Vray rendering question, help with setting up interior + exterior scene

[pwrdesign]

Hi!

 

I'm working with a interior + exterior render atm.

I'm fighting with the Vray settings to get nice overall lightning inside the building and a nice evening view from the outside.

 

The scene is set up with the following:

 

(interior) One Vray Daylight with VraySun and No SkyLight, Juni 1st 14.00

(exterior) One Vray Daylight with VraySun and No SkyLight, Sept 1st 19.00

(interior) Vray Camera

(exterior) Vray Camera

 

Indirect Illumination ON with Irradiance Map and Light Cache

My GI environment is ON and WHITE

 

This is my results atm, in the interior scene the side walls are pure white (A default VrayMtrl with diffuse rgb value of 255,255,255).

 

Is this the correct way to lit a interior scene and exterior scene?

I should mention that I also have some IES lights inside the house.

For a start, dont use values of 255,255,255, nothing is ever perfectly white.

 

Secondly, there is nothing wrong with using vray sun sky for your scenes, but I would use them along side other lights and rigs. if your interior is looking blown out at the windows, adjust your camera to make the scene darker, and then add fill lights, and other lights to brighten and highlight areas. This is the same for your exterior, you would have additional lights in the real world too.

Thanks! Then I'm on the right track!

Hallo again!

 

Been working with these two renders now, and starting to get close! The first deadline was tomorrow morning, but I just got it moved to tuesday morning, so I can do a final render over the weekend if I want to.

 

Do you guys (or/and girls) have any tips for me, what I should look into?

I want this to be sharp and crisp!

The interior looks quite good. Only thing that strikes me there is that the field of view seems pretty wide (ie. the camera lens is too short) which is distorting things a bit much for my taste.

 

The exterior though seems completely different in style and quality. Most noticeably, it's REALLY yellow. An exterior shot should be white balanced such that the color from the sky looks pretty much white on your surfaces (ie. there's no noticeable color cast). A side effect of that will be that the artificial lighting will have an amber or greenish color depending on what type of lights they are (an interior shot will be white balanced to match the lighting so you won't see that amber/green color). Based on that, I think your interior lights are showing up fairly well but the exterior has a pretty extreme color cast. If you're going for a dusk feel, some color cast may be ok but it should be fairly subtle (I check google for reference photos when it comes to that sort of thing).

 

Also your clipped trees have a really strong white halo around them. They may just be poor quality clip maps. One thing you can try is, if you use photoshop go to Layer -> Matting -> Remove White Matte.

Thank you for that comments!

Yes the interior shot is has a pretty crazy FOV, but the architect really wanted to show the stairway and the window in the roof, so I had to go fisheye...

 

I've already removed some of the yellow color at the exterior shot, the reference-image is a summer evening night in sweden, where it can get REALLY yellow/orange. The trees are actually VUE rendered, but I might have been abit too quick when it comes to masking

 

I havnt figured out how to render out Alphas in Vray yet hehe

hey there, i have a problem similar to this,

me too, have a white wall with daylight (vray sun)

but it pinkish(like your first picture) when i render it.

how did you manage to render a white wall?

[pwrdesign]

Take a look at your white balance for your Vray Camera! That helped me alot!

I have a similar problem, I cannot manage to balance the interior-exterior thing in my scenes...Whenever I set up my outdoors to look satisfying, my indoors become to dim, and when I make my interior look good, my outdoors become too blown out...

 

Oh, should I mention the fact that I work with Maya Vray ahhh always some problems with Maya...

Any help would be appreciated!

 

Also whether anyone can help me at this point or not, I would like this thread to live so everyone of us can post all our new achievements and help each other on this painfull interior+exterior case.
