Load Material to GameObject

Questions & Answers

Hi there,

I'm trying to load a material that has a Bumpmap added to it. If it can't find the material for the object, then it'll look for just a basic Texture2D texture.

 try
        {
            sphere.renderer.material = Resources.Load("Planets/" + PlanetType.ToString()+".mat") as Material;
            if (sphere.renderer.material == null) throw new Exception();
        }
        catch (Exception)
        {
            sphere.renderer.material.mainTexture = Resources.Load("Planets/"+PlanetType.ToString()) as Texture2D;
        }

        if (Texture != null)
        {
            sphere.renderer.material.mainTexture = Texture;
        }

Now it's not working. It's just loading an empty material in there. I rechecked the material to make sure that I didn't save it incorrectly. But it shows that the textures are still there. I checked the Material property to make sure it not read only. but it isn't..

So what am I doing wrong here?? If this will not work, how would I go about doing this.

Files are :

  • Acura.png = texture
  • Acure_BM.png = bumpmap
  • Acure.mat = material (including all bumpmap and information)

Thanks

The material load is wrong for sure - you can't add .mat on the end of it. If you have two items with the same name but different types, use the overload of Resources.Load which takes a second parameter for the type.

On top of that, you're currently assigning a null material to the renderer, throwing an exception, then using the null material as if nothing happened.

If it were me, I'd do something more like this:

Material mat = Resources.Load("Planets/" + PlanetType.ToString(), typeof(Material)) as Material;
if (mat != null)
{
    sphere.renderer.material = mat;
    Texture2D tex = Resources.Load("Planets/" + PlanetType.ToString(), typeof(Texture2D)) as Texture2D;

    if (tex != null)
        sphere.renderer.material.mainTexture = tex;
}
else if (Texture != null)
        sphere.renderer.material.mainTexture = Texture;

try
{
Material mat = Resources.Load(“Planets/” + PlanetType.ToString(), typeof(Material)) as Material;
if (mat != null)
{
sphere.renderer.material = mat;
}
else // mat is null, load the texture
{
Texture2D tex = Resources.Load(“Planets/” + PlanetType.ToString(), typeof(Texture2D)) as Texture2D;

     if (tex != null)
        sphere.renderer.material.mainTexture = tex;
  }

}
catch (Exception)
{
   sphere.renderer.material.mainTexture = Resources.Load("Planets/" + PlanetType.ToString(), typeof(Texture2D)) as Texture2D;
}
