What you need is a plush material . In essence it is the same plush velvet , only with a longer nap.
If you have carefully studied the pictures plush, or better look at the real stuff live, then you will see that it is a matter of fact, it's shiny hairs sticking out of cotton fabric.
Another striking feature plush is that the hairs in it are relatively rare and chaotic jammed.
In addition, different angles hairs reflect differently, more accurately reflect the different sides of the environment. By this it appears that laid in the same direction the hairs reflect, for example, a bright light source, and the other, darker part of the room. It turns out that plush, as it consists of reflective and non-reflective areas.
That is in fact the reflection depends on the routing of his hairs as they jammed.
It is this the effect of you and watch the pictures on the reference of your chair, where the shadows are deep and do not reflect the reflected light areas at the same time strong enough.
How to physically correct such material?
everything is simple, - to make such a brilliant pile and put it as well as on the pictures😁Naprimer using 3ds max Hair and Fur .
But, of course, the" weight "of the geometry of the chair will be ten times greater than the weight of the scene in which it will be is. The number of polygons is simply terrifying.
It is clear that on such a physical correctness of such a price can be no question.
In this case, the only way, is to use an appropriate texture, simply imitating a pile .
For example, this: In addition, the same texture should be put on reflection, to plush material I began to reflect. Only it should be slightly opdognat so that dark portions become very dark. This prevents reflections in the dark ( "shadow") zones plush material😉
In the reference photo of reflection, as I said, depends on the angle of view on the pile, which at different angles reflects different parts of the environment. That is literally every hair from different angles reflects different objects of the scene. . Like any other reflecting object
"angle of incidence equals the angle of reflection» 😁
it is the same as we discussed in the discussion of anisotropic material steel . Only when the reflective surface portions are not hairs, but simply a micro-grooves on the cutter, as arranged at different angles to the observer in different ways reflecting their environment.
Tk. pile plush is not flat, and laid randomly, that is, the hairs in different zones are inclined at different angles, different areas, actually composed of these hairs reflect differently.
Returning to our material plush, the you can put on difuz maroon color. That is, do all the "hairs" of the same color and only reflections leave our texture.
By the way, I'm not in vain said that reflekshen need to put the same texture, but a bit to fit the dark color. P >
desaturate the texture - you did not is true. Reflection must also be light burgundy instead of white. This is important!
With regard to fizkorrektnosti, we can make a material reflect differently depending on the angle of view on it. In particular, this can be done using Gradient Ramp in Normal mode and Normal Bump .
However, it will be superfluous in this case.
After all, it is not talking about animation, but only a static picture, not on the poured material at the facility, which will appear on all sides.
All you need is just to twist the material plush so that it looked cool in your particular perspective.
For this purpose, the mat of the texture plush and right-minded reflection will be enough.
also do not forget about the usual Bump.
also, look closely at the reference photo. More precisely to the studio in it.
All studio black, and only behind the camera is a bright light source, which reflects the plush side chairs. You have, in the last render, background light.
In this studio you will not receive these reflections as referesnom photo even if the mat is the ideal physical correct. Just because you will not have dark places. . After all, the chair environment - light
There is light at the light, that is, just the texture Plush🙂
Therefore, the studio should be appropriate, so that you can it achieve the desired effect
that is, to what is reflected "whatever" then what is it that it should reflect, to be "as there is" otherwise the desired effect is not achieved.
In this connection, I advise you to simply adjust the cool mat using reflections and bump😉
