Hello! Worried about the question of why in the coverage of many interior scenes using vraylight windows + vraysky + vraysun? After all, if you use only vraysky with attached and disconnected vraysun, you can well enough to illuminate the scene. And in general it looks physically correct.

Hello, Renovacio! Everything is quite simple. When illuminated interior scene with the help of a bunch V-Ray Sun and the Sky, with the exception of direct sunlight on the VRaySun, the main source of light in the scene is a secondary illumination emanating from parametric HDR VRaySky card. It is obvious that very little of the diffuse secondary illumination VRaySky can break into small interior window openings. Because of this, when a lighting scheme leaves a strong glare of the portlets, with simultaneously low light indoors. In addition, the secondary light from VRaySky, being GI , has all of its disadvantages. Firstly, as the indirect lighting, it can not generate a photon caustics, and secondly, there is no direct possibility to regulate the quality of the shadows. The only thing you can do is extremely inflate settings engines indirect illumination. But the rendering time will increase several times, and it is likely that a complex aiene will not get rid of noise in the shadows. And yet, the most unpleasant is that, in contrast to the shade you want to sample a direct light source, in the same the VRayLight, the shadow of the secondary light source will be blurred and indistinct. This manifest lack of small shadows on (and under) in small objects. For example, a vase on the table will not stand, casting a small shadow on the surface of the table, and the impression is created that it floats over the table, because it is a great stain smeared instead of a small shade on a table. Returning to the topic of discussion, I would like to clarify that VRayLight in window openings, with interior lighting VRaySun + VRaySky, not commonly used in the nominal mode, and skylight portal mode. What does it mean? This means that VRayLight will forcefully "catch and let" the interior of the secondary light rays emanating from VRaySky. If to speak more correctly, it is actually a source of light in this mode will shine with color and intensityawn, taken from the secondary lighting, with literally not a portal. Thus, you can completely get rid of the problem of insufficient GI passage of scattered light rays into the interior, as if concentrating them in the window opening. Also the VRayLight, as a direct light source can generate caustics without problems. And most importantly, why set VRayLight in window openings with the interior lighting VRaySun / VRaySky system - a complete control over the quality of shadows in the scene. In this scheme, lighting, shadows quality freely adjusts itself VRayLight.

And I anyway do not understand much. For example why "the main source of light in the scene is a secondary illumination emanating from parametric HDR VRaySky card." ? And why not use only VRayLight in window openings make them opaque and adding texture to the environment map for the species outside the window? Why use just such a bundle and which generally have a solution for the normal lighting interior scenes? What solutions are you using (RenderStuff) such as in a scene from the lesson about creating a virtual 360 panoramas?

Hello, mOPs. In a scene without lights, with a GI on the map and the assigned slot Environment Map Environment and Effects window, Environment tab, the only light source is the Environment will be with the intensity and color of the map. This is the principle of 3ds Max. In short, the Environment essentially is a sphere of infinity from the center of the scene, which stretched map, the one that is embedded in the Environment slot. And no matter what stands in the Environment slot, a color bitmap texture or HDRI map. It will be stretched to the sphere and the sphere will radiate in the secondary stage lighting solid color, through the raster map through HDRI map. In our case, in the Environment slot we put parametric HDR map VRaySky and it it will shine Environment sphere. Some professional 3d artists wishing to personally control parameters GI glow of Environment in the viewport, set the scene in the sphere of enormous proportions. Assign her luminous material such VRayLightMtl, and stand% B2lyayut in its appropriate slot desired map, such as the same or pretty VRaySky spherical HDRku with clouds and blue skies 🙂 Usually this technique is used for visualization of exteriors. In the above technique, in fact, used VRayLight where texture is not inserted into a slot of each light source, and assigned globally. That is, all light sources used Environment texture. It makes no sense to mess with the installation of texture in each light in the windows. Imagine the situation, when the room has not one, but six windows. This force is busy with each of the six sources. Not only is the texture control VRaySky not very difficult. While as VRaySky fully parametric, and even in conjunction with VRaySun its color and intensity depends on the position of Sun. Would you like to day? Raise VRaySun high in the sky. Want a night or evening - Lower VRaySun the level of the stage. Global monitoring of all emission sources VRayLight scene mode intensitySkylight portal - generally a separate topic. It is enough to change the setting Sun intensity multiplier VRaySky card, at the same moment in all VRayLight Skylight portal mode will change the intensity of its glow. In the case of independent VRayLight you will not only busy with the adjustment of brightness and color texture, installed in the Texture slot, but also to suffer with the change and the selection of true Multiplier value for each of the independent VRayLight. Especially the "beauty" is a case where the different size of the window and choose the correct values ​​of intensity VRayLight different geometrical dimensions will be very difficult. Of course, you can wind up with units measuring the intensity Radiant power (W) Units, in which VRayLight light intensity does not depend on its geometrical dimensions, but why so complicated? Such a quest when you set up each scene can take place except by boredom, is not receiving any benefits at all as the image. Bundle V-RaySun + V-RaySky complete with%B8stochnikami light Skylight portal mode is the normal solution for lighting interior scenes. That it was used in a scene from the lesson on creating a virtual 360 panoramas 😉 As for the new lessons, it is one of the most frequently asked questions. So we decided to create a separate topic about the new lessons RenderStuff .

