VRaySky and ColorCorrect tutorial

ColorCorrect + V-RaySky

While working with V-ray Renderer it's often arises the need of using a specific V-Ray map - VRaySky to illuminate the 3d scene. In most cases the standard settings of the map is quite sufficient. But sometimes the color saturation is too high. It gives a strong yellow or blue light. Unfortunately, a combination of ozone and turbidity parameters only, does not always provide the desired result. But as a way out of this situation is the ColorCorrect using. It's enough to put into a ColorCorrect Source slot the VRaySky map and adjust the Saturation value to get the proper illumination.

ColorCorrect + V-RaySky using

In practice this is the most flexible way to manage VRaySky illumination.

Hello, Lamu. VraySky Parameters - This scroll parametric parameters HDR VRaySky card. To see the parameters of a scroll of the map, like any other in 3ds Max, you must open it in the Material Editor😉

I try, it is impossible! You could not even write again in more detail the sequence? And then the picture is clear all like, but in practice it is impossible.

Anton, a hint advanced level and assumes a basic level of knowledge, in this case about VRaySky. Most likely you have a question not in the ColorCorrect, namely that you are not fully familiar with the scheme of VRaySky. If you have mastered the technique of lighting scenes via VRaySun ligaments and the VRaySky, the trick described in the tutorial, you will immediately understand 🙂

Thank you, I'm still a bit figured out on their own, although it is not sure what is right to the end. In general, it is not enough lesson on proper lighting scenes (for interiors, including a) because under scheme 2: 2, it looks and it turns out quite differently.

This problem, after I reinstalled my system in Max had a problem related to the visualization VraySun + VraySky. When using the sun I automatically accept VraySky it is displayed in Evmirovment tab. And when I visualize or all dark blue, or yellow + texture of the object is not visible. Tell me what could be the problem and how to solve it?

I thought maybe it would help me in the end did not help. You could tell me what's the problem? Watched threads on various forums have not seen similar problems. Some were outraged that they had the shadow of a blue tint, but the sky they were normal, and I have either all yellow or all dark blue + no texture on the object he just black. If you please tell me what the problem is or where to find the answer?

Of Rodion, to make the right decisions as to what you watch on the visualization, you just need to understand the essence of the work VraySun + VraySky. Otherwise, it simply can be no question of using these tools. Unfortunately, at the moment, we do not know any interesting lessons or guidance that could simply and clearly explain the operation of these instruments. For this reason, we will write a detailed, comprehensive and clear coverage of all a lesson on using VraySun and VraySky. In any case, you must understand that to present the whole theory here in the comments just not physically possible. To describe it, you will need a multi-page guide with illustrative images. In short, VraySky - HDR is a parametric map, imitating the scattered light of heaven. More information about its parameters you can read in a help-Ray for the V . The main parameter that you need to understand is pusth slot Sun node, clicking on which you will be asked to select the source of light, the geometrical position in which the stage will depend on the strength and color VraySky glow. VraySun - directional light source designed to simulate the glow of sunlight, similar to the built-in 3ds Max Target Direct. More options c VraySun you can read in a help-Ray for the V . Do it as you do. Then, from the tab Environment Environment and Effects window, using Drag and Drop, drag VraySky and tossed it into the empty balloon material Editore, instensom. So you will be available to its parameters. We click on the node and slot in of Sun viewport choose VraySun. Then Sun node name appears VraySun. This would mean that VraySky now associated with VraySun and on its geometrical position will change color and intensity VraySky glow. Now temporarily disable itself VraySun, removing the check mark from its setting Enabled. So you turn it off completely and on setting the time, get rid of his bright% B St.5cheniya prezhigayuschego scene. After that Sun moves and do test renders, you will see how the Sky glow color. Then, when you will pick up the best light of heaven, back plug Sun and changes its parameter Intensity multiplier. By reducing it, and pick up the desired brightness of the sun. And necessarily involve the GI, or you just do not see the work of Sky, which is the source of the secondary light (GI). What is the GI and read how to use it in a lesson the V-Ray Indirect illumination .

