Best Settings for V-Ray (?!)

Share with your friends!

What are the best-of-the-best settings for V-Ray?

Here the solution:

  1. Set V-Ray as the current rendering engine
  2. Antialiasing: Adaptive DMC / Min=1 , Max=100
  3. Indirect illumination: 1° Brute force + 2° Light cache.
  4. Light cache: 5000 and Interpolation samples to 5.
  5. Color mapping: ‘Clamp output’ and ‘Sub-pixel mapping’ must be off.
  6. DMC sampler: Adaptive amount parameter to 1.0 – Noise threshold 0.005

Are not my words, these setting are on the official V-Ray online guide of Chaosgroup.
They call this configuration “Universal Settings” :

« The ‘universal’ settings comprise a set of settings that we have found to work very well for still images in many situations » – Read more…

We must believe 😀

But look at this. I compared Universal Settings / My Final Settings / My Test Settings / Real Time

Uhmm… I can’t see any miracle in “Universal Settings” ?! Why? O_o

Of course you can see some different reflection, a small difference in brightness, but the truth is that there’s no difference in terms of look and emotional impact.

That’s the point: parameters don’t affect ‘Aesthetic Quality‘.

‘Universal Settings’ represents the best setting about sharpness (6h rendering)…. so remember: In ‘Render Setup’ you have tools to get the same image in less time (36mins), but there’s no way here to affect Aesthetic quality.

Now, the real question is: what affects  Aesthetic Quality‘ ?
This is my list:

  • balance of light
  • the right choice of color
  • dynamic balanced composition
  • photographer’s eye
  • artistic approach
  • detailed 3d models
  • nice shaders
  • nice shot

In fact all these things never change during my 4 tests 🙂
For this reason Aesthetic Quality can’t change, of course.

Usually people make efforts to improve quality, trying and testing all Render parameters: that’s wrong.
« Parameters and Aesthetic Quality are two different things »

Learn parameters to reduce your render time;
Study photograpy/color design/art to improve your Aesthetic Quality.

To your success.


NOTE: The goal of this post is not giving the best settings. This post is an experiment to separate two concepts: sharpness and beauty. Usually we call both “quality”… that’s right but they are two different kind of qualities. I hope to help you understanding where to direct your efforts to improve the results.

    Helpful, tnx :))

    where’s the real time setting? i need for the test, thanks…

    • Ciro Sannino - Auth says:

      hi ginanjar
      “Real Time” has no settings. It’s V-Ray RT.
      just load VRAY RT as active shade in “assign renderer” and run it.

  8. chens says:

    great and helpful tips, thanx sir

  9. amir says:

    i have a question
    do you know a solution to create lights like LED lights by vray? i mean some LED lights that are used in ceiling to clone starry sky…lights like dots

  10. Joe says:

    Very nice! But what settings are you tweaking to reduce the render time so drastically? You showed the universal setting configuration, what is yours?

    • Ciro Sannino - Auth says:

      Hi Joe, “parameters” was not the topic of this post. Anyway if you read the post again I’m sure you can find this link inside: I just remember you that you won’t find any explainations about because this was not the topic of this post.

      • Joe says:

        I realize that. I did find that link, which is to the universal settings chaos group recommends, if you read my comment again however, you will see that is not what I wanted to know. I was wondering about your own settings you say you use, as they are obviously much more efficient than what vray recommends and have an extremely similar aesthetic result.

        • Ciro Sannino - Auth says:

          Sorry for my poor english, what I mean is : this link I suggest you is not only about Chaos settings. There are 3 settings inside: universal, my final and my test settings. I hope to understand your question.

    You rendered the above scene with your final settings at 32 minutes.
    Can you give us an idea about what kind of pc did you use? I tried to use render this scene and the estimated time was about 3 hours! 🙁

    • Ciro Sannino - Auth says:

      Hi Vicktoria, I’m using a NASA pc…. hehe 😉 Did you effectlvely completed the render?

      • VIKTORIA says:

        well… building light cache took about 1:30 hour, the first prepass 2:48 hours and the final render 3:15 hours! That’s my time! 🙂
        If yours, took only half an hour then definately I want a workstasion like yours!
        I know that I do not have the best workstation, but I saw that some parameters of yours, had way to high values than mine, so the render time was much more longer.
        I noticed that the adaptive DMC max subdv (and I compare them with the parameteres of the sofa scene) were 50. Isn’t this a high value??

        Ps.Sorry for my long comment…

        • Ciro Sannino - Auth says:

          Uhm…no, Vicktoria. There’s something wrong at your side.
          Even DMC is 50, light cache is indipendent.

          Try this:
          Go to Render Panel (F10) > Settings (tab) > V-Ray System (rollout) > Default geometry = DYNAMIC

          Render again and let me know.

          • VIKTORIA says:

            Ciro, once again you are right! 🙂
            When I rendered the scene I did not choose YOUR final settings but I left it with the settings it already had. But… after I realised my mistake, and choosing your final settings from vray-final preset, it took me approximately 2 hours. :-(. Better than before, but still longer than you did. I can credit this difference due to the fact that you have a NASA pc!

          • VIKTORIA says:

            I forgot to tell you that I work with an Intel Core2 Quad Q9300@2.50GHz with 4Gb RAM NVIDIA GeForce 9800GT. What’s comments about the above?

    Dear ciro thxs for ur tutorials , but i am not able to download the link….pls hepl me…to download ….txs

    Hello Ciro !

    Thanks a lot for the post. I used your settings they’re fast and great.
    But as you said, we should learn and be familiar with the settings. I don’t want to just keep copying settings without understanding them !
    So could you please list the important settings with brief explanation?

    Would really appreciate it !