Thank you. There is another question - how to properly place the VRay Light in the Skylight portal mode in windows premises? Outside, inside, directly at the opening? If a lot of windows, it is necessary (recommended) to put into each, or you can tell one from the outside but on the size of windows all together?

Very nice question😉 In fact, there is no uniqueness. You can get an excellent rendering and light sources, light inside the room and Light them, exactly as with a single Light's on all the windows, and even with individual lights o for each window. This whole saga about placing lights o the window started from the time when the primary GI engine secondary bounces was ftonnaya map , which was created on the principle of action-rays (photons) emanating from the light source. If the path of photons met some object, they simply vrezàlis in and sampling the rest of the scene took place only remaining part of the photons. Placing lights, emitting photons outside the window of the photons vrezàlas in the window frame of the window and did not reach the inside of the room. At the same time in the "lost" photons consumed computing resource, and used promptly% D1 memory that was completely irrational. In modern versions of V-Ray, a bunch of the most commonly used Irradiance map + Light cache devoid of this shortcoming. These GI engines, in particular LC, replacing outdated Photon map engine, sampled from the camera to the light rays, not vice versa. That deprives make any sense lajty indoors. It will not bring absolutely no savings. Moreover, if the window a short or no sill and translucent tulle lightly against him almost tight, if light is required to put to rest with the geometries of any window handle, which in turn easily cause artifacts in the scene on glossy objects and GI maps. It is much easier and more convenient to place lajty outside. It's very simple. All that is needed is to make light a little smaller than the glass in the window, so that it is not shining on the window bestolku%80amu. Then, in the model of separate windows (Editable Poly => Polygon / Element => Detach) glass themselves and exclude them from the lighting and shading of the Light's (VRayLight => Exclude => "name detachennogo glass object"😉. To the exclusion of the lighting / shading easier to look detached from the model a model glass window, it should immediately call the right so that then it was easy to find all the objects to the exclusion of the list of names. If you have a model of the glass and the window frame was originally selected, the task becomes even easier 🙂 For example, just such a 3d model of windows with separate panes . The same exception to the shading should be done and tulle curtains. Thus, it will simplify the sampling stage, not causing light to shine through more translucent materials, greatly speeding up the rendering and proactively ridding it from noise and other artifacts associated with the passage of light through the translucent coree material. At the same time photorealistic visual fizkorrektnost and the resulting image will be fully preserved. Many are worried that after such an exception, glass, curtains from the windows and translucent tulle will be dark, as they are not exposed to direct light from the Light's. But this is a complete fallacy. Though they are not exposed to direct light from the Light, it is well compensated by the same bright glow Environment GI with V-RaySky. With regard to the number of lights o windows, too, just here. With the concept of the above productions Lisa outside the window, you can easily put a light on a few windows, if it allows the geometry of the room, the main thing that did not suppress Light scene objects. The only but is that the window in the center of the partition Lite will be a little more marred than at their edges, but it is not so important, how significant savings in time and ease of rendering some% D Management0 Light compared to several. As stated in an earlier post, you can still put a light source into the room by the window and make a window for each light source. It will not make a scene worse, but will not do better. Just take over the hassle of setting up lights, except the ones necessary objects and so on. You could customize the scene, but is that of boredom 🙂

