tired of getting the right settings

[chow choppe]

hi all i am attaching a file that i am working on

have read tuorials about vray sun, sky and physical camera everywhere on the net

but once i try to use it in my scene i am not able to understand how to have good settings. either my scene turns yellow, or is it too bright and burning

even my colors of materials get too tinted.

 

i dont know how to keep good settings so that i have a nice day scene with not too yellow light but more of bluish whitish day scene

 

please see the file here. sorry i couldnt upload it to cgarchitect because it was more than allowed limit

easy solution - dont use vray sky and sun. you dont even have to use vray physical camera.

Strat... you should have a vray clinic and cure vray diseases

[chow choppe]

strat i wud like to move ahead with the latest and not just get stuck with conventional methods.

I have seen realistic lighting using vray sun but somehow it doesnt work for me

[STRAT]

lol@jakub

 

what i meant was, dont feel obliged you have to use them or must use them. you dont. you can get, imo, better results and certainly more control without them. i only use the vray sky/sun if i'm in an uber lazy mood. and i rarely use the phys camera.

 

and dont feel using the sky/sun is an advancement on 'conventional' methods either

The thing about VRay PhysicalCamera, sky and Sun is that if you don't know a lot about photography techiniques, then you're in trouble. These are all about getting a good real-life picture, not CG, so you have to learn how to setup a real camera in order to work with them. To be honest, I really enjoy the ease of use the physical system offers, and use it relativelly often. Even for interiors, sometimes using them makes the whole process a lot faster and easier. Of course, you lack a bit of control over things (the sun acts like a sun and so on), but you get used to it.

If you have read all the LWF tutorials, and also tried adjusting the brightnes of the sun/sky (depending on which version of vray, values below 0.1 or 0.07), also make sure your not double gamma adjusting, make sure your rendering unclamped images, and yes it helps to know about ISO & fStops & Shutter Exposures

 

But even with a max camera, if you render floating point images you can still adjust the exposure later.

Rick is right. I am not a photographer myself and I find (for now) the vray camera hard to manage. I personaly use a directiona light and attach it to a vraysky (veru cool feature) because I can have more control over it. If you want to use the vraysun and camera go for it, but don't get the feeling that if you don't you won't get nice results.

How do you attach ur light to vray sky

can u throw more light on the whole process involving directional light and vray sky

 

thanks

[kippu]

well put a vray sky in the environment slot .... give the option of manual node and in that attach your directional light

[BrianKitts]

I have to agree with the things Rick and Strat said, because if you can't get good results without all the physical elements, then you sure are making it even harder on yourself to use the physical elements. I think starting with HDRI's is a better practice to improve your scene lighting, once you've mastered the control of that, then I would make the jump to the physical world.

 

And as also mentioned you should have LWF in your toolbox before you add the physical sky,sun, and cam.

 

But, with all that being said if you still think you "need" to be using them.....check this out, it should help you a bit.

For me, the best setup is VRayPhysCam+VRaySun+VRaySky (applied to the bg and to a VRayDomeLight). In fact, I always set the GI Environment Override to zero, so I can have full control over the amount of light created by the sky and more detailed shadows.

hi rick

 

i will be really grateful to u if u can attach some screenshots of what u r talking about

 

thanks

[Ricardo Eloy]

Screenshots? I don't see why one would need a screenshot for that, Chow. I just said I use a VRay Physical Camera, the VRaySun and the VRaySky applied as a texture to a VRay dome light.

[chow choppe]

hey cool down rick

i didnt know that u can apply vray map as texture to vray dome light

thanks

dunno...I have been using vray for almost 3 years now. it took me sometime to understand how vraysun, vrayligths and vraycam work together indeed and now I use them most of the time for indoors and outdoors too.

 

as Ray & Bkitts pointed, you need to understand how they work before expenting great results.

 

the way I started it was: create the vray sun using and standard cam. the only way to make it fit it was by starting with intensity 0.002/0.005 otherwise it was burning everything around....then you can play with the other sun parameters.

 

find out that vrayphysical cam could get more or less the same ligthing results as the standard cam by setting the shooter speed to 2.0...then you can play with the other vrayphysical cam parameters

 

vrayligth planes...that's the easiest and mainly for indoors.

 

this is very basic and it is a good start to put your vray stuff together, besides getting the rigth settings with your vray setup. as Rick said, I always got the vray envirimental ligth to 0.

 

hope it helps....Eric

 

btw. I do have a full time work designing shops and interior design.
