Lerp RenderSettings skybox

Question

I want to switch my skybox from a day material to a night material for this I use :

 Material night;
 int skyboxflag = 0;
 int flag = 0;
 float t;
 public float smooth = 1;
 
 void Start () {
     night = Resources.LoadAll("Night_mat",typeof(Material))[0] as Material;
 
 }
 
 void Update () {
 if (skyboxflag == 1) {
         if(flag == 0){
             t = Time.time;
             flag = 1;
         }
         RenderSettings.skybox.Lerp(RenderSettings.skybox, night,(Time.time - t)/smooth);
         if(Time.time - t > smooth){
             skyboxflag = 0;
         }
             }
 }
 void OnTriggerEnter(Collider other)
 {
     if (other.gameObject.name == "Avatar") {
         skyboxflag = 1;
 
             }
     }

but nothing happens I keep having the day skybox.

what is the correct way to change the skybox smoothly from a material to another

Thank you

I have the same problem in Unity 5. I was using http://wiki.unity3d.com/index.php?title=SkyboxBlended in Unity 4, but that shader no longer works in Unity 5. Does anyone have an idea how to do skybox blending in Unity 5?

EDIT: Found a fix!

This Skybox Blending shader works in Unity 5. http://answers.unity3d.com/questions/371078/having-a-changing-skybox-depending-on-location-of.html

using UnityEngine; using System.Collections;

public class dayknight : MonoBehaviour {

 public Material mat;
 public Material day;
 public Material skyBox;
   

 float t = 0.02f;
 float a;
 // Use this for initialization
 void Start ()
 {
        RenderSettings.skybox.Lerp(skyBox, mat, 0.5f);  //Here assaying mat matiral as default .
 }
 
 // Update is called once per frame
 void Update ()
 {
         a = (Time.time *4) % 360;

         transform.eulerAngles = new Vector3(transform.rotation.x + a , transform.rotation.y, transform.rotation.z);

       
         if(a > 25 && a < 150 )
         {
            //Changing default to day matiral skybox.
             RenderSettings.skybox.Lerp(skyBox,day,0.5f * Time.deltaTime); 
         }
          
        else if (a > 150 && a < 185)
         {
             //Changing day matiral to mat matiral
             RenderSettings.skybox.Lerp(skyBox,mat,0.5f*Time.deltaTime);
         }
 }

}

Hope that it will help you!!!!!!

@pronobroy Hi! I encounter a problem when using RenderSettings.skybox.Lerp. The link below shows the same problem with $$anonymous$$e. It seems to work only once. http://forum.unity3d.com/threads/rendersettings-skybox-lerp-not-cooperating.287566/ So now I am using Color.Lerp and then set the color to my skybox.

@Tarikm I just made a video about this because a lot of people are saying it's not possible to do in script but it definitely is!

I hope this video is helpful to people!
