โ™ฅ Zdravtvuyte, RenderStuff, โ™ฅ please tell me how to get rid of noise in Passo Lighting, setting your standard use. And still on the settings of their observations he noted that for the two nuclear Computers better disable tick Multirass, or render goes on ... The Light cache did not know what to do with the Reconstruction parametrs generally supplied Pre-filter 50, Filter nearest 10, rendering turned lingering ... I had not ever used Filter, so I assume that it slows down the process. In this perspective, there are 7 ies vireevskih, very noisy sphere kot.sozdaet shade (30 sabdivs worth) .Well and 3 VRayLight Plane that light up dark places, two of them only as a vase on the table it had to be excluded from ies, it illuminates her ... all I was trying to make here is that the region render noisy shadows under the table, and the first added 120 sabdivs field that creates such noisy shadows, not shorter pomoglo.Eti experiments I put on a small amount of rendering . Then I put HSph.subdivs raised 120 for some reason, too, all to no avail. And at the very vykl.teni spheres and Plano, left only ies shade, get a clean pass only the shadows of the ies are not dark enough, the feeling that the chairs are hovering over polom.Mozhet is the best option, cat. You need to modify during post-processing? Please help as it is to understand ... ๐Ÿ™‚

Coala, hello!

If you use our configuration, you'd know what to do with Reconstruction parameters in Light Sache . We describe in detail this point in our lessons. As well as responsible for what value Multipass in Irradiance Map and how it really "influences" on rendering speed.

In addition, you use not true Gamma value in your scene, you just have to highlight the dark places light sources. I advise you to read the lesson about using gamma 2.2 . It described in detail the error.

As for the noise in the shadows, then 30 subdivs for spherical lights, - it is very small. A minimum of 60 to a peaceful shade. As for the density (black) shades, it is again a question of scale.

I have no idea exactly how and where you are light sources. They may overlap geometry. This is so the same may be the cause of the noise in the shadows when rendering in-Ray the V .

With regard to the layer-pass Lighting, I can only guess what you mean๐Ÿ˜

It is better to explain everything in your own words, it will be clear what exactly you want skzat๐Ÿ˜‰

Hello Anton, well, I have carefully read your lessons, Reconstruction parameters according to your need to put a filter nastroichkam Nearest c intr.samples 10. But even says this: For the single-core and dual-core systems, is justified by the use of Pre-filter, or a combination thereof in the form of Pre -filter + Filter, where the number of interpolation samples are distributed in half or even a great pass toward prefiltration. I have a dual-core computer I put Reconstruction parametrs Pre-filter 50, Filter nearest 10.When the inclusion Multipass, then render almost at a standstill when it vklyuchena.U course you 6-core computing system, so perhaps you Multipass process does not slow. ..Gammu 2.2 always use just faded badly renders rassmatrivt. Well, the question I had in mind this, the second and the third image is a layer Render Elements is called the VRayLighting, I have it with uneven turns black shadows, kot.smotryatsya a spot ... How to get rid of them? It seems clearly explained ๐Ÿ™„

What's on your render, are not related to GI. Yes, and render settings. Your shadow noise due to incorrect installation and configuration of the light sources.

Disable them all. Leave only the main.
Where did you get it? The lamp?
That disables all but him and see what happens. Will the noise. If so, then the matter in it. Check it at the intersection with the geometry, increases sabdivs etc. If not, then, one by one, the remaining plug. The only way you can find the problem.

As for scale, is not discussed. If it is set up correctly, and the same is true set of color mepping , no vytsyevshih renderings will not. Otherwise, what are you missing something, check out until you find a discrepancy with our recommendations.

With regard to the Render the Elements , the "do not go into the jungle," they do not need .

