AssetPostprocessor.OnAssignMaterialModel(Material,Renderer)

Description

提供源材质。

返回的材质将分配给渲染器。 如果返回 null，Unity 将使用其默认材质查找/生成方法来分配材质。 系统会在导入 sourceMaterial 之前直接从模型中生成 sourceMaterial，并在执行 OnAssignMaterial 之后立即将其销毁。

    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;
    }
}
