Resources Load array

I'm using this part of a script to create a texture array loading with Resources.Load, but don't load the image on first position (scena_3_0) with index equal to zero. I check the script several time, but nothing. The script load all the texture except the first (i=0).

 ... function Awake () {
                 
             GroupTexture = new Texture [ArraySize];
             
             for(i = 0; i < GroupTexture.Length; i++){
                 GroupTexture[i]= Resources.Load(TextName + Manager.SceneNumber.ToString() + "_" + i.ToString(), Texture);
                 }
                 
             this.renderer.material.SetTexture("_MainTexture1", GroupTexture[0]);
             this.renderer.material.SetTexture("_MainTexture2", GroupTexture[1]);
             this.renderer.material.SetFloat("_Blend", blend);
         }
         ...
