Hello RenderStuff! I appeal to you on the following question. Long searched various forums how to create a matt (sandblasted) glass options ... to be honest it was a lot, but none satisfied me. or the glass was too muddy or too blurry. Honestly, I wanted to create something like this, but the glass turned out like this - a dull gray, but the image does not seem very blurred .. on the coffee table it looks more or less acceptable to him, but in this case a suspended closet reminds me a thin mosquito net, not frosted glass . how to fight? add a texture (eg noise) in the bump or use use interpolation (though so it is also not very realistic)? RGB colors are used on the 255 diffuse, on 10 reflect; 210 to refract. Yes, he mat here

matte material (frosted glass), -! Is a very simple mat.

For the foundation you need to take an ordinary VRayMtl .

Diffuse it should be as dark to frosted glass was not as white as you have, and the dark, as in this picture thee. It can be black.

Then you need to give a bit of reflection. Do Reflect slot slightly gray. And do not forget to blur the reflection, reducing the value Refl. Glossiness.

Now transparency.

Do Refract color light gray, almost white.

The lighter, more transparent mat.

In principle, you can make white, too, will look good, but the sandblasting is still not entirely clear, because it is glass, polished jet of sand.

And now blurring the transparency to objects behind the glass It was not clear and blurry as you need.

To do this, one may say the value of Refraction Glossiness. The lower the value, - the greater the blur

That's all

The specific values ​​in your case is not appropriate, you must own to your liking customize material

<... p> Create the mat. Apply it to its façade and render.

render region only this facade to bestolku not pererenderivat whole scene for the sake of one glass façade

Did mat -. render. What is not satisfied? I figured out what is wrong and render again, and so as long as you will not achieve the desired result.

And yes, another check in the V-Ray :: Global switches whether you checked Glossy effects, because for Refraction Glossiness 0.85, how are you in the mat - blurring objects behind the glass is very small. More precisely, I do not watch it😁

Renderstaf Hello! My question is: do I need to do white frosted glass chandeliers, whether the setting is somehow different? So I poprobyval: to say the least "once a failed"🙂🙂 is, of course, render at low setting - close to the rough, but when picked settings iradens MAP and spotting light cache is not lost (seen in separate otrenderinom region). Material Cover: in difyuze map colorcorrect adjusted under the range of 2.2 and white in Reflect kartka Fallof settings like this # 2090 of the lighting of the room there is only inside the spherical lampshades vireylayty 30 subdivs, zakarniznaya lights, well outside vraysun + vraysky lowered with the sun below the horizon. Maybe I did wrong, that the main source of light inside the lampshades? It may be necessary in light sources only to slightly illuminate ceiling inside themselves, and the main lighting as something different is done? Prompt how correctly, please) that's necessary to achieve this result for lampshades I am hope for your help)

Jura, hello. I can not tell you right - renderstaff will correct, you should transparency of your lampshades 100 potsentov, it is fundamentally wrong, because matt sandblasted glass is not completely clear and allows light only a little compared to your settings. Tell me what you specifically need - to emit light diffusers or burned (as in the original). From this and we will make a start ...

Good evening, Gus) Thanks for the reply. Here I refrakt not completely white, but somewhere 195-195-195 ..... but this is probably not the point - it's still almost completely transparent material. In this situation, I need to set up evening lighting (ceiling lamps to emit light).

Hello, Jura. It seems to me (she just learning), in this case it is necessary to examine the material itself. Reflection almost no gloss, too, the material is transparent, but a little - a little. But all of these properties apply to the lower dome, where it is not, ie, the lights are turned off. And what will happen if we include ??? Ceiling lights, so much so that it will be difficult to watch, especially to distinguish between some reflection, refraction and transparency. In my opinion it is necessary to apply to the lower dome usual wee ray light MTL, adjust effect and color glow. To put into the wee ray IES, forward on the table. Itself tried, but just nothing good came of it. Here's an example of my clumsy, unfinished scenes: circles, stains, etc. But I think that in my case the matter is not in the material, and the source of light from lampshades - put IES- get divorces, put fotometrik usual, all is well, only the light from it is obtained a general, not directed ...

Hello, Gus. I think that in such a situation to use vireylayt ieski material and inside is not very correct, but maybe I'm wrong. Because this type of lamps (like you and me) serves to uniformly diffuse light cuisine (not just the dining area, but the entire kitchen as a whole). If you use the material vireylayt, then he has to cheat large values, or install additional invisible light sources for ambient kitchen lighting. And what about the reflections and transparency in the ceiling material you my good I suggested - I somehow did not initially thought about it. I set the Reflect color to black, and the intensity fallof card reduced to 30%. And refrakta color made darker. And eventually stains are gone (even with rough render). But all the same to me is not a very pleasant lighting. Perhaps inside lampshades need to install visible spherical vireeylayty with low intensity and short-range only to illuminate themselves lampshades (as if to simulate real light bulb), and the upper and lower end of the ceiling to install invisible spherical vireeylayty with more intensity and more radius already directly for room illumination.

Jura, hello!

In your case, it is not in the material, and in the technique of the internal illumination in V-Ray. Read the topic, about, how to install lights in the ceiling using the V-Ray, and only then go on to actually issue setting the ceiling material😉