As is known, many are advised that when placing VRayLight SkyLight Portal in the windows, you have to be very careful not to allow the suppression of other geometry, and in particular with the same window. That is, it is necessary to place a portal or a bit outside (the street), or slightly inward (in the room) Well, if in the window, but make it a little smaller window opening. In one of the lessons observed such a method: Snap mode is activated to the heights of the model and placed safely portal hair's breadth on the size of the window opening and thus comes into contact with the vertices of the opening. And all perfectly lit and no "do not let the intersection with ..." and other horror movies 🙂. I would like to hear a comment about it. And so it is not clear why all these intersections can not allow the portal to the geometry - a bug VRaylight, 3ds Max or glitch is the popular belief? 🙂

In general, the absence of the desired intersections of the light sources is not only VRayLight SkyLight Portal window. This applies to any source of light in the scene. This recommendation is due sometimes occurs in the scene artifacts. In particular, at the intersection with the lights o geometry, the GI can strew the whole scene bright spots, unavoidable by any means. In general, it is a bug renderer associated with the fact that the brightness of light sources far beyond the RGB range, which is being anti-aliasing rendering and calculating brightness samples GI for the formation of the final RGB image. When the light source intersects with the geometry, it may happen that the point of intersection of the surface geometry of a very high value of brightness. When calculating average values of brightness of pixels during rasterization , the renderer simply takes the total average brightness, where one of the values in hundredsand times the limit of the range in which to see the calculation. Therefore, whatever nebyli other values, the result will be equal to the value of maximum brightness. Now imagine that this peresvechnny object is reflected in the materials of the other objects in the scene, giving their faces the same super bright samples. The situation was exacerbated when miscalculate primary and secondary bounces . From this point of overexposed fly thousands of secondary light rays, which are strewn scene disgusting light spots. Why is visible light sources do not give these super bright samples, because they are, in fact, is their generators? Firstly, it gives very often manifests itself as small rash glossy materials, and, secondly, V-Ray nevertheless takes into account brightness of light sources and calculates their correct, while overexposure geometry due to the intersection with the lights, the situation supernumerary. ATBehold, it is worth whether to adjust the geometry carefully under lajty? It is no secret that many airlines on aircraft is forbidden to use mobile phones to avoid their impact on the high-precision on-board equipment of the aircraft. However, no study has proved that has any effect on the aircraft instruments, mobile communications research rather show the opposite . Nevertheless, the risk of crash is much worse than the inconvenience of not using mobile phones. That is why the airlines are trying to minimize the danger even on the level of prejudice, because it is still easier than to deal with the consequences of the disaster 🙄 Also with Light, nominally should try to do everything right from the start without being destiny. After all, this bug - accident and does not necessarily manifest itself. And if manifest, it is possible, regardless of the% D is crossed0 I long hours to figure, what's the matter. Whatever it was, the benefits of fuss with scrupulous reference Lite dimensions to the window in no way justified. He did not have anything else anywhere match, just to stand outside the window or in front of him and stopped with the geometry of the window and any other objects in the scene. Paste, scaled, forgot all 🙂.

Naugal v-ray sun is a vector, it has no beginning or end, at least in the scene can shove it🙂 But from his angle depends on the intensity and light temperature (color of the sky) and of itself the most sunlight. If you think it is better to photons what would they fall into the box. And so I think all)

