This are the Settings I used at last, as suggested by valerostudio:

() Set the "Max. subdivs" to 100 (one hundred). Leave the "Min. subdivs" to 1. (Done)
() Set the primary GI engine to Brute force GI. Do not change the subdivs. (I left the Irradiance Map option, there was no "brute force" in the version of vray i'm using)
() Set the light cache interpolation samples to 5. (I assumed this is called "Filter Samples in the version i'm using, if so, done)
[] Noise threshold 0.001
The rest of the sugestions were already set by default.

I think the render improved a lot, feel a lot better with the result, i'm posting the image for your critics if possible. Thank you!

Part of the issue I see is that you are using an emitter material in 1.49.01. The emit material is not like the VRay light material in Max and creates a lot of splotches and noise. I have found the emitter material in 2.0 to be better but it is still not the VRay Light Material unfortunately. 2 Suggestions I have

Try using "The Universal Method" for your render settings. This can be found on the Chaos Forums under Max Tutorials.

Read through this article and approach your light setups the same what a photog would.

Valero thank you very much. I'm over the thread you sent from chaosgrouo forums, I had to dig a bit but i found the "universal settings" which i'm applying to my render at this moment. Also the article was very interesting, doesn't seem as easy to me to transfer that information to a render but i will try it and hopefully dominate it.
Again thank you

I think the final render looks good, the added "touch" I think you're looking for is probably done through post-processing, like adding a soft glow to the light fixtures so they don't look like white sharp lines. I believe the noise you are getting is due to the fact that you are lighting mostly with emmisive materials, am I correct? One thing you could try would be to put an invisible rectangular light just below your ceiling to act as a ambient light and reduce your emmisive lights to something closer to what you had in your first final render. Then in post just add a diffused glow to the light areas and I think you will see a dramatic change.

Just my 2cents

Thank you Rob. Yes i know the importance of post-processing and that's also why I was looking for a sharper original render because i feel any editting I do in photoshop just enhances all the grains.
The last render I posted had a rectangular light, wich I just now realized that it was over the same plane as the ceiling and that's why it looks smudgy, i'm also using IES wich is where comes most of the lighting (i think), initially it did come from emmissive material but I had reduced the intensity once I put the rest of the lights.
My post processing skills are as intuitive as rendering (still lots of trial and error) reading from yoy that a soft glow for lighting is probably what it needs did help a lot, I also placed correctly the rectangular light and aumented its intensity, that improved a lot as well, so i guess i'm getting where i want step by step, render time is taking 2.5 hours so i'm guessing i also need lots of patience. I had the rectangular light reflected on the glasses but i just read how to fix that.
Again thank you very much for your coment i will be posting the "real" final render for critics (if you may)

Greetings. I was wondering if any of you could recomend a series of tutorials to actually dominate interior scenes with artificial lighting.
I've been on it for a while, i will post these last renders that i'm doing for practice.
I get so frustrated that the test always seems to look better than the final renders. For this particular test i have no idea of the recomended settings to avoid geting such a noisy result, the image feels sloppy, dirty, like there's a lack of detail.
I'm posting a test, a final, and a final v 2.0 where i tried to correct some things that didn't feel right to me but turned out worse that the image rendered before.
I'm posting those so you can see where my frustration comes from, i've followed some tutorials but i don't know if theese scene is quite particular (i have a big window on the back). I'm using SketchUp Pro 8, Vray 1.49 Any coments apreciated. As usual i'm truly grateful just for your reads.
Jose.

PS. I could upload the skp file, wich host would you recomend?

[Edit] Forgot to say the lighting comes from IES and emmisive material, the sun settings are on

Greetings, i'm doing this "simple" interior scene, there is a blue glass division that showed somewhat fine in my tests, except for the part when some glasses rendered in a different blue. I figured it was because of the side of the plane where i added the material, so i decided to convert those planes into volume, push/pull and group and i created solid glasses, then the matterial would be apllied to all the faces (i thought). Now those windows render completelly transparent (no color blue) and no reflection, and i think no refraction, I foun that strange and actually i have no idea of how to solve that. i'll apreciate the feed back, and as always very grateful.