Hello RenderStuff. Just yesterday, I puzzled how to get rid of the excessive blueness! Now everything is clear, thank you. But there was another question: If the Sun in the lower stage is lower, then there is already a yellowish tint, and how to be with him?

ASRockus, if you're talking about the color of the sky is cool "turbidity" in the least. Well, the same adjustments of color can change the HUE value🙂🙂 But the color of the sun more difficult. In fact, for greater flexibility, instead of Wray dignity can juzat any other directional light. and it has to be played with in its temperature (color) and of other settings. Just plug in Vreyshedous settings. ^^

Hi Artem. Less than the value of 2 does not deliver. And about another source, it's like? in conjunction with the Sky? I do not quite understand, if not difficult to verify.

http://renderstuff.com/page-689/#835 All the same only instead of Vray Sun you use well, such as Target Direct, in its turn on the shade and instead of the Shadow map rollout General Parametrs absorbs Vray Shadows. Then do whatever you want, change the color intensity of the size of the light source and so on. For soft shadows rollout VrayShadows Params put a check in front of Area Shadows. Blur shadows depends on the values ​​* size Hope helped)

10 Aug, 2011 # Re: VRaySky and ColorCorrect tutorial
And the intensity of the source (say Target Direct) has to turn in his own parameters Sky.V parameters twisted (Targ. Dir.) Zero effect it. Did I do that? Thank you!


9 Aug, 2011 ASRockus
10 Aug, 2011 # Re: VRaySky and ColorCorrect tutorial
And if you use the Target Dir + Sky., Is missing on the floor or the wall (depending on the direction) of the light area of ​​the opening of the window, as is the case with the use of sun + sky. Or something I do not understand (I'm still just learning) 🙂

Privet.VRaySky - it's just a parametric map. Same as any other parametric map of 3ds Max. Its parameters only its same properties can be changed. It's just that it is one of the parameters of the container is controlled by the vector with the object and purpose. This container can be any object that is the goal. This may be at least a light source, though Target camera. Irrelevant. Importantly, using this vector to define a container space of the scene from which the directions will change color parameters VRaySky, as well as, its brightness and the brightness of the sun at the point it. That look, it looks like VRaySky card: http: //www.spot3d.com/vray/help/150SP1/vraysun_sky_param.htm See right bright spot, clearly mimics the solar disk? that is the location of the disk to the VRaySky, it depends on the direction of the control container only vsego.Nikakogo impact on the parameters of the object that defines the vector, VRaySky not imeet.Sun intensity multiplier - only sets the brightness of this point, and with it the entire map VRaySky.Esli vector for VRaySky you set the direction of the light source, the brightness can be adjusted only by his own settings😉 And light up from Target Direct, you can not see because you have not configured it as needed. First, the spirit its direction so that it shines is in the direction in which you want it illuminates the area on the floor or the second attitude stene.Vo its intensity, to see the spot glare from the rest of the lighting in the third stsene.V , specificity Target Direct is that it illuminates only a fixed area of ​​the stage space and you need to extend this zone to one that completely cover your window aperture😉

Thank you for the clarification ogromennoe (as always clear, and objective) .Vot why I did not see "light in the window" and changes in the scene when the intensity parameter wrap at Target Direct, the whole thing in this scroll Hotspot / Beam, Falloff / Field right? Thank you!

RenderStuff, and you do not plan to write a how to use the Color korektom. And it does not work that it set it up with Vray sky / I can not remove the yellow tint of the light. : |

Here I am tried korektirovat color VraySky dragging it in the Output type of card, and output together with the dragging VraySkay slot Environment Map? Create automatically replacing VraySky. Well of course the editor VraySky materials VraySan assign manually. Then you can adjust an output color directly to the map curves. As for me is much more convenient and clearer work with color channels than ColorCorrect. Well this is my opinion. I advise you to try. 👍

I forgot to say. When you drag the Output card from the slot investments VraySky Environment Map, select the type of instans copy.

