[XNA] понимание Basiceffect / Графика / Форум / Программирование игр / GameDev.ru

В примерах часто встречается пдобный код

foreach (ModelMesh mesh in newModel.Meshes)
{
        foreach (BasicEffect effect in mesh.Effects)
        {
            textures[i++] = effect.Texture;
        }
}

Возникает вопрос, если BasicEffect это некий типичный Effect, то как именно работает свойсво Texture?
Можно ли получить объект текстуры без приведения к Basiceffect?

По идее так:

   Effect e;
      foreach (EffectParameter p in e.Parameters)
      {
        Texture2D tex = p.GetValueTexture2D();
      }