Privet.Vse true. Artem says all right. Container VRaySun only specifies a vector defining the direction of light rays direct VRaySun, as well as managing the VRaySky card, tied to VRaySun.To there, moving relative to each other container VRaySun and Target, you just makes Sun shone brighter or dimmer and slightly affect the color of his svecheniya.Na practice is so little change, at least the color, what to say about a very exact position makes no sense. All eyes on. Yes & quot; & quot ;, craftsmen are trying to simulate a particular time of day, use the built-in 3ds Max helper - compass Daylight: System . They set it in the scene and pritachivayut VRaySun containers to containers Daylight, previously exposed in its parameters right time of day and even the time of year😁No a waste of time. This does not give absolutely no benefit as compared to the VRaySun, well-placed just & quot; eye & quot; means .What correctly on the eye? Yes, in general, all at your own discretion. Put - Render. Like - leave. I do not like it - dvigaesh.Tak for a couple of attempts you will find the most successful for your scene polozhenie.Chtoby not make a mistake, you can always place Target rank in the center of your interior (in the geometrical center of the room on the floor), and the the VRaySun, placed in front of the window, so, that it shines inside. Slightly obliquely. On Z can have VRaySun about the height of two of its interiors usually this situation is universal for all day scenes. And occasionally there is a need to correct the situation or target with VRaySun. But then again, entirely on the eyes 👌

In short, when the skylight portal lighting level is already regulated VRaySky card (or other, eg HDRI map), which is embedded in Envshronment slot and is the main source of lighting in the scene. Although I see you're already there, "Heritage", then I read the topic. Perhaps casually. There is also a short splint on the VRaySun conjunction + + the VRaySky VrayLight http://renderstuff.com/remove-render-hotspots-deal-nuclear-light-vray-301/#1293 Try to do everything in his stage sequentially as It described therein.

12 Mar, 2012 # Re: VRayLight inside openingns in V-Ray Sun and Sky interior lighting

It is necessary to adhere to our recommended renderer settings in the POI including for the DMC a Sampler , changing them only when a specific need and in its sole discretion.
I, for one, is less than 0,01, Noise threshold is not set. On the other hand, I can do more to speed up the rendering test .

If you think that you need to reduce - to decrease. Information in the lesson more than enough so that you can make their own decisions about it. If you do not think or do not know whether - do not touch. Leave our recommended values😉

Almost always I struggled with this for closing the lajty room, but your recommendations become lajty put inside the room. Tell me how to get rid of these overbrights with internal lights o location.

14 Mar, 2012 # Re: VRayLight inside openingns in V-Ray Sun and Sky interior lighting

Hello!

Firstly, there is an unshakable rule: "Light must never intersect with geometry." That in your example is broken.
Secondly, in a normally decorated interior, the window opening should always have a window model with a window frame and glass in it. In this case, the window frame will play the role of a bounding box that does not give the GI a glow to the environment, shine through the slopes and the ceiling behind them.
Thirdly, according to the first point and simply on the basis of practice, there is no need to put light just like the window opening, and even the dimensions of the glass in the window frame.
You can easily make light smaller dimensions. This will not affect the quality or rendering realistic.

And then, in your pure white box, despite the presence of 2 huge openings - half darkness. This means that GI, outside the window, you barely shine. If you bring it to the level at which it will not become dark in the room, even with VRayLight portals, especially if it is not pure white but with dark materials, then only GI glow from the same VRaySky will burn you and slopes and ceiling. So VRayLight here in general, nothing to do with when it comes to peresvetah on the ceiling.

On this, completely get rid of them on the render, without twisting the color of the mapping, in the direction of deterioration of the contrast and saturation of the entire render - will not work. The only way out of this situation is rendering in HDRI and the subsequent post-processing of the over-exposure zone. It sounds scary, but, in practice, it's very convenient and simple😉

Now, having gone from the lyrics go directly to the point. Question about VraySun & VraySky, before I put them with your optimal settings, render room lasted 2-3 hours and I was happy as a pig in oranges (the computer I did not, "Wah-wah ass peach"😉, and the picture was obtained by no means "give him the money on the PC," but here's the thing, I used to yuzal VraySun & VraySky exclusively with the settings as they were when the only places them in the scene. Then I went on a method VrayLight skylight portal and did everything as described in another tutorial with VRaySky, where VraySun disabled, etc. (I can not now find the lesson), and in short, putting all this beauty I get render the same room with the same settings many times more (I did not wait for the end, because I still do not want this option three render) finished on the fact that he was rendered 6:30 and there were only 35% of the final stage of rendering. And now about the main thing: SAVE !!! I want windows with light normal, but not at this price. Maybe I did wrong? PS How do you register? Have not found. Not blonde self. Ivan. 🙂

Hello!
We do not have registration .

