Sobsno question to experts: what is needed in the setting of high gloss Reflect that it gives, in what cases applies and what it (what cards) eat? 🙂

Hi, In order to understand how the gloss (English glossiness [ 'glɔsɪnəs] -. Luster, luster!) With V-Ray materials, we need to understand that, what is gloss or shine in the real world from the definition of gloss, it follows that it is - the relationship between the intensity of light reflected from the mirror surface and diffuse sveta.To is, in fact a characteristic of the material, showing how the diffuse color can be seen under his reflections, or through reflection. You can guess that the stronger the reflection, the less visible diffuse color materiala.Esche, an important component of reflections, such as blurry, a flare . That looks like a bright light spot in the reflections, then there is in fact a literal, but blurred reflections of bright sources sveta.Sobstvenno those same effects and simulates VRayMtl.Za gloss, ie the reflectivity of the VRayMtl, responsible option Reflect. The brighter the color, or color Reflect card embedded in it, the higher the reflectance of the material that is above its glossiness. Of course, the higher the gloss, the less visible underneath the diffuse color or map, embedded in the slot Diffuse.Davay take VRayMtl and set the diffuse color red: Look at a sample of the material, it's just completely red matte surface Now add to it the gloss (reflection), setting the gray color in the color slot Reflect. Note, as it became clearly visible reflection of the environment (colored squares) of traces of the parameter the VRayMtl reflections, this is the Hilight glossiness.Chto makes Hilight glossiness? speaking literally, it selectively strongly blurs, bright reflections on materials. Those which are obtained from the light sources or bright luminous material on other sites (which is essentially the same). That is, the reflection takes in excess of a certain threshold of intensity, and strongly "smearing" them, turning into a bright white spot. That is, create the same blik.Parametr Hilight glossiness, and in fact is responsible for the degree of blur of bright reflections. That is Hilight glossiness, is the power of spreading (blurring) highlight See how on the material appeared a bright light spot, while others reflect the value remained below neizmenny.Chem Hilight glossiness, the better the degree of blur of bright reflections. Unit - no blurring, ie 100% gloss. Values ​​less than one means that the lower the gloss, that is the reflection of bright light sources razmyty.To same can be done and, in fact, with the rest of the reflections in the material, that is reflected not only the brightest sources, but also everything else, that is the environment , objects near and so on, in this case, a chessboard envayromenta.Za degree of reflection blur, that is, how to be the perfect gloss material, the parameter responds Refl. glossiness.Esli Reflection glossiness unit, it is a perfect luster, that is reflected not blurred at all. If the Reflection glossiness is less than one, it means that the material does not have a perfect reflection. That is, the lower the Refl. glossiness, the reflection blur See how not only highlight, but are themselves reflections underneath steel razmyty.Vot actually vse.Po default Hilight and Refl. Glossiness connected (clamped lok L), then there is a numeric value in the Refl. glossiness and gloss determines blur and glare. Unlock them, you can independently control the glossiness of the normal and Highlight (from the English high light - strong light.) Make up😉

👍 🙂 exhaustively !!! Thank you. Maybe not quite in the topic, but could you give an example of setting waxy luster material ... and if you can explain more pozhalsta question blinn ward and phong ... PS thanks in advance)

Hello, Alek85. With regards to functions BRDF Blinn, Ward and the Phong, read in a useful discussion of how to simulate the anisotropy in-Ray the V (post # 1117).

If we talk about the "waxy luster," then, in general, it is no different from any other. We must start with the fact that the wax can be different as matte and polished, so the presentation of "wax" shine in different colors. To adjust the brilliance of the material in V-Ray, be it wax or something else, all you need to do is find a picture of the desired material. Then, carefully examining it, just pick up the desired value Reflect, Hilight and Refl. Glossiness. Very trivial and very abstract and very much in common? 😁 Yes, it is. No material adjustments "shine wax" or "frosted tree." All values ​​every 3d Visualizer picks to your liking. Solely on the eye. In this regard, some have the picture look realistic, the material is beautiful and brilliant, while in others it is sluggish and synthetic. Each owl subjective sense of the concept of "waxy" finish. If he does not handle it, then just pour a sample here (photos) of the desired material and I own subjective taste of his mood, either you find a ready-made mat on a 3d model of the site😉

There is a problem, after the material is placed in the range of 2.2 Editore, and it is expressed in the following: it is impossible to properly adjust the reflection materials. Example: before it was like - if the mat for example a dark (almost black), then do gray refrakt, put the check Fresnel all mat already reflects, after I in gamma settings tick "use to the mat Editore" was to happen the following: We take the same material as the "dark (almost black)" put the check Fresnel do refrakt gray and he did not reflect, even if put refrakt completely white it still does not reflect, even if fallof throw in refrakt exo falls very cool podshamanit to mate started reflect ((((what is the Trouble?

