Duplex- Interior

This one gave me hard time. It's my first render with Vray (10.5 or 11).

...With a lot of light leakage along the windows frame and a huge calculation time: 14Hr on AMD 64x2... definitely too long!

Original size is 2000x1500.

Comments are welcome
Cheers,
Marc

Looks nice.

A little color variation of the light could be nice. Maybe you let your arealights work in portal mode and use a HDRI environment.

Rendertime and artefacts: I would try to use Vlados universal method. Than you could test to render the scene without arealights, only a HDRI environment. Portal light or area lights are good for GI per IM, but I suppose so, in QMC+LC mode you can save time if you dosn't use arealights.

Thanks for the comments.

Right, the light is crude... But i'm not quite familiar with HDRI.

The few HDRI testing i did for interior scene brought a lot of rather saturated colors on the white walls, the color depending on the HDR file. I probably miss something...
Do you know any good hdri tutorial i could dig in?

I'll give a try to Vlados method this WE and post the result.

You could use the environment from here:

It's not a HDRI, but it could give you an universal background with some color.

A warm colored spherical HDRI I have posted some weeks befor. Here the file link:

Seems to me that light portals do not work. Whatever HDRI pictures i use in the evironment slots, it makes no differences to my rectangular light... or am i missing something?

In another hand, i found very difficult to control the color balance with HDR lighting (i probably do not have the good HDR files).
I tried to correct the color bringing colors with a rectangular light.
But i found that the environment light cannot go throught a rectangular light. So that i can not mix the rectangular light with the HDR environment light in my scene.
The rectangular light in my scene is just behind the windows and stops the environment light...

Is that normal? or am i missing something again?

i think you have to check on the "light portal" buton in your lights properties

Hi,
I did tried this, but did not get any result.

Is the "light portal" working in your side?

After i installed the RC1, the light portals worked fine.

I did not use them for this test render. Only directional light + hdr environment lighting (IM+LC gi) under RC1
Render time 4Hr in 2000x1500, but the wall are splotchy and the color out of control. (still i like the render time )
BTW, i encountered problem in the texture editor when i tryied to rotate a bitmap by 90deg with the "Tile" option unchecked.

The good thing is that the output file format i choose -by accident- is HDR. I did not know there was such an option. This give good control over the picture in post...
