Application.LoadLevel with FadeOut

I'm testing some 3D GUIs with a oculus rift rig. And I was looking for a fadein/out script for the cameras. I found one script: Fade-in works great, but Fadeout doesn't work. I'm using triggers to load a new level. In this case the screen freezes and just loads the new level. Is there a way to use fade in general for all triggers / levels? Here's the Screen-Fader script (it uses 2 boxes to block both camera-vision):

 using UnityEngine;
 using System.Collections;
 
 public class Screenfader_level0 : MonoBehaviour {
     
         public float fadeSpeed = 1.5f;          // Speed that the screen fades to and from black.
         
         
         private bool sceneStarting = true;      // Whether or not the scene is still fading in.
         
         
         void Awake ()
         {
             // Set the texture so that it is the the size of the screen and covers it.
             guiTexture.pixelInset = new Rect(0f, 0f, Screen.width, Screen.height);
         }
         
         
         void Update ()
         {
             // If the scene is starting...
             if(sceneStarting)
                 // ... call the StartScene function.
                 StartScene();
         }
         
         
         void FadeToClear ()
         {
             // Lerp the colour of the texture between itself and transparent.
             guiTexture.color = Color.Lerp(guiTexture.color, Color.clear, fadeSpeed * Time.deltaTime);
         }
         
         
         void FadeToBlack ()
         {
             // Lerp the colour of the texture between itself and black.
             guiTexture.color = Color.Lerp(guiTexture.color, Color.black, fadeSpeed * Time.deltaTime);
         }
         
         
         void StartScene ()
         {
             // Fade the texture to clear.
             FadeToClear();
             
             // If the texture is almost clear...
             if(guiTexture.color.a <= 0.05f)
             {
                 // ... set the colour to clear and disable the GUITexture.
                 guiTexture.color = Color.clear;
                 guiTexture.enabled = false;
                 
                 // The scene is no longer starting.
                 sceneStarting = false;
             }
         }
         
         
         public void EndScene ()
         {
             // Make sure the texture is enabled.
             guiTexture.enabled = true;
             
             // Start fading towards black.
             FadeToBlack();
             
             // If the screen is almost black...
             if(guiTexture.color.a >= 0.95f)
                 // ... reload the level.
                 Application.LoadLevel();
         }
     }
