+    "text": "Another important group of materials is those that are somehow glossy. They give a certain clarity to the objects in our scene. A good example is a battery. I'll switch to the camera view a bit from above so we can see the battery better. And I'll say a little about the material that was used here. We have a material called Mosaic. This is a slightly metallic material. very simple in its structure. As we can see in the node, the principal BSTF is defined the color of copper. It is defined that the material is a metal, meaning the metallic value is set to 1 and the roughness value is set to 0.1, so it is quite glossy material. We can also see in the reflections, for example, in the thumbnail, and we can notice in this reflection that anisotropy is used here, which is exactly the technique we used for our kitchen overlay. When it comes to this anisotropy, we can expand the specular here and see that it is set to a value of 1. We can twist it down to 0, and then it will be smaller, but a value of 1 makes the reflections more interesting, so I'll leave it like this. Generally, metal materials in their form are very simple in structure. Here, we can play with reflections using an isotropy or different textures. Roughness, when it comes to color, there's not much philosophy to it. Another example of such a material that I would like to discuss is glass material. I think this piece illustrates it quite well for me. When it comes to glass in blender, especially in cycles, it's quite a problematic material. It's problematic because it's hard to achieve a nice reflection of the glass when it comes to visualization. There are indeed certain specific materials and nodes that directly aim to imitate this, like the node called Glass-Bisne. However, in my personal opinion, it behaves rather mediocre, I would say, indeed. Compared to the denoiser that we currently use, various strange and unusual artifacts appear that do not quite work for my perception and understanding of the visualization. In the case of glass, I generally make my own glass. A bit my own way. This is not entirely true. A correct way of doing it, I would say it's more of a textbook method, but it works well and gives really good results. Here we see an example of such glass and how it is made. And it is made using the principal BSDF node. In this case, we have the base color connected, a white color, and a turquoise color. With the factor set to 0.25, this means that the white color will be used invisible. At 75%, color B, which is the turquoise color, will only be visible at 25%. Thanks to this, we get such subtle reflections of blue color, but our glass isn't fully blue, as it would be if the factor were set to 1. So we can set the value to 0.25 or even lower, like 0.20, it's going to look really cool. When it comes to the construction of my glass, I define it as a metallic object, completely shiny, which bounces in the middle, although I can give a value here bounce at 1, and it will reflect even more, but I think a value of 0.5 will be just fine here. When it comes to transmission, I set the weight value to 1. And the option, the most important one that I juggle is the Alpha option. Alpha, which is what I mentioned earlier, is the setting that determines whether the object is transparent or not. If we have Alpha set to 1, then the object is completely metallic as we defined it and behaves like a mirror. And the lower the Alpha, the more transparent our glass becomes. But it still generates nice reflections. Thanks to this, we can see what's behind our glass material. But we also see some really nice reflections. Like here we can see the reflections of the lamps in our scene, reflections of the window here. And at this moment there's no view outside the window so you can't see anything. Or at least the window frames that are modeled. Glass may, this way looks really nice in scenes and gives really good results. It also doesn't cause artifacts that arise from using denoising, which unfortunately often occur. On the glass material, of course, we can replace the roughness with some texture that we will generate. Different reflections, unlike pure glass, without any smudges, without any imperfections, etc. Nevertheless, at this moment and in this scene I leave the glass without any reflections as pure glass because I believe it looks best in most cases. In the next lesson we'll analyze the materials of the models we've imported. If necessary, we'll make the appropriate adjustments.",