Hello! Did you mean Reflect, instead Refract. RefRakt responsible for transparency, rather than reflection. For reflection is responsible Reflect😁 In general, the mat out with the settings screens, as well as renders objects with the same mate😉

and how to lay out the screens? 🤔

in this version of the classic setting Reflect, which stopped working (((with the result, respectively. Please note that the Reflect MAXIMUM white! something wrong in short ( There Fallof setting with a map, but it is a necessary measure, although there were reflections, but the Fresnel effect began to work the other way around, as it were, that is, angle does not reflect well if you look directly at the surface of the peel as a mirror (((

None render settings or range, in this case, there is nothing, you have a very simple mistake in the settings of the material. I'll tell you tomorrow😉

In order to understand what will be discussed below, read through the mini-splint for use Falloff maps Reflect slot . In particular, pay attention to the fact how the adulteration or mixing Fresnel reflections from the mirror images. Just try to get to the core Fresnel reflections, there are also described. So you will be easier to understand what is happening in your scene.

Your first rendering, with the Fresnel reflections, in the properties of the material, clearly shows the dependence of reflection intensity on the angle at which we see on the surface.

When Fresnel reflections, than we perpendicular to the surface, the intensity of its reflections below, and vice versa, than in parallel, the reflection intensity.

In a scene, it suffices to apply the same mat on stoleshku whose surface is to be almost parallel to our eyes, you immediately see its reflection. In fact the same applies to the side wall of the furniture unit, which is also pretty well reflects, in contrast to almost frontally looking at the facades of us.

On the second renderer, you applied fallof card, which at current settings, the lower the color slot is responsible for the Fresnel reflection, and the top, with the specular reflections. Make the top slot of the color black, and you learn the same rendering as in the first case with an activated Fresnel reflections in the mat and light color Reflect.

That's all.

🙂 I understand everything, just as an example to say that before I did not resort to fallof map well, or very rarely, because when using blunt daw "Fresnel" and matching color setting Reflect everything was OK, especially the darker material (and I have it almost black), the better it reflects and tekschih settings (white reflect) should reflect and be perpendikulyarno..ya almost want to say that I can not get this level of reflection here: those. I used without any fallof a mat easily done, but right now, even setting a "white" Reflect he does not want to reflect almost entirely 🙄

You just can not use Fresnel general. That's all. Why would he do, if you want to get a mirror reflection? Put yourself simply Reflect gray and all. Why invent something? You that Fresnel need "for a tick"? Work on the result rather than the formalities, especially because they do not appreciate someone😁 Fresnel PF, Reflect gray and forth😉 But if in this case does not reflect the case is already in smoothing facades. It will be necessary to correct the model.

17 Sep, 2011 # Re: Highlights management with Highlight glossiness in VRayMtl
🙂 But not well, just want realism🙂🙂🙂 Well, let's say, in this perspective, spit on Fresnel, and if we say, and will be in front of the same bedside stand with the same façade (vsmisle mat) it is even and glossy, but smaller vseravno should reflect 🙄 .... well, just as it is in the head by default already😁 that Fresnel on everything except the mirror

The mat or falofe, if you want, when Fresnel Fresnel IOR Change or Override Material IOR (Index of Refraction). Now you should default 1.6. Put 2.0, 3.0, 4.0 ... in general the taste and you will have but with a Fresnel mirror images 👍

👍 Okay, Thu sales did not think about it. THX. but can not the topic a bit to indicate verbally or by reference to the discussion because of what I have so "burn through" ceiling window. your settings. 🙂 They are very much like me

Hi, really need help. How can you visualize when the subject views from the front, with no corners, get a flare? That's how I need to: That's what it turns out that I have: I like a white spot, and they have a clear varnish with glitter.

About the transparency of the highlight seems to me this is fixable by means VrayBlend. Just do it, and set up in a varnish layer the degree of its luster and transparency. A form of flare only solution seems to me - this is the correct geometry. After all, on a flat surface is flat and flare, while the curved surface on the skirt will highlight its shape. Although I do not rule out the possibility that this fake web effect that is added to Photoshop. There vario ESO, that this effect is achieved by setting the reflector tricky in the studio, which gave a glare. I think you can try these Varian, and focus on the one that will suit you.
