject> instantiatedModels = new List<GameObject>();
15.  
16.     public void SpawnModels()
17.     {
18.         LoadPrefabs(InstantiatePrefabs);
19.     }
20.  
21.     public void LoadPrefabs(Action<AsyncOperationHandle<IList<GameObject>>> onLoaded)
22.     {
23.         Addressables.LoadAssetsAsync<GameObject>(modelsLabel, null).Completed += onLoaded;
24.     }
25.  
26.     public void InstantiatePrefabs(AsyncOperationHandle<IList<GameObject>> prefabsDownloadHandle)
27.     {
28.         if (prefabsDownloadHandle.Status == AsyncOperationStatus.Succeeded)
29.         {
30.             IList<GameObject> prefabs = prefabsDownloadHandle.Result;
31.  
32.             foreach (GameObject prefab in prefabs)
33.             {
34.                 instantiatedModels.Add(Instantiate(prefab));
35.             }
36.         }
37.     }
38.  
39.     void Start()
40.     {
41.         SpawnModels();
42.     }
43. }

The result I got you can find among attached files. This seems to be exclusive for WebGL because on MacOS build platform everything was downloaded correctly.

 

Hello, I am using Unity 2019.3.2f1, addressables - 1.7.5.