As for your question, it is quite possible that by placing the portal and changing the render settings, the rendering time has changed. The portal always rendered longer than VrayLight in standard mode. At this point there is nothing you can do. So long as your computer does not become a "wah-wah ass peach", or you do not use portals and revert to the old settings, of course, to the old quality renderiga, or update the computer.

Naturally, 35% - 6 hours is long. But you can vozozvatsya recommendations for test DMC sampler settings . Lower the rendering quality and then gradually increased to as long as the ratio does not quality / time will be acceptable to you😉

Then I decided to open this house scene, a couple of textures added light and I did not touch the camera, and render the program generated an error, then I removed the vray san and his re-built, and that's what happened: And no longer produces errors, and blue image plus a top oblique black strip ... With another camera render image black. I open another file, render the image black. Right now I'll try to reinstall the program. Plus it gives a bunch of perpetual error: Open 3d max, start working without having to open any scenes, anything over 5 minutes, the program generates an error and closes) Run the program, a window appears before the launch: 3D does not love me (thank you)

From version mismatch, that is, you put virey a different version of Max, setting up Windows itself, which does not give the right of access to the system folder.

Certainly not v ray 1.5 SP4a - starinchaty, read on forums and toreentah which version Wee yard for your Max optimal. I've been looking for Max 2013, hardly found, but it works like is good.

Tell me why virey light in sosotoyanii skylight portal noise is much stronger than he is only in his usual form (with a check mark visible)? The light sources are installed in the windows of size, relative prerd frame interior.

Hello!

Abstract question, because you did not show the exact settings Lite. I can just randomly say that you did not activate Simple tick.

In short, in the VRayLight Skylight portal mode, it does not shine its light, and the color of Environment for him. For example, you in the Environment is some HDRka , so he did not shine in a different color, and the color of the HDRki, as if projecting itself through its glow, ie it acts as a portal environment for a light. So now, for your portal is not a pure Environment, a frame with glass, through which all the noises, etc. It breaks the light from the Environment. So he makes a noise. It is enough to activate the check Simple and VRayLight will ignore the geometry behind it, an indirect working as a pure portal Environment. At the same time and become lighter.

If, however, you should tick the Simple, it is still to be understood that the light to sample on the basis of what is happening behind the VRayLight, render engine is still more difficult than directly emit rays of light from the Light's container without relying on additional information. Therefore, light is not in the portal mode noise is less than the portal draws information from the light behind him.

Hello, I do the bathroom and was thinking how to properly put lighting. Lighting is night, it is the main light candles on the floor and wall lamps. In general, to be dim and romantic. For I am going to put a candle spherical vraylight, luminaires probably too vraylight. That's more I do not know how to act, whether to use or put VRaySun VRayLight in portlets or manage only spherical vraylight. I wanted to know how would you put up with lighting angle of solving this problem. And correctly, apply a texture and put pots and set light to it or vice versa? (How are you doing?) Thanks!

Hello, I'm using 3ds max 2010 + vray to him. There is a problem: put vraysun and rendering shows me a vivid picture noise. How to fix it? Here is a screenshot. If at all, without lighting - black picture, if the standard coverage Max - a lot of noise.

Probably, it is necessary to have the vray settings change. What - do not know, you should not put the case 🙂 You do not vray RT render, by the way? as clearly hints red sign in the corner. 🙂 Start with the standard settings, which are given on this site. ps Russian 3dmax Oo