No laytpassov. Customizable light๐Ÿ˜‰

Anton, I realized, thanks for the reply ... you know the situation was such, I view with rendered vklyuchonnymi render elements, so that later in the process ftoshope using render passes elementov.I found that with such defects, and especially laytpasse seen ... and this I have already my first time, so you should try it razobratsya.Seychas deal with the sources of light, but I have patience zakanchivaetsya.Gammu rechecked with your lesson, do not I have one match was in the field of display gamma of 1.8 was. and when you save the image I show in the override 2,2.Kartinka turns svetlinkaya.Nepravilno yes ??? Do not swear and do not beat๐Ÿ™‚๐Ÿ™‚

Yes, is not correct. Read comet lessons about the scheme. It is mentioned several times๐Ÿ˜

Yesterday I had set up and dismantle, general conclusion taco is always needed in 3d graphics fill light, in addition to the key, otherwise there will be places where light does not fall on the render elements in the layer VRayLighting it will be clearly visible as a black layer mest.Etot helped me to notice it .Svet reconfigure now render in dark areas brighter, just highlight the three sides of the table thanks for pleynami.Anton right direction. The theme is cool then you are discussing, and I missed the last read only "Automatic render of several cameras with preservation" is rendering elements is more for animations prednaznachalis.Nu though stereotypes are crumbling all sorts๐Ÿ™‚๐Ÿ™‚ to make fun of bouncing in anticipation of rendering at night๐Ÿ™‚๐Ÿ™‚ ...

"Is always needed in 3d graphics fill light, in addition to the key" - even I do not agree with this. When you return the setting to V-Ray + the correct location and configuration of the main light source should not be such problems ... He (the main source) and you will have to fill up. But to highlight the individual sources of the object that the dark ...: | In general, it's somehow not very rational to me. It turns you into a stage light "fill" the main, 3 for illumination of the table (the two of them just a bowl on the table: |) + 7 ies My 2 hyaderny computer to jumped out of the window๐Ÿ˜ by pressing F9. By the way a very large contribution to the speed, or rather in the length, rendering it brings the number of light sources. I have the example of a subway car ( http://renderstuff.com/page-723/#discussion) it has experienced. When the scene is like a non-severe and rough render dragged on for 8 hours ๐Ÿ™„ I think the stage lights and vases separately - is superfluous. Again, when the correct setting of the scene, the render engine, mats and surround the picture should get a +/- close to reality, and then store in HDRi + Photoshop fix everything nedosvecheno or overexposed + sharpness and of color, contrast, and everything else.

mOPs I reconfigure and changed all sources ieski quite ubrala.Po illumination table I first turned so that ieski too illuminates the flowers, I respective colors excluded from iesok.I beautifully illuminate them with the Plano Plano excluded from these all colors with vase. And lighting principles nastroiki I looked evermotion stage, but I have never received so adjust stsenu.Prishlos from iesok vireevskih refuse and customize their own way. A fill light is always nuzhen.Kogda doing daily scene is highlighted in Plein okna.A then I could not zakryty.Svet window curtains are arranged at the top in lampy.Nu shorter Do not know any way to get rid of these black shadows in VRayLighting layer, so put around the table of large size Plano and gently illuminate light uniformly raspredililsya ...

coala, see this discussion http://renderstuff.com/page-689/#discussion there kakraz all the nuances of proper lighting interior scenes painted. You write, "... there is room blinds closed," well, then the matter curtain material. If it is to make opaque, then naturally no fill light is not in the room. Well, if it is to do so in reality, then you will have a fill light. After all, in reality, the curtains missing some fraction of the light in the room ๐Ÿ™‚ But what depends on the material of curtains! But if too much dense and rather weak lighting, while supplementing the internal light sources (lamps, sconces, lamps). In general, all as in reality - the closed curtains and dark - on the light - light๐Ÿ˜ Personally, my opinion - to highlight something in the interior scenes - nechesno, because in real life, however there are no hidden extras highlights! But when it comes to the subject of visualization, then yes, there is not only additional illumination and proper environment, and so on ...
