Unity3D: Change skybox color via script?

Question

I am working on a game in the engine Unity, and am trying to make the skybox change color based on the time of day, but I can't seem to find out how to get it working.. What I want to do, I think, is to change the color of the material I use for the skybox in render settings, and be able to set it using one variable for red, one for green and one for blue.

I am using C#.

Thanks in advance for all answers :)

From the code you displayed in the comment:

RenderSettings.skybox.SetColor("_Tint", 0, 0, blue)

I think you mean

RenderSettings.skybox.SetColor("_Tint", Color.blue)

no need for extra zeros and remember that the color "blue" is a member variable of the Color class.

Next you would have to develop a time system and based on the time var you pass to the script controlling the skybox renderer you would then use a Lerp function to smoothly transition from one color to the next... like this

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
    public Color colorStart = Color.blue;
    public Color colorEnd = Color.green;
    public float duration = 1.0F;
    void Update() {
        float lerp = Mathf.PingPong(Time.time, duration) / duration;
        RenderSettings.skybox.SetColor("_Tint", Color.Lerp(colorStart, colorEnd, lerp));
    }
}

Then you could write a function to change the colorStart and colorEnd...

Hope this helps...

We can change Skybox color using the _Tint property. RenderSettings is the base class used to change the render properties at run time. For ensuring the attribute is existing in the skybox is done by the HasProperty(). SetColor() is used to set the color of the skybox.

     if (RenderSettings.skybox.HasProperty("_Tint"))
         RenderSettings.skybox.SetColor("_Tint", Color.red);
     else if (RenderSettings.skybox.HasProperty("_SkyTint"))
         RenderSettings.skybox.SetColor("_SkyTint", Color.red);

you can make your own skybox too in unity by changing texture shape into a cube one then apply for those changes it will create a cube mesh which you can simply drop it into your unity editor scree.

and if you want to load multiple skybox materials on run time by click on button I have that code for that i hope it will help you for building a project in which you want to change skybox by some time or by using other input method.

enter code here

public class skybox : MonoBehaviour {

enter code here
public Material[] secondSkybox;
public static int i = 0;
public void skyboxOn()
{

    if (i == 0) {
        RenderSettings.skybox = secondSkybox[0];
        i++;
    }
    else if(i==1)
    {
        RenderSettings.skybox = secondSkybox[1];
        i++;
    }else if(i==2)
    {
        RenderSettings.skybox = secondSkybox[2];
        i=0;
    }
    }
}