hi! thank you guys for such a site ... almost everything I know I learned here ... I have a question about coverage recently of course ... like a thunderbolt struck the simple discovery that the window at me looks like something strange ... or rather the lower part of the window is illuminated by an order of magnitude weaker than the top ... that is 1/3 of the window sill and the bottom darker, brighter and higher in the full glare of the top ... like think so? ... look in your the window in my room, everything is right ... at the top of a shadow in the doorway and on the frame, and the bottom of the window and the window sill ... perfectly lit reviewed hundreds of other jobs ... so many people so the top of a nuclear explosion, the bottom of the dark ... and only for a very decent renderers everything it looks absolutely correctly and properly. Well, that's a little picture ... but the bottom line is clear ... my middle ... light is like a bud that is not the top and bottom ... all of the recommendations from this site certainly met ... certain post-processing is also not the last thing, but I was not as it is not clear why the sill and the lower part of the window the dark .. .a flower is brightly lit by the light? the color of the window sill is not particularly affected by it ... Reflect course, but not much ... a portal in the window is not large, and even dropped below a bit ... well, I have no peace ... prompt what's what ... please

Hello, I need advice! Here there is a photo that I would like to repeat a maximum of 3 d. The photo shows that behind the glass door there is space, which then has an opening on the street. The question is - where to put the window portals and how much? In the doorway to the street or the inner door or the Veda? How, then, is to do? The stage building has not yet begun, trying to understand the essence and how it's complicated.

I understand that this picture is also 3D, and not entirely successful in terms of photorealism. Here abnormal shadow (from the desk and a chair, for example, in different directions). And the light falls, apparently, theoretically from a large window (presumably), plus, at the very stage there is some additional power, it seems to me. What exactly do you want again? PS: If this is true, then tomorrow I can check with a specialist in the world, what exactly this photo is not so. The artist around the world, not modelers but as a rule, he says, it immediately becomes clear that it is not so. And how should the incident light.

No, it's a photo. I'm a hundred percent not sure, but there are colors found nowhere else, and the same model of the sea horse. Look at the pillow, its texture, look at the ceiling and the play of shadows. I think this image, and it is very successful. I do not know if I have already erased the boundaries of understanding .... Although ... Maybe you're right. In any case, I'm interested in the approach to the heavenly portals such premises. I think they should be put directly into the outer openings. And maybe in the internal, but they should be excluded from the influence of external. I do not know why, and ask, such situations have not yet met

Hi, in my experience, that the interior fotoshoot leads, so to speak, all the rules of the studio. With this, I repeatedly encountered. If filming is to catalog or magazine, then one does not fotkaet interior "as is", if only because the light from the window - a nuclear explosion. Take and sfotkatsya phone, you can try out here right now, take a picture of a bright room without a nuclear explosion in the window and it did not happen. You can not take pictures of the interior of the room, with a small window, to make it equally clear blue sky was visible behind him with a chest of drawers and a sofa facing him . Have to reduce the sensitivity to the level of the sky, which automatically leads to almost total darkness in the room. And here begins a studio light. Searchlight, lenses, flash ... It I to that reproduce the interior with a photo (or visa) only the light goes out of the window, it should be borne in mind that there are likely additional light sources offscreen fully covering the various elements of the room.

Anton (RenderStuff), worse. Outside the windows too often stands studio lighting, and glass hung outside color filters to create the desired color temperature.

Please tell me if in the interior of a large bay window and another set of flaps, then have to put a lot of vray light portals. At this time, the rendering increases very significantly, as is done in such cases? Thank you......

Olga Belova, hello. Do not put a lot of portals on the number and size of leaves. Put one - size window. 😉

But it will not mean that the geometry intersects the portals? Those. The inner frame is not important .... thanks ... PS take your lessons .... thank you very clear ...

It is necessary to do so, so as not to overlap with the frame portals. That is a little push from the portal frame. About how best to do - many portals or one, the better one. The quality of light is not affected, and the geometry of the beam too. All jumpers are afraid of losing you (the shadow of them) gives the sun and not a portal.

Create a room outside set VRay Sun light source "rays" that falls through the window into the room, but when rendering the room is not filled with light and is not illuminated. On the floor and walls of discarded circuit formed by light window openings, but the light is not scattered inside the room = (how to fix screen:

The first thing that comes to mind - including the Global ovseschenie. One gets the feeling that it does not work. Also check - whether included in a global illumination sky .... the feeling that vyublen GI and GI rendera.A an attempt must be included otherwise it will be dark. 🙄
