Changing a material during runtime only adds the Default Material

Graphics Shaders & Materials

I’m having a problem in Unity 5.5.f1 where if I change a material during run time it does NOT add the material that I want. I have a reference to a prefab material, and when I change the material to that, then it just adds the ‘Default Material’ instead. The material works fine in the editor, and the shader is not broken either.

Here is how I am changing the material in my code:

public Material outlineMat;  // The material that I want to change to
if(/* im looking at this  */)
{
     computerMeshRend.materials[1] = outlineMat;
}
// Otherwise put it to null
else
{
      computerMeshRend.materials[1] = null;
}

I can’t pick out why this is happening… Possibly has something to do with the material being a prefab?

I don’t think you can modify individual elements of the .materials[ ] array using the .materials property of a Renderer.

You need to instead make a copy of the material array, modify the copy, then assign the copy back to the .materials property all at once.
