Hi!!! I have a new question) I would like to know how to create a window in V-Ray. In my scene I changed the setting, but for some reason, the glass is not visible! (Please tell me how to put the settings to the glass to be seen!)

On the right and in front of a glass wall in front of a table and chairs should also be seen glass.

That's what happened with these settings ... getting better but the glass is dark ((and if you make it lighter just will not be seen (((

Hello!

The V-Ray glass created on the basis VRayMtl material.

The first things you need to start is set to Diffuse - black (RGB 0,0,0).

Then ask reflection, investing in Reflect slot card Fallof, with Fallof Type: Fresnel. The lower color swatch (Side) - should be pure white (RGB 255,255,255), while the upper (Front) - Gray (RGB 25,25,25).
In addition, for a more realistic, reflection should be slightly blurred, setting the Refl. Glossiness, for example 0,98-0,95.

Now we have to make the glass transparent.

To this end, the color must be set Refract white (RGB 255,255,255), as well as for realistic, change the IOR to 1,517. Although, in principle, to change the IOR is not necessary, and you can leave the default value (1.6).

That's how the settings look typical glass material in V-Ray😉

Hello! Honestly, I do not quite understand where the glass? Glass wall directly in front of chairs, burgundy for doors? If yes, then, at first, the glass should be in amount, it should not be flat, the glass should have a thickness. Second, the glass can be embedded into the wall, it should ka who thereto attached. If you do all of it will actually do that is mounting and the glass itself is not votknesh into the wall, and put to her that there was a formal gap that already appear window border. Wink its thickness. Now I do not see the glass borders, so that I am still not sure if correctly understood, where the glass is😁 In addition, that it is still evident - can it be made less transparent, slightly dark color of the Refract, as well is slightly blurred its clarity, reducing the Reflection glossiness to 0.95. In any case, to the scene look realistic materials, the geometry of the scene just has to be plausible, not flat, flying, stuck in the wall, etc .. By the way, the Falloff you Nestroy not as I advised ... be attentive 😉

Hello! the thickness of the glass I have somewhere 50 mm. it's not a plane!) to plan allocated white glass walls. I put the door on the right, so it was understandable for, it can be seen by the way the glass) for the flower end wall. there is a passage and a glass wall in front of chairs! There I also put the door. and with settings like all true ...)

Hello, Xenia. The mood is still falof as previously said Anton, you got the wrong color of the upper. And raise the lower face of the glass, so that it was above the floor at a height of 1mm. Then, the glass will reflect the environment and at the bottom it will be a clear line😉

Hello) I picked up the glass and visible face of the right, but no chairs in front of (((Still excuse me for a silly question but I do not understand that the map falof wrong ???? it is set up as it was written ... (upper ( Front) - gray (RGB 25,25,25) 🙄

4 Nov, 2011 # Re: How to create a glass in V-Ray?
Xenia seems you have incorrectly configured the workspace, display colors of color selector is clearly wrong. RGB 25,25,25 is dark gray, but not nearly black 🙄 This is a sample of RGB 25,25,25 color:
Read a lesson about the use of gamma 2.2 in 3ds max and obyaztaelno followed by all of the instructions there. With regard to the brink of the glass away, simply lift it even higher there 👌

Hi) thanks to everyone for the tips !!! gammyne 2.2 of visibility of my window does not change ... and from Fallof card (upper (Front) - Gray (RGB 25,25,25) dark gray or almost black did not differ when rendering ... I do more or less tuned glass 🙂🙂 Here I would like to know when to put a tick (Fresnel reflections) that represents a number (L) and that changes from its pressing? and color (Exit color) is also pressing the (L)?

Hello!
That honor topic about the use Falloff maps . This topic also explains the essence of the Fresnel reflections. How does the lock (L) you can read in the topic of what is Hilight glossiness .
Regarding Exit color, then look theme of "gray" reflection . There's a situation where, instead of reflection, visible Exit color, due to the insufficient number of perotrazheny.