Hello!

To be honest, it's completely unclear what exactly caused the difficulty in understanding ColorCorrect.

Nevertheless, the variant suggested by you, theoretically completely analogous to that described in the article, with the only difference being that in the role of the corrective map, Output should be used instead of ColorCorrect.

However, unfortunately, only theoretically ...

The main misconception about VraySky is that you need to adjust its color. But this is stupid. The color of VraySky is excellent. He is exactly what the light of the sky must be - blue. Its correct to absolutely nothing. The main problem of VraySky is that its blue color is saturated with a rhyme, that is, it has too high saturation.

Returning to Output, this card does not control the color saturation. With Output you can only increase or decrease the brightness of the RGB color channels.

Theoretically, in order to reduce the saturation of a certain color, it is necessary to dimmer its channel. For example, in our case, VraySky is saturated with blue and we theoretically need to mute the blue (B-channel). However, in practice, pulling the B-channel schedule, in RGB mode, at the Output card, we do not translate the VraySky color to a more gray one, as Saturation does in ColorCorrect, but only change the color balance by driving the saturated blue into dirty yellow-green: D What will be worse than VraySky without correction. In addition, making one of the channels dimmer, together with it, the overall brightness of VraySky also decreases.

Using ColorCorrect, not Output, the value of Saturation changes with a single numeric field. Everything is extremely simple. In the Environment you put ColorCorrect, in ColorCorrect you put VraySky. Then in ColorCorrect you change the value of HSV Space Saturation. All!

Roma, we are glad that you joined the discussions of our lessons, however, be more careful with advice that could mislead other trideshniki. Do not give unconfirmed advice based only on your own IMHO. Unfortunately, the Output option does not work as it should. To correct VraySky, you should use ColorCorrect.

If you have any difficulties in mastering ColorCorrect, then click on the link that Max gave you and there ask questions about the work of ColorCorrect. We will help you to understand everything😉

And how can VraySky The adjusted by maksovskogo ColorCorrection? and that due ColorCorrecta 3dmax Design 2012 takes off ...


10 Aug, 2011 Anton (Staff Author)
21 Nov, 2011 # Re: VRaySky and ColorCorrect tutorial
That is completely analogous. Doing the same things and that with the ColorCorrect, and then twist the Saturation slider to the left to desaturate VraySky so far as is necessary. To correct VraySky, described in this lesson, ColorCorrection fits no worse ColorCorrect😉

Hello, Render Stuff! The issue of such a plan😁o you need to tie VRay Sky with VRay Sun in the Colour Correct?


10 Aug, 2011 Anton (Staff Author)
3 Jan, 2012 # Re: VRaySky and ColorCorrect tutorial
Hello! Meaning ColorCorrect, in isklyuchitalno color saturation correction of VRaySky. No relation to the most conjunction VRaySun and VRaySky, ColorCorrect not. According to this VRaySun VRaySky and to do all that without ColorCorrect😉

3 Jan, 2012 # Re: VRaySky and ColorCorrect tutorial
Yeah, that is, we connect them, and then just saturation Wray sky twist in minus correctness of color and throw in invayroment pravelno ??? I know? Just lesson you on screen did not show, and I hesitated a little bit =)

This is a lesson PRO level. He initially assumes that you already know well how to use the dignity and Skye😁 In this, he does not explain the basics of working with these tools. I advise you to read this: http://renderstuff.com/vraysky-colorcorrect-tutorial-46/ And also this: http://renderstuff.com/svobodnoe-3d-obsuzhdenie-21-vraylight- v-oknah-pri-osveshhenii- interera-vray-sun-i-sky / # 1383 Then, surely you can better understand what to do with both. In any case, if you are not yet entirely clear idea how to use sky and sun in viriey, their correction, the last thing you should be currently interested in. I advise you to carefully read the disc on the link above - entirely. Do not go into the jungle. Understand the basics. If something is not clear, ask the question right there or create a new topic, if there is no appropriate topic😉
