Architectural Renders - Life is Swell

yes, I am aware of the horizon line being too high on this image.
Problem was that the client did not supply a background plate from the right angle or position, so had to use the one that was closest. Unfortunately, it's pretty obvious that the horizon is not right, but what can you do...short of going to the site and taking the shot yourself..

@ adriano.ol: not sure what jamaisVu means?

In French:
Deja vu: Already seen.
Jamais vu: Never seen before.

amazing work!

what was your time frame?

My main question for you is the recessed lights in your scenes. What exactly are you using to create the nice soft lighting coming down from those lights. From the lighting placement shot, it looks like they are off, but in the renders they are on.

Thanx,

horizon line fix...

I have been in this kind of situation several times...
What i have done is to edit the background plate in photoshop and add extra heigh bye extending the sky limit, this is adding an additional sky image to yor current plate (with the correct blending).

thanks

Good suggestion minimum...however I needed to keep the foreground with the road and cars and therefore could not lower the horizon. Only way to get around that would have been to scale down vertically and that would have flattened everything...not good either.

Psy, the render above the settings and the settings posted are from 2 different jobs. Usually the spots are off and only turned on when needed.
The soft shadows are mainly coming from the GI and VRaylights in openings. My spotlights usually do not usually have Area shadows activated.

Your technique of using vraylights in the windows is good, but problematic if you have outdoor elements too. The inside looks bright and well lit, but just outside the windows, the floor is much less bright. I see this in your images too.

I always have problems with lighting indoor scenes with skylight only, even with the help of vray lights it is difficult. It looks to me that the GI doesn't reach far enough, it looks like it's loosing energy too fast. Maybe we need an option for something in between inverse square and the no decay.

flipside,
The VRaylights are one-side so they should not be emiting light to the outside. I am wondering where you can see "problematic" areas where the "floor is much too bright"?
I have attached larger images for you to examine.





I never find using skylight alone is a good option for lighting interiors, even with skylight portals. The skylight drops details like small objects in the room and as you pointed out, does not penetrate deep enough.
That's why I tend to use VRaylights at openings.

Another useful trick is to increase the Generate and Receive GI multipliers to get more illumination into the space. I usually use Generate GI=1.5 and Receive GI = 1.25 for all white walls.

I agree that some more options for light decay would be handy.

In the second pic, the floor is very bright on the inside of the window (and not only because of the reflections imo). Outside the window the floor is much more equally lit, because the vray light points to the inside. The inside is lit by the vray light and the skylight, while the outside is only lit by the skylight, so this is darker.

Another question, do you make your vraylights smaller than your openings, and where do you put them, in the opening, in front of it or behind it?

[flipside]

Ok I forgot you already posted your scene specs...

I see you use store with irradiance map. I noticed that this reduces the detail of the area shadows, it looks like it considers the lights more as portals than as area lights if you check this option.

Hey and I'm not complaining about your work, I think it's great! I'm just trying to understand every detail of the setup and how the portals/area light work.

What's the effect of your skylight in your scenes, imagine if you would turn it off and leave the rest as it is, would it darken very much or is most of your light coming from the vray lights. Is it possible to explain the ratio between skylight/vraylight multiplier? Or maybe how your workflow is in getting the lighting right in such a scene Do you start with skylight only, then add lights, or the other way around?



thanks for your replies!

Hi, I'm from Brazil and some friend tells me to see this post (Life is Swell), I Agree, read all the posts and my question is about the Lights:

1. How many light you use? (I seen 1 direct and 6 photometric vray lights, is this right?)

2. How many tipes u use? (02, I guess...)

Anyway, thanks.

[dejaVu]

flipside & Theobarbosa: So many questions...sorry, but don't have time to answer them at the moment...flat out in production...but will probably write an updated tutorial to outline how I go about setting up lights for most of my interiors.
Hopefully I will address all your questions then.

However, I will wait until VRay 1.1 is released before writting the tutorial as some things may have changed and it would keep the tutorial current for longer.

Will let you know when it's done.

Image Sampler

Dejavu, i´m sorry about the last question, I´m a new user of vray and I didn´t see the lights at the window (I think that be the spots on the roof) I din´t knew the vraylights.

Well, I sow your configuration and a have just one question:

What´s the parameters that you use in Imagesampler (antialiasing) and system?

I´m using fixed rate:1 and I´m asking this because my renderings is taking too slowly...

Anyway, thanks
