How to dominate "lighting"
-
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

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

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.

RobThank 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) -

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 -
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!
