I forgot to show you last week that the spritebatch draw code need to be modified slightly in order top mix 2D and 3D You need to use SaveStateMode.SaveSate is you don't explicitly order everything in you DrawCode. Saving states can be SLOOWWWWW and significantly reduce your performance

spriteBatch.Begin(SpriteBlendMode.AlphaBlend, SpriteSortMode.Deferred, SaveStateMode.SaveState);
