Lesson 3 | V-Ray Sun and Camera

V-Ray Sun and V-Ray Physical Camera are so simple to use!
Just place them in scene: they work fine since the start with default values :

VIDEO – RESUME :

  • We ALWAYS  will use V-Ray Materials > VRayMtl
  • We ALWAYS assign a generic VRayMtl to the entire scene to test the lighting
  • Place V-Ray Sun   (just click YES to add V-Ray Sky )
  • Load the preset vray-TEST and click render
  • Just move the Sun up and down to see how this affect the scene: it’s like the real sun!
  • If you need more or less ligh don’t modify the SUN! Use Shutter Speed :
    lower values > more light / higher values > less light

EXERCISE :

Download THIS PACK | OBJ Version and play with V-Ray Sun and V-Ray  Camera.

– Test different inclination for the Sun (distance and target are not important, only inclination!)

– Use only Shutter Speed to reduce or increase the light coming in the Camera

– For any doubt check FINAL version

QUESTIONS:

Using a darker gray overexposure is gone. Is it correct to modify Diffuse color to fix overexposures? 
Default V-Ray Gray is the “medium” gray, it’s a kind of  universal reference: Set your lighting using defualt gray as reference and everything will be correctly balanced.

    Hi Ciro,
    when we place camera, light, or sun where should be its position depends on.
    I mean which point we should be consider when we place camera & place light,or place sun
    can you explain all these separately ?

    • Ciro Sannino - Auth says:

      Hi Hina,
      this is just a basic lesson.

      If something I explain in this lesson is not clear feel free to ask!
      Ralated position light/camera is another topic: it’s “exterior light balance”.
      I will talk about in future lessons.

    Hey Ciro!

    I’ve been using for quite some time exponential (color mapping) for my renders, cause linear gives me too bright and dark colors. I see in this particular case that the linear multiply gives a “uniform” color, and when i use exponential it actually is a too bright/dark render. Why this happens??

    • Ciro Sannino - Auth says:

      Hi CAUE,
      getting too bright and dark color usually means you’are not working in “linear workflow”. You can read ton’s of (useless) tutorial around the web: in few words “linear workflow” is the only right setup to work with renders. You have all istructions for this setup in the lesson 2.

    “DON´T TOUCH THE SUN.”

    it make sense.

    thanks ciro

  6. MARTHA MESA says:

    DO NOT MODIFY THE SUN! Is definitely the clue!. Thanks Ciro.

  7. Alejandra Valencia says:

    I love you Ciro… I shall never ever again touch the sun!!

  8. Alejandra Valencia says:

    Hi CIro…

    I don’t know why mi final render has this kind of orange hue to it, the light seems orangish, I rendered the final scene I downloaded and looks exactly the same that the one in te video. I compared all the sun parameters, the material, and everything looks the same, help please.

    • Ciro Sannino - Auth says:

      Hi Alejandra, probably your V-Ray Physical Camera has WHITE BALANCE on D65 (default value). Put it on NEUTRAL.
