Changing Skybox's texture via code.

Questions & Answers

Hi,

I’ve read about how to change Skybox’s texture via code. I’m interested to change RenderSetting’s one.

I googled a lot and tried whatever I could find, from this:

RenderSettings.skybox.mainTexture = myTexture;

to:

//				RenderSettings.skybox.SetTexture("_FrontTex", textures[kos]);
//				RenderSettings.skybox.SetTexture("_BackTex", textures[kos]);
//				RenderSettings.skybox.SetTexture("_LeftTex", textures[kos]);
//				RenderSettings.skybox.SetTexture("_RightTex", textures[kos]);
//				RenderSettings.skybox.SetTexture("_UpTex", textures[kos]);
//				RenderSettings.skybox.SetTexture("_DownTex", textures[kos]);

to:

Camera.main.GetComponent<Skybox>().material.SetTexture("_FrontTex", textures[kos]);
				Camera.main.GetComponent<Skybox>().material.SetTexture("_BackTex", textures[kos]);
				Camera.main.GetComponent<Skybox>().material.SetTexture("_LeftTex", textures[kos]);
				Camera.main.GetComponent<Skybox>().material.SetTexture("_RightTex", textures[kos]);
				Camera.main.GetComponent<Skybox>().material.SetTexture("_UpTex", textures[kos]);
				Camera.main.GetComponent<Skybox>().material.SetTexture("_DownTex", textures[kos]);

But none of them changed it. What am I missing?

Thanks!

Reworked my solution. This version will allow you to use whatever textures you want. Honestly its a little rough and has some superfluous struct action, but it works, and I’m not going to spend any more time on it. :slight_smile:

using UnityEngine;
using System.Collections;

public class SkyboxSetter : MonoBehaviour
{    
	public static Material CreateSkyboxMaterial(SkyboxManifest manifest)
	{
		Material result = new Material(Shader.Find("RenderFX/Skybox"));
		result.SetTexture("_FrontTex", manifest.textures[0]);
		result.SetTexture("_BackTex", manifest.textures[1]);
		result.SetTexture("_LeftTex", manifest.textures[2]);
		result.SetTexture("_RightTex", manifest.textures[3]);
		result.SetTexture("_UpTex", manifest.textures[4]);
		result.SetTexture("_DownTex", manifest.textures[5]);
		return result;
	}

	public Texture2D[] textures;

	void OnEnable()
	{
		SkyboxManifest manifest = new SkyboxManifest(textures[0], textures[1], textures[2], textures[3], textures[4], textures[5]);
		Material material = CreateSkyboxMaterial(manifest);
		SetSkybox(material);
		enabled = false;
	}

	void SetSkybox(Material material)
	{
		GameObject camera = Camera.main.gameObject;
		Skybox skybox = camera.GetComponent<Skybox>();
		if (skybox == null)
			skybox = camera.AddComponent<Skybox>();
		skybox.material = material;
	}
}

public struct SkyboxManifest
{
	public Texture2D[] textures;

	public SkyboxManifest(Texture2D front, Texture2D back, Texture2D left, Texture2D right, Texture2D up, Texture2D down)
	{
		textures = new Texture2D[6]
		{
			front,
			back,
			left,
			right,
			up,
			down
		};
	}
}

The link below from the unity wiki may help you.

It blends 2 sky boxes. You just need it to blend them real fast from your 1st skybox to the one you want to replace it with.

Hope it helps.
