AssetPostprocessor.OnAssignMaterialModel(Material,Renderer)

설명

Feeds a source material.

The returned material will be assigned to the renderer. If you return null, Unity will use its default material finding / generation method to assign a material. The sourceMaterial is generated directly from the model before importing and will be destroyed immediately after OnAssignMaterial.

    class MyMeshPostprocessor extends AssetPostprocessor {

    function OnAssignMaterialModel (material : Material, renderer : Renderer) : Material {
        var materialPath = "Assets/" + material.name + ".mat";

        // Find if there is a material at the material path
        // Turn this off to always regeneration materials
        if (AssetDatabase.LoadAssetAtPath(materialPath, typeof(Material)))
            return AssetDatabase.LoadAssetAtPath(materialPath, typeof(Material));
        
        // Create a new material asset using the specular shader
        // but otherwise the default values from the model
        material.shader = Shader.Find("Specular");
        AssetDatabase.CreateAsset(material, "Assets/" + material.name + ".mat");
        return material;
    }
}
