Description

AssetBundles let you stream additional assets via the UnityWebRequest class and instantiate them at runtime. AssetBundles are created via BuildPipeline.BuildAssetBundle.

Note that bundles are not compatible between platforms. A bundle built for any of the standalone platforms can only be loaded on that platform but not others. Further example, a bundle built for iOS is not compatible with Android and vice versa. One difference is shaders which are different between devices, as are textures.

        yield uwr.SendWebRequest(); // Get the designated main asset and instantiate it.
        Instantiate(Networking.DownloadHandlerAssetBundle.GetContent(uwr).mainAsset);
    }