This is a very useful theme, besides the answer to your direct question, they also will be useful to you as part of the theme of the glass material 🙂

If you have any questions about the material contained in those topics, for example about the Exit color, feel free to ask them right there in the topics😉

Here is going to ask is who knows what kind of table ??? I have gone after her appearance or steel not seen some of the material in my scene !! (((.... Why all the materials can disappear ??? place I have still a lot of free ... (I always save a copy of the scene and then like that once a copy is preserved with the advent of the signs (((and without some of the material (( As a result, both scenes, and this plate is not material (((please tell me what is the problem ???) 🙄

The fact that you have changed the names or addresses of textures and 3d Max can not open them and display. Scene File remembered them along a certain path and under a certain name, and then change the path or file name of the program began with textures teryatsya😁. Somewhere here on the site has been the solution to this problem😉, though I do not remember how the theme is called 🙄, look for the site, it is clear everything is assigned 👌

7 Nov, 2011 # Re: How to create a glass in V-Ray?

Yeah, Dennis, that's right😉

Theme is a way to prescribe the textures in the Max 3ds .

Xenia, please, if you will create a new question, not related to this issue, create a new and ask it there. Do not write all the questions in one subject that was not a dump😉

Good time of day the RS, and in particular you Xenia! I tried to set up the glass mat, for a simple little scenes, like advising us to Anton 👍, along the way saw a very significant difference between a Fresnel Render'ami enabled tick and without - without a tick of reflection and the material itself look much better 👌 . It turns out that you, Xenia, in their settings to apply the double-reflection effect Fresnel. On my sreens immediately noticeable difference between reflections on objects. I think this may be a solution to your problem with the glass material or if not the solution, at least to give realism to your glass😉, try to disable the host material in the glass and make it tick Render. We are waiting for the results😁.

Hello RS! There was the question of how to apply the bump to the material of glass, so that only the one side of the glass was a curve that faces the camera (if you just use the noise map it will be applied immediately to all parties to the glass) and what type of mapping for glass (box, face , planar) do you use? Thanks in advance) I want to get a result like this:


2 Nov, 2011 Anton (Staff Author)
23 Nov, 2011 # Re: How to create a glass in V-Ray?
Hello! Generally there is no problem that the bump will on both sides. If you look closely at this picture, you will notice that the curvature of the glass paintings is noticeable only on tinted windows, while, as transparent, it is almost not visible at all. This further simplifies the task, as the reverse side of the glass models are barely visible through the dark glass. But if you want to repeat a fundamentally realistic bending glass, then it is compacted grid (add segments along and across the glass model), and apply Noise modifier. So you can literally bend the glass, as it happens in real life, as well as to receive the curved reflection realistic😉

23 Nov, 2011 # Re: How to create a glass in V-Ray?
Thank you, Anton! Ps: I understood: it turns out, had simply IOR factor on refraction deliver 1.01😁

Hey, to be honest, I do not see nothing on your screenshot. And even if so, what the actual problem is and how you're sluggish blurred background with clouds reflections considered inversion? 😁 Two objects with highly reflective mat, one object reflect reflection of the other. Nothing unusual 🙄

Good afternoon ladies and gentlemen, I have just begun to comprehend the wonderful world of 3D and hope for your help! The challenge in the visualization of the stack of flat glass plates stacked on each other, setting Wray and material already twisted as he could, but remain dark spots shadows presumably from the ends of these same plates, is it possible to get rid of them and how to do it. Thank you in advance! on the scale do not pay attention! I did not apply the override!

Hello! Judging by the renderer is a bug geometry. Put in the same scene, under the same camera angle, several Chamfer Box with very little Fillet radius. If the "black mud" will disappear, then what has been said above. If not, then we will investigate further😉

Created with champfer box (top right corner) - the first image champfer 0.3 mm; the second 2 mm number of segments 1. In the third already champfer 3 and 6 segments. As you can see the dirt is gone: And as soon as the material tidy daw with Fresnel reflections (1,6) Now it turns out that: It seems, and "dirt" is not glass but as a "predator" in disguise)

Glass is the second most complex, after translucent materials, human skin, for example, material. His "nag" can not take😁 Even very experienced wizards, sometimes do not know how to get realistic glass objects. So you'll have to work hard.

Glass is almost transparent and slightly reflective. Successful visualization of glass depends on 5 factors. It:
(1) - The geometry of the object.
(2) - The right material.
(3) - True studio.
(4) - The true scale of the scene and object.
(5) - The correct settings for the renderer.

1 - They sorted things out with geometry. If you have the same "dirt" on the standard Maxx ChamferBox, then it's not a matter of geometry.

2 - In order not to guess what you set up in the material, whether you need Fresnel reflections, etc., first of all, take a properly tuned glass material to be guaranteed. To do this, go to our section of models and download a model with glass. For example, a set of containers for pasta, or a glass set for oil and vinegar, or a classic wall sconce, in general, anything, where there is white glass. We have many such objects. The result of their materials can be seen on the preview. If you have material in the scene, from any of these objects, behaves differently - smoothly we come to the key factor of glass rendering.

