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 Â 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?Â
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 ?
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??
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.
Hi ciro,
please learn me exteriore render with hdri .
HI,
I think this is a good/easy starting point: https://www.cg-blog.com/index.php/2011/01/12/vray-light-hdri.htm 😉
Love this tutorials. Just got my subscription today.
“DON´T TOUCH THE SUN.”
it make sense.
thanks ciro
DO NOT MODIFY THE SUN! Is definitely the clue!. Thanks Ciro.
I love you Ciro… I shall never ever again touch the sun!!
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.
Hi Alejandra, probably your V-Ray Physical Camera has WHITE BALANCE on D65 (default value). Put it on NEUTRAL.
