Searching advise for interior lighting

[NOPE]

Usualy I follwow this method when I deal with daylight interiors ..

 

1.Use direct or sunlight+vray lights placed near the windows..

 

But now I have to do interior with many windows almost no walls...and I don`t want to use vray lights ..it will take rendertime.Some tips ?

If you have a lot of windows then you should be able to get away with just using vray sun/sky with no plane lights. It may help your GI calcs if you turn off cast shadows for your glass material too.

Also, in my experience more windows = more light = less render time. It's the darker interiors where Vray has to work harder to bounce the light around that take the longest.

Thanks mate ..So using Vray sun/sky light should be enough.

I always wondering .. is it possible to achieve enough GI in dark interiors with increasing generate GI in object properties ..?

you can try the VrayOverride material with a light color, at least on floor and ceiling to help light propagation and by the way control the color bleeding
