Good day guys would like to learn how to make the effect of the lamp is not modeled light and do not use fotoshop.to vivo Recording want to do it in max with Vraem.

It is necessary to use a light source VRayIES. It applies Map IES ( http://ru.wikipedia.org/wiki/IES ), which gives such an effect. Such cards do many manufacturers of lighting fixtures. They actually incorporated information about the color of the source, form, and much more.

MOPS, probyval ieski but was never able to find you have a can share ?! or to explain how to work with these ieskami to get exactly the kind of effect.

Cem, hello! To get just such a pattern from the lamp like yours on the screenshot, then there is an option only one - look very IES a file to such a lamp, of course, if you know a company manufacturer and model, it is possible to find, but again, not the fact that you will find ๐Ÿ™„. Alternatively, I know that there is a utility for creating IES files (IES generators) with information about the fixture (the shape of the pattern, brightness, color, etc.), you can try, respectively, in such a generator to re-create something similar to the pattern that you need get. At the expense of the program just can not say, because in dense faced with (usually downloaded ready IES files), I heard about them and superficially interested, but did not work. I only know that there need to plot the graph and close to it immediately drawn glow result, well, in general, something like this ๐Ÿ™‚. Maybe Max and Anton that any specific advise on such generators can then create a new Temko ... I think it will be interesting to all.

A little Googling and found a generator. Still quite a useful thing, besides still small, free ๐Ÿ‘. This is a reference to the generator itself: the IES Generator v.4 - Policy Copyright (the C) 2006, Karbaras at rambler.ru

Good afternoon. Please help me with spotlights. I do not see them on the render. I install, Vray Ies, Card Opt ies. To wind power. Still, when rendering, light or does not appear. There is not patterned drawings, not just flashes on any day. The impression that I did not set any fixture. The stage lighting scheme used Vray Sun + VRay Sky + Skylight portal.

cem, catch

Download little cards IES + viewer (IES viewer) is very convenient.

And now you get the desired effect. In the archive I have not found exactly what you need, so we will do mix. I'll use just such a card: To build a room, the ceiling hung a cylinder, symbolizing the chandelier. Between him and the ceiling set 4 IES istoknika (Instance) Next, the first source of IES IES invest the necessary card. In the other, it will automatically appear as horses Instance render Or To get exactly this, then, as Dennis said - you need just such a card IES. Or look or Draw in the generator (see above Denis gave a link), the way the first time I did it all. Previously we did not have to work with the IES-kami.

Cem, mOPs hello! Of Cem, to the account of the creation of such an effect, MOPS all true you painted ๐Ÿ‘, because as you can see on your screenshot, pattern created by multiple light sources (in your case of 6). Here is my collection of IES fotometrikov, you can look something like:

Download the largest collection of IES files .

Here I am found one IES'ok generator - the more flexible settings and easy to use):

Allegory, try to turn off all fluorescent lighting (Vray Sun + VRay Sky + Skylight portal) and see whether the IES visible light. It seems to me that it is not visible because the light from the Vray Sun + VRay Sky + Skylight portal dominates significantly. (PS one link is enough and not all that piccy.info gives you one picture)

Allegory try IES sources down a little lower, so they were slightly below Possible sources just hid in the shelf or cabinet luminaire.

Yes, the results are out with it ... so graphically, and from where it is visible that it is necessary to correct๐Ÿ˜‰. And interesting to see what happened.

Allegory, the causes can be many.

Firstly, as the mOPs said , your ieski can simply be pushed into the body of luminaire models and their glow just not visible because it is blocked by geometry.

Secondly, different illumination IES files looks differently, including the shape and direction of the emission can be very different. It is everyday situation where CHD illumination directed in the opposite direction. The opposite direction of the normal / target with VRayIES.

In any case, your VRayIES, looks very strange. No target has not seen, on the container Lite, etc .. Theoretically, VRayIES-rendered faster than maksovsky Photometric Light, but the second is much more convenient. That there is only one Distribution Zone, with built-in viewer IES. So what if you're more render time not confused, it is better to use maksovskim fotometrikom. It is more technologically practical and easy to use.

Third, depending on the exposure of your 3d scenes , require different brightness (moshnost) light sources so that they became visible glow. Therefore, alternatively, try to increase the brightness of your source, two, three, ten to twenty times. While it will not be visible. If it does not, then see the first two points๐Ÿ˜‰

hi all, hello Anton nashet iesok, had the same problem with fotometrikami, they are not visible, it is necessary to wind it very much, I just picked up and put in the unit setup instead meters centimeters, they are the same physical korektno like may chasm if rabotaesh in meters ๐Ÿ™‚