3 - As mentioned above, the glass is almost transparent and slightly reflective, so all of its "material" is essentially what we see through it (it's transparent) with a slight distortion (IOR) and a little bit of what surrounds it (it also reflects Then what's around). If transparency is like everything, then it's more difficult to reflect. The fact is that glass reflections can not look "as in the picture" if you do not have the same thing in the studio as in the picture around the glass, because in this case it simply has nothing to reflect. Judging by all you have a plane with the texture of the tree on which the glasses lie, and all this is in a completely empty studio with a simply black Environment. This black "dirt" in the reflections is the black infinite black space around it.

What to do? Do a studio that has something to reflect. In order not to repeat, I strongly recommend that you read the topic of creating an anisotropic steel material. There just this issue is comprehensively touched upon, for the brilliant metal is even more dependent on the environment than the slightly reflecting glass. Slightly because the glass is a transparent material, that is, most of the light rays, albeit with distortions, but passes through the glass, and come back (what we call reflection) is a very small fraction. For a highly reflective glass is already a mirror😁

4 - As you know, the thicker the glass, the less transparent it is. To understand what is at stake, it is enough to take any glass and look at it in the butt. Immediately, the "perfectly transparent" glass in the end face turns greenish or blue. This is all because with increasing thickness, the ability to pass light rays through yourself decreases. This effect is simulated by the "Fog" parameter. The thicker the object, the less transparent it is. Since the thickness of the object in 3ds max is measured in system units, then its opacity from thickness also depends on the actual thickness. That's why, even the same material in different scenes can look different, because the material is set in mm, and pours into the scene, for example, where the system units are cm. Here we have a 10 times (1cm = 10mm) different "turbidity" of the glass. For more details, see the topic about rendering fluids in V-Ray.

5 - Render settings affect the least extent, but they can also. For example, if the "Global switches" rollout activates the "Override depth" function, it will globally limit the number of reflections and refractions of materials, which is especially important in your case when you have a mountain of objects with refractive-reflective materials lying one on top of the other. There may easily not be enough 5 and re-reflections or ducks (Max depth in the material settings) and you will get "Exit color" spots on the spot where there should be another reflection.

Thanks for the quick and detailed response! Articles on the site of much opened my eyes 🙂 Thanks to all 3D guru for your invaluable support service! Speaking of glass, I have already tried so many things ... Enviroment and was vraysky and hdri studio changed the base material on a regular vraymtl without texture and the material replaced on the advice of your model with the site and cut the polygons on the model), however the result has not changed: On Render model site and my one and the same material (from the model) enviroment vraysky and vray light plane directly over the stage, depth in the material twisted to 50 as subdiv) What else do frankly do not know, but I will continue to twist) After where that is cherished galachka-a button) must be)

That's from a different angle: Boxing I immediately picked it up and turned on it was not dirt, but it is necessary that a certain angle)

Here is a screen rendering, the scene and HDR maps that I put in the Environment: The only thing that I did of undescribed above, it has put a tick «Affect shadows» in the glass material, which, in turn, will allow to take into account the refraction of the formation of the shadow under the glass objects and make it barely visible and not considered glass objects are fully opaque and form underneath dense black shadows through the transparent material will appear as dirt, spilled a glass. From the above (subject about fluid rendering) nuances, special attention once again to the mutual intersection of transparent objects. It directly affects the final result. In particular, I placed the glass on a small distance from each other, ie the verge of glass objects (Chamfer Box with very little Fillet radius) do not apply. As a result, no dirt and "predators" under glass there. The only thing that does not look very artistic, HDR is a reflection of the cards in the corners of the third and the second glass, but it returns again to the question of the studio, over which need to work even more than themselves on glass, so everything is in your hands. And another point. You have some glare glass near the plane (with the texture of wood), similar to the caustic. If it is a caustic, then disconnect. Bring to start an acceptable result without it. 😉

7 Apr, 2016 # Re: How to create a glass in V-Ray?
Brilliant! 😁 Here is the same tick "Affect shadows" That's it then, and I needed the turns. Anton, thank you so much and low bow, I would have to guess the tea leaves is not yet known how many 👍 I think the noise will remove subdivs light, and the rest is a matter of technique. That's about a shadow that I did not think at all)
