Material Resource will not load when Resources.Load is called

Questions & Answers

Hi,

I am trying to generate meshes to resemble planets using Primitive Spheres. However I am trying to load in a material that I have called barren_01.png using the material barren_01_planet. I have placed these files into a folder named Resources but when the game loads the texture that appears is pure purple (which I assume means the texture was not found). Upon debegging I found that the code where I set the material remains unchanged when using the Resources.Load call.

Why is this happening, what step am I missing?

public class Planet {

private const int MIN_PLANET_RADIUS = 10;
private const int MAX_PLANET_RADIUS = 100;

private PlanetType planetType;
public string Name { get; set; }
private int radius;

public GameObject planetModel;

/// <summary>
/// Generates the planet.
/// </summary>
public void GeneratePlanet()
{
	planetType = (PlanetType)Random.Range(0, System.Enum.GetNames(typeof(PlanetType)).Length);
	radius = Random.Range(MIN_PLANET_RADIUS, MAX_PLANET_RADIUS);
	
	GeneratePlanetModel();
	
	Debug.Log(planetType.ToString() + " Planet Generated");
}

private void GeneratePlanetModel()
{
	planetModel = GameObject.CreatePrimitive(PrimitiveType.Sphere);
	planetModel.transform.localScale *= radius;
	
	TexturePlanetModel();
}

/// <summary>
/// Textures the planet based on its type
/// </summary>
private void TexturePlanetModel()
{
	switch (planetType)
	{
	case PlanetType.Barren:
		planetModel.renderer.material = Resources.Load("barren_01_planet") as Material;
		break;
		
	case PlanetType.Earth:
		planetModel.renderer.material = Resources.Load("barren_01_planet") as Material;
		break;
		
	case PlanetType.Frozen:
		planetModel.renderer.material = Resources.Load("barren_01_planet") as Material;
		break;
		
	case PlanetType.Molten:
		planetModel.renderer.material = Resources.Load("barren_01_planet") as Material;
		break;
		
	case PlanetType.Gas:
		planetModel.renderer.material = Resources.Load("barren_01_planet") as Material;
		break;
		
	case PlanetType.Moon:
		planetModel.renderer.material = Resources.Load("barren_01_planet") as Material;
		break;
	}
}
}

Since I use a multi-level folder structure for textures all I needed was to do the following:

case PlanetType.Barren:
		planetModel.renderer.material.mainTexture = Resources.Load("Textures/barren_01") as Texture;
		break;

I think the actual solution is using:

Resources.Load("material", typeof(Material)) as Material.

The key being “typeof”.
