Very nice attempts from both of you to obtain either small 3D models or very nice renderings with a row of bottles
For your information, you should know that the Ni factor in MTL files is used as the optical density (see MTL specs here). If glass has an optical density of 1.5 like Cec used it, other materials have often a different value like water which optical density is 1.333. It would be interesting to test that if some of you have the patience.
