I everybody, I’m making a loading scence using scene manager LoadScenceAsync. I would use the progress value to have an loading UI, but I have always 0. I found anywhere an answer.
Do you know please, how could I do ?

here my code :
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using UnityEngine.SceneManagement;

public class LevelLoader : MonoBehaviour {

	public GameObject LoadingScene;
    public Image LoadingBar;
    public Text textPourcentage; //The text with the percentage increasing
  
    public void LoadLevel (string nomScene) //The name of the scene
	{
        
        StartCoroutine (LevelCoroutine (nomScene));
	}

   
	IEnumerator LevelCoroutine (System.String nomScene)
	{
		LoadingScene.SetActive (true);
        
		AsyncOperation async = SceneManager.LoadSceneAsync(nomScene);
 

        while (!async.isDone) {
            LoadingBar.fillAmount = async.progress ; //Async progress returns always 0 here      
            Debug.Log(async.progress);
            textPourcentage.text = LoadingBar.fillAmount + "%"; //I have always 0% because he fillAmount is always 0
              yield return null;

		}
	}
}

You ever figure this out? The only way I get any time of % is by splitting my scenes up into chunks and loading a list of scenes as additive…
