Prefab loses its materials after running the game - Why?
In my Resources folder I have a prefab. That prefab has a few sub-meshes to which I want to apply a material/texture. So I assign a material by clicking the little black triangle next to "Element 0" in the Materials list & choosing a material. Then I save, and hit the play button
and test my game. Everything is fine. But when I return to the project view in Unity, my meshes no longer have a material. Element 0 says, "Missing (Material)". If I run the game again at this point, those objects have no materials or textures.
The result is I have to re-apply the materials every time I run the game. Can someone tell me what I have to do to make those materials permanent, so they don't get removed when I test the game?

Before: 
After: 
Note: I have a script that changes the texture on these meshes during the game. The code that changes the texture is:
myObject.renderer.material.mainTexture = www.texture;
where "www" is a WWW object.
However, I wouldn't expect that to affect the project files or settings. Am I missing something?
You should only change instances of prefabs, not prefabs themselves. I would generally recommend not using Resources.Load unless you really have to, because you're more likely to make mistakes like that. Typically you do something like this:
var go : GameObject;
function Start () { var instance = Instantiate(go); instance.renderer.material.mainTexture = whatever; }
So you're saying that it is in fact the script that is causing the material to disappear from the prefab?
If I need to dynamically create instances of the prefab at runtime, what better alternative is there to Resources.Load?
@duggulous: yes, it's the script. I edited my answer with some code.
yep, changing the script fixes it. In your example I'm still not sure how to assign "go" to the prefab without using Resources.Load though...