Thank you, i tryed that (change the IES file) and I manage to get more or less what I was looking for, I still need lots of practice for that kind of render (Night Scene, or interior). At this moment (same model) i'm having issues with a glass material, i'll upload some pictures to see if i can get some help, again thank you very much

i'm having the opposite issue, if i apply the material to a plane it renders fine, if i do it to a component or a group then it doesn't shows up in my render...

Greetings. I've been using vray for a while still have lots to learn, at this point i'm having an issue that's already been discussed, i'm using IES lights and they don't render.

Now the thing is i've got a different IES in the model (is not in the same scene) the one i put first renders fine i even change the IES file and did some modifications on the settings (this means lots of trial renders) and i got the effect i was looking for, then for a different lamp, a different room (same model) added a new IES light did all my settings, and they don't show up at all, i really don't know what to do at this poit.

i'm working with GI and BG Color Off (Enviroment) i cheked that lights are on in the Global Switches, the intensity of the light (tried a few already) is set to 9e+07 (wich i think is the maximun).

I would love to get some help, please

So this is the final model, i'm attaching some raw render (no postprocessing)tho i actually like them like this . Well actually it's not final because the client asked me to make some changes that i'm still figuring out, anyways Brookefox asked me to share more, and i wanted to ask exactly what should i share that could be helpful to you guys (masters)?, modelling tips? the model? well let me know, and also let me know any suggestions about the renders

oh and @valerostudio thanx! yes it is now a routine for me, and good to know becouse my coworkers work with 3Dmax, we usually share models.

wow! thank you BrookeFox, sure i'll post more...

Hey i just realize i've had doubts about that for a long time (not about this model in particular), and not vray concerning, but modeling in sketchup, i always wondered why some faces had a different color, still having the default material, sometimes white sometimes a kind of "purpleish grey", now i understand it was because the faces were inverted.Thanks once more!

YES!! That was exactly it, i just changed the face orientation of the water plane and it was fixed! Thanks a lot Mr. eidam655

Greetings Masters

So i'm trying to render this scene, it's a pool, a slide, and a wet-bar (don't know the real name in english) i'm having two issues, one is that the water dessapeared and the other one is that beautiful grey patch that i don't understand where it's comming from! i'm new at vray, for the water material i followed one of Mr. Nomeradona (please forgive if i misspelled your name) tutorials (this one ---> http://sketchupvrayresources.blogspot.com/2011/08/tutorial-water-ripples-in-vray-sketchup.html ) and actually it worked fine untill i started aplying all the rest of materials (the mosaics) ...the scene is not finished but i wanted to do a render test and i freaked out when the grey patched appeared! My first thought was that maybe there were two faces colliding at the curved wall, but what about the stools? anyway i checked, i also read some post here, and i'm sure something like this has been posted before so i'll say sorry in advanced for not finding the solution before posting. Anyways i'll apreciate any help, i'm attaching an image of the model and one of the render (with the grey patch).

Thank you kingsi!
Well i've been working on a scene that i think is finally going the right direction, i still need to polish lots of details. What rendering engine do you use?

Hello SketchUcation Users, I just joined this comunity in hope to improve my renders.

I've used SketchUp quite a long time now, loving how easy it is and how friendly and great looking the presentations can be.
But i'm new to photorealistic rendering, testing some rendering engines had made me stay with Vray, but learning it has been a bit difficult for me, i've been researching reading blogs watching tutorials, but I seem to get doubts all the time that it could be most helpful if i could just directly ask someone with experience. Sadly this softwares are not very common in my country (or in my city) here people uses 3d Max, also Vray as render engine, I've tried asking my coworkers about some of my doubts in vray, but sometimes i get even more confused!

based on all this "kind-of-frustrating" experience is why i come to you, a bit ashamed to ask for help, but then i read "friendly place, and that there were no stupid questions"...

at this moment (wich was the ultimate motivation for me to join the forum) i've been having SU bug splat just before vray ends rendering, (i was trying to render a scene wich lasted about 30 minutes, and SU crashed jus before the last sqare was fully rendered).

If any of you is available throug any instant messaging aplication (like skype) i would really apreciate it.
Thank you in advanced!

ps: english is not my main lenguage, so please forgive any misspelling or grammar errors or just mistakes in general
