Changing MATERIALS in runtime

I wanna change ALL materials from a given renderer in runtime, but it seems that assigning a value to the materials array does not work. I made a simple example to show this:

Code (csharp):

1.  
2. using UnityEngine;
3. class DummyMaterial:MonoBehaviour
4. {
5.     public Material otherMaterial;
6.     void Start()
7.     {
8.         Renderer[] renderers = GetComponentsInChildren<Renderer>();
9.         foreach (Renderer r in renderers)
10.         {
11.             for (int i = 0; i < r.materials.Length; i++)
12.             {
13.                 r.materials[i] = otherMaterial;
14.             }
15.         }
16.     }
17. }
18.  
19.  

If I change the 'material' property, it works, but my meshes have more than one material.

What is the right way to change a material?
Thanks

 

Just got it...you have to swap the WHOLE array, not every single element

Code (csharp):

1.  
2. Material[] newMaterials = new Material[renderer.sharedMaterials.Length];
3. ...
4. //do something
5. ...
6. renderer.materials = newMaterials;
7.  

See ya

 

bah, good work.
I've been trying on and off all last weekend trying to resolve exactly that same problem.

I do find that solution kind of counter intuitive/productive, would be nice to be able to just change 1 material... but i digress...


thanks again!

 

Thank you so much! I was getting crazy with this issue today. You saved my day!

 

Hey guys!

I am newbie to unity please help me out form this, i am trying to make a unlimited 2d runner game and i have 5 environments to swap as per the user selection, on the play button event i am calling the "SetTheBackground()" method out of 9 bgs only one got effected. (may be the problem is in single frame it has been called). if i kept the folowwing code in update method it's working but fps issue.

we should not call in every frame. please help me out.

using UnityEngine; using System.Collections;

public class BackgroundManager : MonoBehaviour { public static BackgroundManager instance;

1. GameObject mgameObject;
2. publicMaterial[] bgmaterial;
3. voidAwake()
4. {
5. mgameObject =this.gameObject;
6. instance =this;
7. }
8. publicvoidSetTheBackground()
9. {
10. if(GameController.instance !=null){
11. switch(GameController.instance._ThemeType){
12. case eTheme.Theme1:
13. mgameObject.renderer.material= bgmaterial [0];
14. break;
15. case eTheme.Theme2:
16. mgameObject.renderer.material = bgmaterial [1];
17. break;
18. case eTheme.Theme3:
19. mgameObject.renderer.material = bgmaterial [2];
20. break;
21. case eTheme.Theme4:
22. mgameObject.renderer.material = bgmaterial [3];
23. break;
24. case eTheme.Theme5:
25. mgameObject.renderer.material = bgmaterial [4];
26. break;
27. default:
28. break;
29. }
30. }
31. else{
32. }
33. }

Thanks in advance!
