 Când folosești labels: pentru a grupa conținut (ex: track_winter, ads, skins_pack_01) și a descărca “pachetul”.
+Exemple:
+AssetBundle de pe disc și aplicarea unei texturi
+<code c#>
+using UnityEngine;
+using System.Collections;
+public class LoadTextureFromBundle : MonoBehaviour
+{
+    public string bundlePath;          // ex: Application.persistentDataPath + "/bundles/ads"

+    {
+        var bundleCreateRequest = AssetBundle.LoadFromFileAsync(bundlePath);
+        yield return bundleCreateRequest;
+        var bundle = bundleCreateRequest.assetBundle;
+        if (bundle == null)
+        {
+            Debug.LogError("AssetBundle load failed: " + bundlePath);
+            yield break;
+        }
+        var texRequest = bundle.LoadAssetAsync<Texture2D>(textureAssetName);
+        yield return texRequest;
+        var tex = texRequest.asset as Texture2D;
+        if (tex == null)
+        {
+            Debug.LogError("Texture not found in bundle: " + textureAssetName);
+            bundle.Unload(false);
+            yield break;
+        }
+        // aplică textura
+        ApplyTexture(targetRenderer, tex);
+        // bundle.Unload(false) păstrează asset-urile încărcate în memorie
+        bundle.Unload(false);
+    }
+    private void ApplyTexture(Renderer r, Texture2D tex)
+    {

+AssetBundle din memorie (de ex. după download)
+<code c#>

+Addressables

+using UnityEngine;
+using UnityEngine.AddressableAssets;
+using UnityEngine.ResourceManagement.AsyncOperations;
+using System.Collections;
+using System.Collections.Generic;
+public class AddressablesDlcExample : MonoBehaviour

+Încărcare scenă Addressable (DLC track)
+<code c#>
+using UnityEngine;
+using UnityEngine.AddressableAssets;
+using UnityEngine.SceneManagement;
+using System.Collections;
+public class LoadSceneAddressable : MonoBehaviour

+Pentru gestiunea reclamelor, puteti folosi texturi gestionate/acutalizate din cod:
+<code c#>
+Renderer r = GetComponent<Renderer>();
+Texture2D tex = /* încărcată din URL / bundle / addressables */;
+r.material.mainTexture = tex;
+var r = GetComponent<Renderer>();
+var mat = r.material;
+mat.SetTexture("_BaseMap", tex); // URP Lit
+using UnityEngine.UI;
+Texture2D tex = ...;
+Sprite sp = Sprite.Create(tex, new Rect(0,0,tex.width, tex.height), new Vector2(0.5f,0.5f));
+GetComponent<Image>().sprite = sp;
